Compilers for high level languages generate code that follow certain conventions. These conventions are necessary, in part, for separate compilation to work. One such convention is the @dfn{calling convention}. The calling convention is a set of assumptions made by the compiler about where function arguments will be found on entry to a function. A calling convention also specifies where the return value for a function is found. The calling convention is also sometimes called the @dfn{ABI} or @dfn{Application Binary Interface}. @cindex calling convention @cindex ABI @cindex Application Binary Interface Some programs may not know at the time of compilation what arguments are to be passed to a function. For instance, an interpreter may be told at run-time about the number and types of arguments used to call a given function. @samp{Libffi} can be used in such programs to provide a bridge from the interpreter program to compiled code. The @samp{libffi} library provides a portable, high level programming interface to various calling conventions. This allows a programmer to call any function specified by a call interface description at run time. @acronym{FFI} stands for Foreign Function Interface.

The first thing you must do is create an @code{ffi_cif} object that matches the signature of the function you wish to call. This is a separate step because it is common to make multiple calls using a single @code{ffi_cif}. The @dfn{cif} in @code{ffi_cif} stands for Call InterFace. To prepare a call interface object, use the function @code{ffi_prep_cif}. @cindex cif @findex ffi_prep_cif @defun ffi_status ffi_prep_cif (ffi_cif *@var{cif}, ffi_abi @var{abi}, unsigned int @var{nargs}, ffi_type *@var{rtype}, ffi_type **@var{argtypes}) This initializes @var{cif} according to the given parameters. @var{abi} is the ABI to use; normally @code{FFI_DEFAULT_ABI} is what you want. @ref{Multiple ABIs} for more information. @var{nargs} is the number of arguments that this function accepts. @var{rtype} is a pointer to an @code{ffi_type} structure that describes the return type of the function. @xref{Types}. @var{argtypes} is a vector of @code{ffi_type} pointers. @var{argtypes} must have @var{nargs} elements. If @var{nargs} is 0, this argument is ignored. @code{ffi_prep_cif} returns a @code{libffi} status code, of type @code{ffi_status}. This will be either @code{FFI_OK} if everything worked properly; @code{FFI_BAD_TYPEDEF} if one of the @code{ffi_type} objects is incorrect; or @code{FFI_BAD_ABI} if the @var{abi} parameter is invalid. @end defun If the function being called is variadic (varargs) then @code{ffi_prep_cif_var} must be used instead of @code{ffi_prep_cif}. @findex ffi_prep_cif_var @defun ffi_status ffi_prep_cif_var (ffi_cif *@var{cif}, ffi_abi var{abi}, unsigned int @var{nfixedargs}, unsigned int var{ntotalargs}, ffi_type *@var{rtype}, ffi_type **@var{argtypes}) This initializes @var{cif} according to the given parameters for a call to a variadic function. In general it's operation is the same as for @code{ffi_prep_cif} except that: @var{nfixedargs} is the number of fixed arguments, prior to any variadic arguments. It must be greater than zero. @var{ntotalargs} the total number of arguments, including variadic and fixed arguments. Note that, different cif's must be prepped for calls to the same function when different numbers of arguments are passed. Also note that a call to @code{ffi_prep_cif_var} with @var{nfixedargs}=@var{nototalargs} is NOT equivalent to a call to @code{ffi_prep_cif}. @end defun To call a function using an initialized @code{ffi_cif}, use the @code{ffi_call} function: @findex ffi_call @defun void ffi_call (ffi_cif *@var{cif}, void *@var{fn}, void *@var{rvalue}, void **@var{avalues}) This calls the function @var{fn} according to the description given in @var{cif}. @var{cif} must have already been prepared using @code{ffi_prep_cif}. @var{rvalue} is a pointer to a chunk of memory that will hold the result of the function call. This must be large enough to hold the result, no smaller than the system register size (generally 32 or 64 bits), and must be suitably aligned; it is the caller's responsibility to ensure this. If @var{cif} declares that the function returns @code{void} (using @code{ffi_type_void}), then @var{rvalue} is ignored. @var{avalues} is a vector of @code{void *} pointers that point to the memory locations holding the argument values for a call. If @var{cif} declares that the function has no arguments (i.e., @var{nargs} was 0), then @var{avalues} is ignored. Note that argument values may be modified by the callee (for instance, structs passed by value); the burden of copying pass-by-value arguments is placed on the caller. @end defun @node Simple Example @section Simple Example Here is a trivial example that calls @code{puts} a few times. @example #include #include int main() @{ ffi_cif cif; ffi_type *args[1]; void *values[1]; char *s; ffi_arg rc; /* Initialize the argument info vectors */ args[0] = &ffi_type_pointer; values[0] = &s; /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, &ffi_type_sint, args) == FFI_OK) @{ s = "Hello World!"; ffi_call(&cif, puts, &rc, values); /* rc now holds the result of the call to puts */ /* values holds a pointer to the function's arg, so to call puts() again all we need to do is change the value of s */ s = "This is cool!"; ffi_call(&cif, puts, &rc, values); @} return 0; @} @end example @node Types @section Types @menu * Primitive Types:: Built-in types. * Structures:: Structure types. * Type Example:: Structure type example. * Complex:: Complex types. * Complex Type Example:: Complex type example. @end menu @node Primitive Types @subsection Primitive Types @code{Libffi} provides a number of built-in type descriptors that can be used to describe argument and return types: @table @code @item ffi_type_void @tindex ffi_type_void The type @code{void}. This cannot be used for argument types, only for return values. @item ffi_type_uint8 @tindex ffi_type_uint8 An unsigned, 8-bit integer type. @item ffi_type_sint8 @tindex ffi_type_sint8 A signed, 8-bit integer type. @item ffi_type_uint16 @tindex ffi_type_uint16 An unsigned, 16-bit integer type. @item ffi_type_sint16 @tindex ffi_type_sint16 A signed, 16-bit integer type. @item ffi_type_uint32 @tindex ffi_type_uint32 An unsigned, 32-bit integer type. @item ffi_type_sint32 @tindex ffi_type_sint32 A signed, 32-bit integer type. @item ffi_type_uint64 @tindex ffi_type_uint64 An unsigned, 64-bit integer type. @item ffi_type_sint64 @tindex ffi_type_sint64 A signed, 64-bit integer type. @item ffi_type_float @tindex ffi_type_float The C @code{float} type. @item ffi_type_double @tindex ffi_type_double The C @code{double} type. @item ffi_type_uchar @tindex ffi_type_uchar The C @code{unsigned char} type. @item ffi_type_schar @tindex ffi_type_schar The C @code{signed char} type. (Note that there is not an exact equivalent to the C @code{char} type in @code{libffi}; ordinarily you should either use @code{ffi_type_schar} or @code{ffi_type_uchar} depending on whether @code{char} is signed.) @item ffi_type_ushort @tindex ffi_type_ushort The C @code{unsigned short} type. @item ffi_type_sshort @tindex ffi_type_sshort The C @code{short} type. @item ffi_type_uint @tindex ffi_type_uint The C @code{unsigned int} type. @item ffi_type_sint @tindex ffi_type_sint The C @code{int} type. @item ffi_type_ulong @tindex ffi_type_ulong The C @code{unsigned long} type. @item ffi_type_slong @tindex ffi_type_slong The C @code{long} type. @item ffi_type_longdouble @tindex ffi_type_longdouble On platforms that have a C @code{long double} type, this is defined. On other platforms, it is not. @item ffi_type_pointer @tindex ffi_type_pointer A generic @code{void *} pointer. You should use this for all pointers, regardless of their real type. @item ffi_type_complex_float @tindex ffi_type_complex_float The C @code{_Complex float} type. @item ffi_type_complex_double @tindex ffi_type_complex_double The C @code{_Complex double} type. @item ffi_type_complex_longdouble @tindex ffi_type_complex_longdouble The C @code{_Complex long double} type. On platforms that have a C @code{long double} type, this is defined. On other platforms, it is not. @end table Each of these is of type @code{ffi_type}, so you must take the address when passing to @code{ffi_prep_cif}. @node Structures @subsection Structures Although @samp{libffi} has no special support for unions or bit-fields, it is perfectly happy passing structures back and forth. You must first describe the structure to @samp{libffi} by creating a new @code{ffi_type} object for it. @tindex ffi_type @deftp {Data type} ffi_type The @code{ffi_type} has the following members: @table @code @item size_t size This is set by @code{libffi}; you should initialize it to zero. @item unsigned short alignment This is set by @code{libffi}; you should initialize it to zero. @item unsigned short type For a structure, this should be set to @code{FFI_TYPE_STRUCT}. @item ffi_type **elements This is a @samp{NULL}-terminated array of pointers to @code{ffi_type} objects. There is one element per field of the struct. @end table @end deftp @node Type Example @subsection Type Example The following example initializes a @code{ffi_type} object representing the @code{tm} struct from Linux's @file{time.h}. Here is how the struct is defined: @example struct tm @{ int tm_sec; int tm_min; int tm_hour; int tm_mday; int tm_mon; int tm_year; int tm_wday; int tm_yday; int tm_isdst; /* Those are for future use. */ long int __tm_gmtoff__; __const char *__tm_zone__; @}; @end example Here is the corresponding code to describe this struct to @code{libffi}: @example @{ ffi_type tm_type; ffi_type *tm_type_elements[12]; int i; tm_type.size = tm_type.alignment = 0; tm_type.type = FFI_TYPE_STRUCT; tm_type.elements = &tm_type_elements; for (i = 0; i < 9; i++) tm_type_elements[i] = &ffi_type_sint; tm_type_elements[9] = &ffi_type_slong; tm_type_elements[10] = &ffi_type_pointer; tm_type_elements[11] = NULL; /* tm_type can now be used to represent tm argument types and return types for ffi_prep_cif() */ @} @end example @node Complex @subsection Complex Types @samp{libffi} supports the complex types defined by the C99 standard (@code{_Complex float}, @code{_Complex double} and @code{_Complex long double} with the built-in type descriptors @code{ffi_type_complex_float}, @code{ffi_type_complex_double} and @code{ffi_type_complex_longdouble}. Custom complex types like @code{_Complex int} can also be used. An @code{ffi_type} object has to be defined to describe the complex type to @samp{libffi}. @tindex ffi_type @deftp {Data type} ffi_type @table @code @item size_t size This must be manually set to the size of the complex type. @item unsigned short alignment This must be manually set to the alignment of the complex type. @item unsigned short type For a complex type, this must be set to @code{FFI_TYPE_COMPLEX}. @item ffi_type **elements This is a @samp{NULL}-terminated array of pointers to @code{ffi_type} objects. The first element is set to the @code{ffi_type} of the complex's base type. The second element must be set to @code{NULL}. @end table @end deftp The section @ref{Complex Type Example} shows a way to determine the @code{size} and @code{alignment} members in a platform independent way. For platforms that have no complex support in @code{libffi} yet, the functions @code{ffi_prep_cif} and @code{ffi_prep_args} abort the program if they encounter a complex type. @node Complex Type Example @subsection Complex Type Example This example demonstrates how to use complex types: @example #include #include #include void complex_fn(_Complex float cf, _Complex double cd, _Complex long double cld) @{ printf("cf=%f+%fi\ncd=%f+%fi\ncld=%f+%fi\n", (float)creal (cf), (float)cimag (cf), (float)creal (cd), (float)cimag (cd), (float)creal (cld), (float)cimag (cld)); @} int main() @{ ffi_cif cif; ffi_type *args[3]; void *values[3]; _Complex float cf; _Complex double cd; _Complex long double cld; /* Initialize the argument info vectors */ args[0] = &ffi_type_complex_float; args[1] = &ffi_type_complex_double; args[2] = &ffi_type_complex_longdouble; values[0] = &cf; values[1] = &cd; values[2] = &cld; /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 3, &ffi_type_void, args) == FFI_OK) @{ cf = 1.0 + 20.0 * I; cd = 300.0 + 4000.0 * I; cld = 50000.0 + 600000.0 * I; /* Call the function */ ffi_call(&cif, (void (*)(void))complex_fn, 0, values); @} return 0; @} @end example This is an example for defining a custom complex type descriptor for compilers that support them: @example /* * This macro can be used to define new complex type descriptors * in a platform independent way. * * name: Name of the new descriptor is ffi_type_complex_. * type: The C base type of the complex type. */ #define FFI_COMPLEX_TYPEDEF(name, type, ffitype) \ static ffi_type *ffi_elements_complex_##name [2] = @{ \ (ffi_type *)(&ffitype), NULL \ @}; \ struct struct_align_complex_##name @{ \ char c; \ _Complex type x; \ @}; \ ffi_type ffi_type_complex_##name = @{ \ sizeof(_Complex type), \ offsetof(struct struct_align_complex_##name, x), \ FFI_TYPE_COMPLEX, \ (ffi_type **)ffi_elements_complex_##name \ @} /* Define new complex type descriptors using the macro: */ /* ffi_type_complex_sint */ FFI_COMPLEX_TYPEDEF(sint, int, ffi_type_sint); /* ffi_type_complex_uchar */ FFI_COMPLEX_TYPEDEF(uchar, unsigned char, ffi_type_uint8); @end example The new type descriptors can then be used like one of the built-in type descriptors in the previous example. @node Multiple ABIs @section Multiple ABIs A given platform may provide multiple different ABIs at once. For instance, the x86 platform has both @samp{stdcall} and @samp{fastcall} functions. @code{libffi} provides some support for this. However, this is necessarily platform-specific. @c FIXME: document the platforms @node The Closure API @section The Closure API @code{libffi} also provides a way to write a generic function -- a function that can accept and decode any combination of arguments. This can be useful when writing an interpreter, or to provide wrappers for arbitrary functions. This facility is called the @dfn{closure API}. Closures are not supported on all platforms; you can check the @code{FFI_CLOSURES} define to determine whether they are supported on the current platform. @cindex closures @cindex closure API @findex FFI_CLOSURES Because closures work by assembling a tiny function at runtime, they require special allocation on platforms that have a non-executable heap. Memory management for closures is handled by a pair of functions: @findex ffi_closure_alloc @defun void *ffi_closure_alloc (size_t @var{size}, void **@var{code}) Allocate a chunk of memory holding @var{size} bytes. This returns a pointer to the writable address, and sets *@var{code} to the corresponding executable address. @var{size} should be sufficient to hold a @code{ffi_closure} object. @end defun @findex ffi_closure_free @defun void ffi_closure_free (void *@var{writable}) Free memory allocated using @code{ffi_closure_alloc}. The argument is the writable address that was returned. @end defun Once you have allocated the memory for a closure, you must construct a @code{ffi_cif} describing the function call. Finally you can prepare the closure function: @findex ffi_prep_closure_loc @defun ffi_status ffi_prep_closure_loc (ffi_closure *@var{closure}, ffi_cif *@var{cif}, void (*@var{fun}) (ffi_cif *@var{cif}, void *@var{ret}, void **@var{args}, void *@var{user_data}), void *@var{user_data}, void *@var{codeloc}) Prepare a closure function. @var{closure} is the address of a @code{ffi_closure} object; this is the writable address returned by @code{ffi_closure_alloc}. @var{cif} is the @code{ffi_cif} describing the function parameters. @var{user_data} is an arbitrary datum that is passed, uninterpreted, to your closure function. @var{codeloc} is the executable address returned by @code{ffi_closure_alloc}. @var{fun} is the function which will be called when the closure is invoked. It is called with the arguments: @table @var @item cif The @code{ffi_cif} passed to @code{ffi_prep_closure_loc}. @item ret A pointer to the memory used for the function's return value. @var{fun} must fill this, unless the function is declared as returning @code{void}. @c FIXME: is this NULL for void-returning functions? @item args A vector of pointers to memory holding the arguments to the function. @item user_data The same @var{user_data} that was passed to @code{ffi_prep_closure_loc}. @end table @code{ffi_prep_closure_loc} will return @code{FFI_OK} if everything went ok, and something else on error. @c FIXME: what? After calling @code{ffi_prep_closure_loc}, you can cast @var{codeloc} to the appropriate pointer-to-function type. @end defun You may see old code referring to @code{ffi_prep_closure}. This function is deprecated, as it cannot handle the need for separate writable and executable addresses. @node Closure Example @section Closure Example A trivial example that creates a new @code{puts} by binding @code{fputs} with @code{stdout}. @example #include #include /* Acts like puts with the file given at time of enclosure. */ void puts_binding(ffi_cif *cif, void *ret, void* args[], void *stream) @{ *(ffi_arg *)ret = fputs(*(char **)args[0], (FILE *)stream); @} typedef int (*puts_t)(char *); int main() @{ ffi_cif cif; ffi_type *args[1]; ffi_closure *closure; void *bound_puts; int rc; /* Allocate closure and bound_puts */ closure = ffi_closure_alloc(sizeof(ffi_closure), &bound_puts); if (closure) @{ /* Initialize the argument info vectors */ args[0] = &ffi_type_pointer; /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, &ffi_type_sint, args) == FFI_OK) @{ /* Initialize the closure, setting stream to stdout */ if (ffi_prep_closure_loc(closure, &cif, puts_binding, stdout, bound_puts) == FFI_OK) @{ rc = ((puts_t)bound_puts)("Hello World!"); /* rc now holds the result of the call to fputs */ @} @} @} /* Deallocate both closure, and bound_puts */ ffi_closure_free(closure); return 0; @} @end example @node Missing Features @chapter Missing Features @code{libffi} is missing a few features. We welcome patches to add support for these. @itemize @bullet @item Variadic closures. @item There is no support for bit fields in structures. @item The closure API is @c FIXME: ... @item The ``raw'' API is undocumented. @c argument promotion? @c unions? @c anything else? @end itemize Note that variadic support is very new and tested on a relatively small number of platforms. @node Index @unnumbered Index @printindex cp @bye libffi-3.2.1/doc/libffi.info0000664000175000017500000006432112430645712012562 00000000000000This is libffi.info, produced by makeinfo version 5.1 from libffi.texi.

File: libffi.info, Node: The Basics, Next: Simple Example, Up: Using libffi 2.1 The Basics ============== 'Libffi' assumes that you have a pointer to the function you wish to call and that you know the number and types of arguments to pass it, as well as the return type of the function. The first thing you must do is create an 'ffi_cif' object that matches the signature of the function you wish to call. This is a separate step because it is common to make multiple calls using a single 'ffi_cif'. The "cif" in 'ffi_cif' stands for Call InterFace. To prepare a call interface object, use the function 'ffi_prep_cif'. -- Function: ffi_status ffi_prep_cif (ffi_cif *CIF, ffi_abi ABI, unsigned int NARGS, ffi_type *RTYPE, ffi_type **ARGTYPES) This initializes CIF according to the given parameters. ABI is the ABI to use; normally 'FFI_DEFAULT_ABI' is what you want. *note Multiple ABIs:: for more information. NARGS is the number of arguments that this function accepts. RTYPE is a pointer to an 'ffi_type' structure that describes the return type of the function. *Note Types::. ARGTYPES is a vector of 'ffi_type' pointers. ARGTYPES must have NARGS elements. If NARGS is 0, this argument is ignored. 'ffi_prep_cif' returns a 'libffi' status code, of type 'ffi_status'. This will be either 'FFI_OK' if everything worked properly; 'FFI_BAD_TYPEDEF' if one of the 'ffi_type' objects is incorrect; or 'FFI_BAD_ABI' if the ABI parameter is invalid. If the function being called is variadic (varargs) then 'ffi_prep_cif_var' must be used instead of 'ffi_prep_cif'. -- Function: ffi_status ffi_prep_cif_var (ffi_cif *CIF, ffi_abi varabi, unsigned int NFIXEDARGS, unsigned int varntotalargs, ffi_type *RTYPE, ffi_type **ARGTYPES) This initializes CIF according to the given parameters for a call to a variadic function. In general it's operation is the same as for 'ffi_prep_cif' except that: NFIXEDARGS is the number of fixed arguments, prior to any variadic arguments. It must be greater than zero. NTOTALARGS the total number of arguments, including variadic and fixed arguments. Note that, different cif's must be prepped for calls to the same function when different numbers of arguments are passed. Also note that a call to 'ffi_prep_cif_var' with NFIXEDARGS=NOTOTALARGS is NOT equivalent to a call to 'ffi_prep_cif'. To call a function using an initialized 'ffi_cif', use the 'ffi_call' function: -- Function: void ffi_call (ffi_cif *CIF, void *FN, void *RVALUE, void **AVALUES) This calls the function FN according to the description given in CIF. CIF must have already been prepared using 'ffi_prep_cif'. RVALUE is a pointer to a chunk of memory that will hold the result of the function call. This must be large enough to hold the result, no smaller than the system register size (generally 32 or 64 bits), and must be suitably aligned; it is the caller's responsibility to ensure this. If CIF declares that the function returns 'void' (using 'ffi_type_void'), then RVALUE is ignored. AVALUES is a vector of 'void *' pointers that point to the memory locations holding the argument values for a call. If CIF declares that the function has no arguments (i.e., NARGS was 0), then AVALUES is ignored. Note that argument values may be modified by the callee (for instance, structs passed by value); the burden of copying pass-by-value arguments is placed on the caller.  File: libffi.info, Node: Simple Example, Next: Types, Prev: The Basics, Up: Using libffi 2.2 Simple Example ================== Here is a trivial example that calls 'puts' a few times. #include #include int main() { ffi_cif cif; ffi_type *args[1]; void *values[1]; char *s; ffi_arg rc; /* Initialize the argument info vectors */ args[0] = &ffi_type_pointer; values[0] = &s; /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, &ffi_type_sint, args) == FFI_OK) { s = "Hello World!"; ffi_call(&cif, puts, &rc, values); /* rc now holds the result of the call to puts */ /* values holds a pointer to the function's arg, so to call puts() again all we need to do is change the value of s */ s = "This is cool!"; ffi_call(&cif, puts, &rc, values); } return 0; }  File: libffi.info, Node: Types, Next: Multiple ABIs, Prev: Simple Example, Up: Using libffi 2.3 Types ========= * Menu: * Primitive Types:: Built-in types. * Structures:: Structure types. * Type Example:: Structure type example. * Complex:: Complex types. * Complex Type Example:: Complex type example.  File: libffi.info, Node: Primitive Types, Next: Structures, Up: Types 2.3.1 Primitive Types --------------------- 'Libffi' provides a number of built-in type descriptors that can be used to describe argument and return types: 'ffi_type_void' The type 'void'. This cannot be used for argument types, only for return values. 'ffi_type_uint8' An unsigned, 8-bit integer type. 'ffi_type_sint8' A signed, 8-bit integer type. 'ffi_type_uint16' An unsigned, 16-bit integer type. 'ffi_type_sint16' A signed, 16-bit integer type. 'ffi_type_uint32' An unsigned, 32-bit integer type. 'ffi_type_sint32' A signed, 32-bit integer type. 'ffi_type_uint64' An unsigned, 64-bit integer type. 'ffi_type_sint64' A signed, 64-bit integer type. 'ffi_type_float' The C 'float' type. 'ffi_type_double' The C 'double' type. 'ffi_type_uchar' The C 'unsigned char' type. 'ffi_type_schar' The C 'signed char' type. (Note that there is not an exact equivalent to the C 'char' type in 'libffi'; ordinarily you should either use 'ffi_type_schar' or 'ffi_type_uchar' depending on whether 'char' is signed.) 'ffi_type_ushort' The C 'unsigned short' type. 'ffi_type_sshort' The C 'short' type. 'ffi_type_uint' The C 'unsigned int' type. 'ffi_type_sint' The C 'int' type. 'ffi_type_ulong' The C 'unsigned long' type. 'ffi_type_slong' The C 'long' type. 'ffi_type_longdouble' On platforms that have a C 'long double' type, this is defined. On other platforms, it is not. 'ffi_type_pointer' A generic 'void *' pointer. You should use this for all pointers, regardless of their real type. 'ffi_type_complex_float' The C '_Complex float' type. 'ffi_type_complex_double' The C '_Complex double' type. 'ffi_type_complex_longdouble' The C '_Complex long double' type. On platforms that have a C 'long double' type, this is defined. On other platforms, it is not. Each of these is of type 'ffi_type', so you must take the address when passing to 'ffi_prep_cif'.  File: libffi.info, Node: Structures, Next: Type Example, Prev: Primitive Types, Up: Types 2.3.2 Structures ---------------- Although 'libffi' has no special support for unions or bit-fields, it is perfectly happy passing structures back and forth. You must first describe the structure to 'libffi' by creating a new 'ffi_type' object for it. -- Data type: ffi_type The 'ffi_type' has the following members: 'size_t size' This is set by 'libffi'; you should initialize it to zero. 'unsigned short alignment' This is set by 'libffi'; you should initialize it to zero. 'unsigned short type' For a structure, this should be set to 'FFI_TYPE_STRUCT'. 'ffi_type **elements' This is a 'NULL'-terminated array of pointers to 'ffi_type' objects. There is one element per field of the struct.  File: libffi.info, Node: Type Example, Next: Complex, Prev: Structures, Up: Types 2.3.3 Type Example ------------------ The following example initializes a 'ffi_type' object representing the 'tm' struct from Linux's 'time.h'. Here is how the struct is defined: struct tm { int tm_sec; int tm_min; int tm_hour; int tm_mday; int tm_mon; int tm_year; int tm_wday; int tm_yday; int tm_isdst; /* Those are for future use. */ long int __tm_gmtoff__; __const char *__tm_zone__; }; Here is the corresponding code to describe this struct to 'libffi': { ffi_type tm_type; ffi_type *tm_type_elements[12]; int i; tm_type.size = tm_type.alignment = 0; tm_type.type = FFI_TYPE_STRUCT; tm_type.elements = &tm_type_elements; for (i = 0; i < 9; i++) tm_type_elements[i] = &ffi_type_sint; tm_type_elements[9] = &ffi_type_slong; tm_type_elements[10] = &ffi_type_pointer; tm_type_elements[11] = NULL; /* tm_type can now be used to represent tm argument types and return types for ffi_prep_cif() */ }  File: libffi.info, Node: Complex, Next: Complex Type Example, Prev: Type Example, Up: Types 2.3.4 Complex Types ------------------- 'libffi' supports the complex types defined by the C99 standard ('_Complex float', '_Complex double' and '_Complex long double' with the built-in type descriptors 'ffi_type_complex_float', 'ffi_type_complex_double' and 'ffi_type_complex_longdouble'. Custom complex types like '_Complex int' can also be used. An 'ffi_type' object has to be defined to describe the complex type to 'libffi'. -- Data type: ffi_type 'size_t size' This must be manually set to the size of the complex type. 'unsigned short alignment' This must be manually set to the alignment of the complex type. 'unsigned short type' For a complex type, this must be set to 'FFI_TYPE_COMPLEX'. 'ffi_type **elements' This is a 'NULL'-terminated array of pointers to 'ffi_type' objects. The first element is set to the 'ffi_type' of the complex's base type. The second element must be set to 'NULL'. The section *note Complex Type Example:: shows a way to determine the 'size' and 'alignment' members in a platform independent way. For platforms that have no complex support in 'libffi' yet, the functions 'ffi_prep_cif' and 'ffi_prep_args' abort the program if they encounter a complex type.  File: libffi.info, Node: Complex Type Example, Prev: Complex, Up: Types 2.3.5 Complex Type Example -------------------------- This example demonstrates how to use complex types: #include #include #include void complex_fn(_Complex float cf, _Complex double cd, _Complex long double cld) { printf("cf=%f+%fi\ncd=%f+%fi\ncld=%f+%fi\n", (float)creal (cf), (float)cimag (cf), (float)creal (cd), (float)cimag (cd), (float)creal (cld), (float)cimag (cld)); } int main() { ffi_cif cif; ffi_type *args[3]; void *values[3]; _Complex float cf; _Complex double cd; _Complex long double cld; /* Initialize the argument info vectors */ args[0] = &ffi_type_complex_float; args[1] = &ffi_type_complex_double; args[2] = &ffi_type_complex_longdouble; values[0] = &cf; values[1] = &cd; values[2] = &cld; /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 3, &ffi_type_void, args) == FFI_OK) { cf = 1.0 + 20.0 * I; cd = 300.0 + 4000.0 * I; cld = 50000.0 + 600000.0 * I; /* Call the function */ ffi_call(&cif, (void (*)(void))complex_fn, 0, values); } return 0; } This is an example for defining a custom complex type descriptor for compilers that support them: /* * This macro can be used to define new complex type descriptors * in a platform independent way. * * name: Name of the new descriptor is ffi_type_complex_. * type: The C base type of the complex type. */ #define FFI_COMPLEX_TYPEDEF(name, type, ffitype) \ static ffi_type *ffi_elements_complex_##name [2] = { \ (ffi_type *)(&ffitype), NULL \ }; \ struct struct_align_complex_##name { \ char c; \ _Complex type x; \ }; \ ffi_type ffi_type_complex_##name = { \ sizeof(_Complex type), \ offsetof(struct struct_align_complex_##name, x), \ FFI_TYPE_COMPLEX, \ (ffi_type **)ffi_elements_complex_##name \ } /* Define new complex type descriptors using the macro: */ /* ffi_type_complex_sint */ FFI_COMPLEX_TYPEDEF(sint, int, ffi_type_sint); /* ffi_type_complex_uchar */ FFI_COMPLEX_TYPEDEF(uchar, unsigned char, ffi_type_uint8); The new type descriptors can then be used like one of the built-in type descriptors in the previous example.  File: libffi.info, Node: Multiple ABIs, Next: The Closure API, Prev: Types, Up: Using libffi 2.4 Multiple ABIs ================= A given platform may provide multiple different ABIs at once. For instance, the x86 platform has both 'stdcall' and 'fastcall' functions. 'libffi' provides some support for this. However, this is necessarily platform-specific.  File: libffi.info, Node: The Closure API, Next: Closure Example, Prev: Multiple ABIs, Up: Using libffi 2.5 The Closure API =================== 'libffi' also provides a way to write a generic function - a function that can accept and decode any combination of arguments. This can be useful when writing an interpreter, or to provide wrappers for arbitrary functions. This facility is called the "closure API". Closures are not supported on all platforms; you can check the 'FFI_CLOSURES' define to determine whether they are supported on the current platform. Because closures work by assembling a tiny function at runtime, they require special allocation on platforms that have a non-executable heap. Memory management for closures is handled by a pair of functions: -- Function: void *ffi_closure_alloc (size_t SIZE, void **CODE) Allocate a chunk of memory holding SIZE bytes. This returns a pointer to the writable address, and sets *CODE to the corresponding executable address. SIZE should be sufficient to hold a 'ffi_closure' object. -- Function: void ffi_closure_free (void *WRITABLE) Free memory allocated using 'ffi_closure_alloc'. The argument is the writable address that was returned. Once you have allocated the memory for a closure, you must construct a 'ffi_cif' describing the function call. Finally you can prepare the closure function: -- Function: ffi_status ffi_prep_closure_loc (ffi_closure *CLOSURE, ffi_cif *CIF, void (*FUN) (ffi_cif *CIF, void *RET, void **ARGS, void *USER_DATA), void *USER_DATA, void *CODELOC) Prepare a closure function. CLOSURE is the address of a 'ffi_closure' object; this is the writable address returned by 'ffi_closure_alloc'. CIF is the 'ffi_cif' describing the function parameters. USER_DATA is an arbitrary datum that is passed, uninterpreted, to your closure function. CODELOC is the executable address returned by 'ffi_closure_alloc'. FUN is the function which will be called when the closure is invoked. It is called with the arguments: CIF The 'ffi_cif' passed to 'ffi_prep_closure_loc'. RET A pointer to the memory used for the function's return value. FUN must fill this, unless the function is declared as returning 'void'. ARGS A vector of pointers to memory holding the arguments to the function. USER_DATA The same USER_DATA that was passed to 'ffi_prep_closure_loc'. 'ffi_prep_closure_loc' will return 'FFI_OK' if everything went ok, and something else on error. After calling 'ffi_prep_closure_loc', you can cast CODELOC to the appropriate pointer-to-function type. You may see old code referring to 'ffi_prep_closure'. This function is deprecated, as it cannot handle the need for separate writable and executable addresses.  File: libffi.info, Node: Closure Example, Prev: The Closure API, Up: Using libffi 2.6 Closure Example =================== A trivial example that creates a new 'puts' by binding 'fputs' with 'stdout'. #include #include /* Acts like puts with the file given at time of enclosure. */ void puts_binding(ffi_cif *cif, void *ret, void* args[], void *stream) { *(ffi_arg *)ret = fputs(*(char **)args[0], (FILE *)stream); } typedef int (*puts_t)(char *); int main() { ffi_cif cif; ffi_type *args[1]; ffi_closure *closure; void *bound_puts; int rc; /* Allocate closure and bound_puts */ closure = ffi_closure_alloc(sizeof(ffi_closure), &bound_puts); if (closure) { /* Initialize the argument info vectors */ args[0] = &ffi_type_pointer; /* Initialize the cif */ if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, &ffi_type_sint, args) == FFI_OK) { /* Initialize the closure, setting stream to stdout */ if (ffi_prep_closure_loc(closure, &cif, puts_binding, stdout, bound_puts) == FFI_OK) { rc = ((puts_t)bound_puts)("Hello World!"); /* rc now holds the result of the call to fputs */ } } } /* Deallocate both closure, and bound_puts */ ffi_closure_free(closure); return 0; }  File: libffi.info, Node: Missing Features, Next: Index, Prev: Using libffi, Up: Top 3 Missing Features ****************** 'libffi' is missing a few features.

We provide an option --disable-builddir to suppress the move into # a separate builddir. # # Defaults: # # $1 = $host (overridden with $HOST) # $2 = Makefile.mk # $3 = -all # # This macro must be called before AM_INIT_AUTOMAKE. It creates a default # toplevel srcdir Makefile from the information found in the created # toplevel builddir Makefile. It just copies the variables and # rule-targets, each extended with a default rule-execution that recurses # into the build directory of the current "HOST". You can override the # auto-dection through `config.guess` and build-time of course, as in # # make HOST=i386-mingw-cross # # which can of course set at configure time as well using # # configure --host=i386-mingw-cross # # After the default has been created, additional rules can be appended # that will not just recurse into the subdirectories and only ever exist # in the srcdir toplevel makefile - these parts are read from the $2 = # Makefile.mk file # # The automatic rules are usually scanning the toplevel Makefile for lines # like '#### $host |$builddir' to recognize the place where to recurse # into. Usually, the last one is the only one used. However, almost all # targets have an additional "*-all" rule which makes the script to # recurse into _all_ variants of the current HOST (!!) setting. The "-all" # suffix can be overriden for the macro as well. # # a special rule is only given for things like "dist" that will copy the # tarball from the builddir to the sourcedir (or $(PUB)) for reason of # convenience. # # LICENSE # # Copyright (c) 2009 Guido U.

If # found, the cache variable $ax_cv_gcc_archflag is set to this flag and # ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is set to # "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is # to add $ax_cv_gcc_archflag to the end of $CFLAGS. # # PORTABLE? should be either [yes] (default) or [no]. In the former case, # the flag is set to -mtune (or equivalent) so that the architecture is # only used for tuning, but the instruction set used is still portable. In # the latter case, the flag is set to -march (or equivalent) so that # architecture-specific instructions are enabled. # # The user can specify --with-gcc-arch= in order to override the # macro's choice of architecture, or --without-gcc-arch to disable this. # # When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is # called unless the user specified --with-gcc-arch manually. # # Requires macros: AX_CHECK_COMPILE_FLAG, AX_GCC_X86_CPUID # # (The main emphasis here is on recent CPUs, on the principle that doing # high-performance computing on old hardware is uncommon.) # # LICENSE # # Copyright (c) 2008 Steven G.

This can be used to # detect the CPU type. # # On output, the values of the eax, ebx, ecx, and edx registers are stored # as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable # ax_cv_gcc_x86_cpuid_OP. # # If the cpuid instruction fails (because you are running a # cross-compiler, or because you are not using gcc, or because you are on # a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP # is set to the string "unknown". # # This macro mainly exists to be used in AX_GCC_ARCHFLAG. # # LICENSE # # Copyright (c) 2008 Steven G.

SP-20 RP SP-4 previous SP The first four argument words on the stack are reserved for use by the callee. Instead, the general and floating registers replace the first four argument slots. Non FP arguments are passed solely in the general registers. FP arguments are passed in both general and floating registers when using libffi. Non-FP 32-bit args are passed in gr26, gr25, gr24 and gr23. Non-FP 64-bit args are passed in register pairs, starting on an odd numbered register (i.e. r25+r26 and r23+r24). FP 32-bit arguments are passed in fr4L, fr5L, fr6L and fr7L. FP 64-bit arguments are passed in fr5 and fr7. The registers are allocated in the same manner as stack slots.

Send questions, comments, complaints, performance data, etc to dl@cs.oswego.edu * Version 2.8.3 Thu Sep 22 11:16:15 2005 Doug Lea (dl at gee) Note: There may be an updated version of this malloc obtainable at ftp://gee.cs.oswego.edu/pub/misc/malloc.c Check before installing! * Quickstart This library is all in one file to simplify the most common usage: ftp it, compile it (-O3), and link it into another program. All of the compile-time options default to reasonable values for use on most platforms. You might later want to step through various compile-time and dynamic tuning options. For convenience, an include file for code using this malloc is at: ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h You don't really need this .h file unless you call functions not defined in your system include files. The .h file contains only the excerpts from this file needed for using this malloc on ANSI C/C++ systems, so long as you haven't changed compile-time options about naming and tuning parameters. If you do, then you can create your own malloc.h that does include all settings by cutting at the point indicated below. Note that you may already by default be using a C library containing a malloc that is based on some version of this malloc (for example in linux). You might still want to use the one in this file to customize settings or to avoid overheads associated with library versions. * Vital statistics: Supported pointer/size_t representation: 4 or 8 bytes size_t MUST be an unsigned type of the same width as pointers. (If you are using an ancient system that declares size_t as a signed type, or need it to be a different width than pointers, you can use a previous release of this malloc (e.g. 2.7.2) supporting these.) Alignment: 8 bytes (default) This suffices for nearly all current machines and C compilers. However, you can define MALLOC_ALIGNMENT to be wider than this if necessary (up to 128bytes), at the expense of using more space. Minimum overhead per allocated chunk: 4 or 8 bytes (if 4byte sizes) 8 or 16 bytes (if 8byte sizes) Each malloced chunk has a hidden word of overhead holding size and status information, and additional cross-check word if FOOTERS is defined. Minimum allocated size: 4-byte ptrs: 16 bytes (including overhead) 8-byte ptrs: 32 bytes (including overhead) Even a request for zero bytes (i.e., malloc(0)) returns a pointer to something of the minimum allocatable size. The maximum overhead wastage (i.e., number of extra bytes allocated than were requested in malloc) is less than or equal to the minimum size, except for requests >= mmap_threshold that are serviced via mmap(), where the worst case wastage is about 32 bytes plus the remainder from a system page (the minimal mmap unit); typically 4096 or 8192 bytes. Security: static-safe; optionally more or less The "security" of malloc refers to the ability of malicious code to accentuate the effects of errors (for example, freeing space that is not currently malloc'ed or overwriting past the ends of chunks) in code that calls malloc. This malloc guarantees not to modify any memory locations below the base of heap, i.e., static variables, even in the presence of usage errors. The routines additionally detect most improper frees and reallocs. All this holds as long as the static bookkeeping for malloc itself is not corrupted by some other means. This is only one aspect of security -- these checks do not, and cannot, detect all possible programming errors. If FOOTERS is defined nonzero, then each allocated chunk carries an additional check word to verify that it was malloced from its space. These check words are the same within each execution of a program using malloc, but differ across executions, so externally crafted fake chunks cannot be freed. This improves security by rejecting frees/reallocs that could corrupt heap memory, in addition to the checks preventing writes to statics that are always on. This may further improve security at the expense of time and space overhead. (Note that FOOTERS may also be worth using with MSPACES.) By default detected errors cause the program to abort (calling "abort()"). You can override this to instead proceed past errors by defining PROCEED_ON_ERROR. In this case, a bad free has no effect, and a malloc that encounters a bad address caused by user overwrites will ignore the bad address by dropping pointers and indices to all known memory. This may be appropriate for programs that should continue if at all possible in the face of programming errors, although they may run out of memory because dropped memory is never reclaimed. If you don't like either of these options, you can define CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything else. And if if you are sure that your program using malloc has no errors or vulnerabilities, you can define INSECURE to 1, which might (or might not) provide a small performance improvement. Thread-safety: NOT thread-safe unless USE_LOCKS defined When USE_LOCKS is defined, each public call to malloc, free, etc is surrounded with either a pthread mutex or a win32 spinlock (depending on WIN32). This is not especially fast, and can be a major bottleneck. It is designed only to provide minimal protection in concurrent environments, and to provide a basis for extensions. If you are using malloc in a concurrent program, consider instead using ptmalloc, which is derived from a version of this malloc. (See http://www.malloc.de). System requirements: Any combination of MORECORE and/or MMAP/MUNMAP This malloc can use unix sbrk or any emulation (invoked using the CALL_MORECORE macro) and/or mmap/munmap or any emulation (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system memory. On most unix systems, it tends to work best if both MORECORE and MMAP are enabled. On Win32, it uses emulations based on VirtualAlloc. It also uses common C library functions like memset. Compliance: I believe it is compliant with the Single Unix Specification (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably others as well. * Overview of algorithms This is not the fastest, most space-conserving, most portable, or most tunable malloc ever written. However it is among the fastest while also being among the most space-conserving, portable and tunable. Consistent balance across these factors results in a good general-purpose allocator for malloc-intensive programs. In most ways, this malloc is a best-fit allocator. Generally, it chooses the best-fitting existing chunk for a request, with ties broken in approximately least-recently-used order. (This strategy normally maintains low fragmentation.) However, for requests less than 256bytes, it deviates from best-fit when there is not an exactly fitting available chunk by preferring to use space adjacent to that used for the previous small request, as well as by breaking ties in approximately most-recently-used order. (These enhance locality of series of small allocations.) And for very large requests (>= 256Kb by default), it relies on system memory mapping facilities, if supported. (This helps avoid carrying around and possibly fragmenting memory used only for large chunks.) All operations (except malloc_stats and mallinfo) have execution times that are bounded by a constant factor of the number of bits in a size_t, not counting any clearing in calloc or copying in realloc, or actions surrounding MORECORE and MMAP that have times proportional to the number of non-contiguous regions returned by system allocation routines, which is often just 1. The implementation is not very modular and seriously overuses macros. Perhaps someday all C compilers will do as good a job inlining modular code as can now be done by brute-force expansion, but now, enough of them seem not to. Some compilers issue a lot of warnings about code that is dead/unreachable only on some platforms, and also about intentional uses of negation on unsigned types. All known cases of each can be ignored. For a longer but out of date high-level description, see http://gee.cs.oswego.edu/dl/html/malloc.html * MSPACES If MSPACES is defined, then in addition to malloc, free, etc., this file also defines mspace_malloc, mspace_free, etc. These are versions of malloc routines that take an "mspace" argument obtained using create_mspace, to control all internal bookkeeping. If ONLY_MSPACES is defined, only these versions are compiled. So if you would like to use this allocator for only some allocations, and your system malloc for others, you can compile with ONLY_MSPACES and then do something like... static mspace mymspace = create_mspace(0,0); // for example #define mymalloc(bytes) mspace_malloc(mymspace, bytes) (Note: If you only need one instance of an mspace, you can instead use "USE_DL_PREFIX" to relabel the global malloc.) You can similarly create thread-local allocators by storing mspaces as thread-locals. For example: static __thread mspace tlms = 0; void* tlmalloc(size_t bytes) { if (tlms == 0) tlms = create_mspace(0, 0); return mspace_malloc(tlms, bytes); } void tlfree(void* mem) { mspace_free(tlms, mem); } Unless FOOTERS is defined, each mspace is completely independent. You cannot allocate from one and free to another (although conformance is only weakly checked, so usage errors are not always caught). If FOOTERS is defined, then each chunk carries around a tag indicating its originating mspace, and frees are directed to their originating spaces. ------------------------- Compile-time options --------------------------- Be careful in setting #define values for numerical constants of type size_t. On some systems, literal values are not automatically extended to size_t precision unless they are explicitly casted. WIN32 default: defined if _WIN32 defined Defining WIN32 sets up defaults for MS environment and compilers. Otherwise defaults are for unix. MALLOC_ALIGNMENT default: (size_t)8 Controls the minimum alignment for malloc'ed chunks. It must be a power of two and at least 8, even on machines for which smaller alignments would suffice. It may be defined as larger than this though. Note however that code and data structures are optimized for the case of 8-byte alignment. MSPACES default: 0 (false) If true, compile in support for independent allocation spaces. This is only supported if HAVE_MMAP is true. ONLY_MSPACES default: 0 (false) If true, only compile in mspace versions, not regular versions. USE_LOCKS default: 0 (false) Causes each call to each public routine to be surrounded with pthread or WIN32 mutex lock/unlock. (If set true, this can be overridden on a per-mspace basis for mspace versions.) FOOTERS default: 0 If true, provide extra checking and dispatching by placing information in the footers of allocated chunks. This adds space and time overhead. INSECURE default: 0 If true, omit checks for usage errors and heap space overwrites. USE_DL_PREFIX default: NOT defined Causes compiler to prefix all public routines with the string 'dl'. This can be useful when you only want to use this malloc in one part of a program, using your regular system malloc elsewhere. ABORT default: defined as abort() Defines how to abort on failed checks. On most systems, a failed check cannot die with an "assert" or even print an informative message, because the underlying print routines in turn call malloc, which will fail again. Generally, the best policy is to simply call abort(). It's not very useful to do more than this because many errors due to overwriting will show up as address faults (null, odd addresses etc) rather than malloc-triggered checks, so will also abort. Also, most compilers know that abort() does not return, so can better optimize code conditionally calling it. PROCEED_ON_ERROR default: defined as 0 (false) Controls whether detected bad addresses cause them to bypassed rather than aborting. If set, detected bad arguments to free and realloc are ignored. And all bookkeeping information is zeroed out upon a detected overwrite of freed heap space, thus losing the ability to ever return it from malloc again, but enabling the application to proceed. If PROCEED_ON_ERROR is defined, the static variable malloc_corruption_error_count is compiled in and can be examined to see if errors have occurred. This option generates slower code than the default abort policy. DEBUG default: NOT defined The DEBUG setting is mainly intended for people trying to modify this code or diagnose problems when porting to new platforms. However, it may also be able to better isolate user errors than just using runtime checks. The assertions in the check routines spell out in more detail the assumptions and invariants underlying the algorithms. The checking is fairly extensive, and will slow down execution noticeably. Calling malloc_stats or mallinfo with DEBUG set will attempt to check every non-mmapped allocated and free chunk in the course of computing the summaries. ABORT_ON_ASSERT_FAILURE default: defined as 1 (true) Debugging assertion failures can be nearly impossible if your version of the assert macro causes malloc to be called, which will lead to a cascade of further failures, blowing the runtime stack. ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(), which will usually make debugging easier. MALLOC_FAILURE_ACTION default: sets errno to ENOMEM, or no-op on win32 The action to take before "return 0" when malloc fails to be able to return memory because there is none available. HAVE_MORECORE default: 1 (true) unless win32 or ONLY_MSPACES True if this system supports sbrk or an emulation of it. MORECORE default: sbrk The name of the sbrk-style system routine to call to obtain more memory. See below for guidance on writing custom MORECORE functions. The type of the argument to sbrk/MORECORE varies across systems. It cannot be size_t, because it supports negative arguments, so it is normally the signed type of the same width as size_t (sometimes declared as "intptr_t"). It doesn't much matter though. Internally, we only call it with arguments less than half the max value of a size_t, which should work across all reasonable possibilities, although sometimes generating compiler warnings. See near the end of this file for guidelines for creating a custom version of MORECORE. MORECORE_CONTIGUOUS default: 1 (true) If true, take advantage of fact that consecutive calls to MORECORE with positive arguments always return contiguous increasing addresses. This is true of unix sbrk. It does not hurt too much to set it true anyway, since malloc copes with non-contiguities. Setting it false when definitely non-contiguous saves time and possibly wasted space it would take to discover this though. MORECORE_CANNOT_TRIM default: NOT defined True if MORECORE cannot release space back to the system when given negative arguments. This is generally necessary only if you are using a hand-crafted MORECORE function that cannot handle negative arguments. HAVE_MMAP default: 1 (true) True if this system supports mmap or an emulation of it. If so, and HAVE_MORECORE is not true, MMAP is used for all system allocation. If set and HAVE_MORECORE is true as well, MMAP is primarily used to directly allocate very large blocks. It is also used as a backup strategy in cases where MORECORE fails to provide space from system. Note: A single call to MUNMAP is assumed to be able to unmap memory that may have be allocated using multiple calls to MMAP, so long as they are adjacent. HAVE_MREMAP default: 1 on linux, else 0 If true realloc() uses mremap() to re-allocate large blocks and extend or shrink allocation spaces. MMAP_CLEARS default: 1 on unix True if mmap clears memory so calloc doesn't need to. This is true for standard unix mmap using /dev/zero. USE_BUILTIN_FFS default: 0 (i.e., not used) Causes malloc to use the builtin ffs() function to compute indices. Some compilers may recognize and intrinsify ffs to be faster than the supplied C version. Also, the case of x86 using gcc is special-cased to an asm instruction, so is already as fast as it can be, and so this setting has no effect. (On most x86s, the asm version is only slightly faster than the C version.) malloc_getpagesize default: derive from system includes, or 4096. The system page size. To the extent possible, this malloc manages memory from the system in page-size units. This may be (and usually is) a function rather than a constant. This is ignored if WIN32, where page size is determined using getSystemInfo during initialization. USE_DEV_RANDOM default: 0 (i.e., not used) Causes malloc to use /dev/random to initialize secure magic seed for stamping footers. Otherwise, the current time is used. NO_MALLINFO default: 0 If defined, don't compile "mallinfo". This can be a simple way of dealing with mismatches between system declarations and those in this file. MALLINFO_FIELD_TYPE default: size_t The type of the fields in the mallinfo struct. This was originally defined as "int" in SVID etc, but is more usefully defined as size_t. The value is used only if HAVE_USR_INCLUDE_MALLOC_H is not set REALLOC_ZERO_BYTES_FREES default: not defined This should be set if a call to realloc with zero bytes should be the same as a call to free. Some people think it should. Otherwise, since this malloc returns a unique pointer for malloc(0), so does realloc(p, 0). LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H, LACKS_ERRNO_H LACKS_STDLIB_H default: NOT defined unless on WIN32 Define these if your system does not have these header files. You might need to manually insert some of the declarations they provide. DEFAULT_GRANULARITY default: page size if MORECORE_CONTIGUOUS, system_info.dwAllocationGranularity in WIN32, otherwise 64K. Also settable using mallopt(M_GRANULARITY, x) The unit for allocating and deallocating memory from the system. On most systems with contiguous MORECORE, there is no reason to make this more than a page. However, systems with MMAP tend to either require or encourage larger granularities. You can increase this value to prevent system allocation functions to be called so often, especially if they are slow. The value must be at least one page and must be a power of two. Setting to 0 causes initialization to either page size or win32 region size. (Note: In previous versions of malloc, the equivalent of this option was called "TOP_PAD") DEFAULT_TRIM_THRESHOLD default: 2MB Also settable using mallopt(M_TRIM_THRESHOLD, x) The maximum amount of unused top-most memory to keep before releasing via malloc_trim in free(). Automatic trimming is mainly useful in long-lived programs using contiguous MORECORE. Because trimming via sbrk can be slow on some systems, and can sometimes be wasteful (in cases where programs immediately afterward allocate more large chunks) the value should be high enough so that your overall system performance would improve by releasing this much memory. As a rough guide, you might set to a value close to the average size of a process (program) running on your system. Releasing this much memory would allow such a process to run in memory. Generally, it is worth tuning trim thresholds when a program undergoes phases where several large chunks are allocated and released in ways that can reuse each other's storage, perhaps mixed with phases where there are no such chunks at all. The trim value must be greater than page size to have any useful effect. To disable trimming completely, you can set to MAX_SIZE_T. Note that the trick some people use of mallocing a huge space and then freeing it at program startup, in an attempt to reserve system memory, doesn't have the intended effect under automatic trimming, since that memory will immediately be returned to the system. DEFAULT_MMAP_THRESHOLD default: 256K Also settable using mallopt(M_MMAP_THRESHOLD, x) The request size threshold for using MMAP to directly service a request. Requests of at least this size that cannot be allocated using already-existing space will be serviced via mmap. (If enough normal freed space already exists it is used instead.) Using mmap segregates relatively large chunks of memory so that they can be individually obtained and released from the host system. A request serviced through mmap is never reused by any other request (at least not directly; the system may just so happen to remap successive requests to the same locations). Segregating space in this way has the benefits that: Mmapped space can always be individually released back to the system, which helps keep the system level memory demands of a long-lived program low. Also, mapped memory doesn't become `locked' between other chunks, as can happen with normally allocated chunks, which means that even trimming via malloc_trim would not release them. However, it has the disadvantage that the space cannot be reclaimed, consolidated, and then used to service later requests, as happens with normal chunks. The advantages of mmap nearly always outweigh disadvantages for "large" chunks, but the value of "large" may vary across systems. The default is an empirically derived value that works well in most systems. You can disable mmap by setting to MAX_SIZE_T. */ #ifndef WIN32 #ifdef _WIN32 #define WIN32 1 #endif /* _WIN32 */ #endif /* WIN32 */ #ifdef WIN32 #define WIN32_LEAN_AND_MEAN #include #define HAVE_MMAP 1 #define HAVE_MORECORE 0 #define LACKS_UNISTD_H #define LACKS_SYS_PARAM_H #define LACKS_SYS_MMAN_H #define LACKS_STRING_H #define LACKS_STRINGS_H #define LACKS_SYS_TYPES_H #define LACKS_ERRNO_H #define MALLOC_FAILURE_ACTION #define MMAP_CLEARS 0 /* WINCE and some others apparently don't clear */ #endif /* WIN32 */ #ifdef __OS2__ #define INCL_DOS #include #define HAVE_MMAP 1 #define HAVE_MORECORE 0 #define LACKS_SYS_MMAN_H #endif /* __OS2__ */ #if defined(DARWIN) || defined(_DARWIN) /* Mac OSX docs advise not to use sbrk; it seems better to use mmap */ #ifndef HAVE_MORECORE #define HAVE_MORECORE 0 #define HAVE_MMAP 1 #endif /* HAVE_MORECORE */ #endif /* DARWIN */ #ifndef LACKS_SYS_TYPES_H #include /* For size_t */ #endif /* LACKS_SYS_TYPES_H */ /* The maximum possible size_t value has all bits set */ #define MAX_SIZE_T (~(size_t)0) #ifndef ONLY_MSPACES #define ONLY_MSPACES 0 #endif /* ONLY_MSPACES */ #ifndef MSPACES #if ONLY_MSPACES #define MSPACES 1 #else /* ONLY_MSPACES */ #define MSPACES 0 #endif /* ONLY_MSPACES */ #endif /* MSPACES */ #ifndef MALLOC_ALIGNMENT #define MALLOC_ALIGNMENT ((size_t)8U) #endif /* MALLOC_ALIGNMENT */ #ifndef FOOTERS #define FOOTERS 0 #endif /* FOOTERS */ #ifndef ABORT #define ABORT abort() #endif /* ABORT */ #ifndef ABORT_ON_ASSERT_FAILURE #define ABORT_ON_ASSERT_FAILURE 1 #endif /* ABORT_ON_ASSERT_FAILURE */ #ifndef PROCEED_ON_ERROR #define PROCEED_ON_ERROR 0 #endif /* PROCEED_ON_ERROR */ #ifndef USE_LOCKS #define USE_LOCKS 0 #endif /* USE_LOCKS */ #ifndef INSECURE #define INSECURE 0 #endif /* INSECURE */ #ifndef HAVE_MMAP #define HAVE_MMAP 1 #endif /* HAVE_MMAP */ #ifndef MMAP_CLEARS #define MMAP_CLEARS 1 #endif /* MMAP_CLEARS */ #ifndef HAVE_MREMAP #ifdef linux #define HAVE_MREMAP 1 #else /* linux */ #define HAVE_MREMAP 0 #endif /* linux */ #endif /* HAVE_MREMAP */ #ifndef MALLOC_FAILURE_ACTION #define MALLOC_FAILURE_ACTION errno = ENOMEM; #endif /* MALLOC_FAILURE_ACTION */ #ifndef HAVE_MORECORE #if ONLY_MSPACES #define HAVE_MORECORE 0 #else /* ONLY_MSPACES */ #define HAVE_MORECORE 1 #endif /* ONLY_MSPACES */ #endif /* HAVE_MORECORE */ #if !HAVE_MORECORE #define MORECORE_CONTIGUOUS 0 #else /* !HAVE_MORECORE */ #ifndef MORECORE #define MORECORE sbrk #endif /* MORECORE */ #ifndef MORECORE_CONTIGUOUS #define MORECORE_CONTIGUOUS 1 #endif /* MORECORE_CONTIGUOUS */ #endif /* HAVE_MORECORE */ #ifndef DEFAULT_GRANULARITY #if MORECORE_CONTIGUOUS #define DEFAULT_GRANULARITY (0) /* 0 means to compute in init_mparams */ #else /* MORECORE_CONTIGUOUS */ #define DEFAULT_GRANULARITY ((size_t)64U * (size_t)1024U) #endif /* MORECORE_CONTIGUOUS */ #endif /* DEFAULT_GRANULARITY */ #ifndef DEFAULT_TRIM_THRESHOLD #ifndef MORECORE_CANNOT_TRIM #define DEFAULT_TRIM_THRESHOLD ((size_t)2U * (size_t)1024U * (size_t)1024U) #else /* MORECORE_CANNOT_TRIM */ #define DEFAULT_TRIM_THRESHOLD MAX_SIZE_T #endif /* MORECORE_CANNOT_TRIM */ #endif /* DEFAULT_TRIM_THRESHOLD */ #ifndef DEFAULT_MMAP_THRESHOLD #if HAVE_MMAP #define DEFAULT_MMAP_THRESHOLD ((size_t)256U * (size_t)1024U) #else /* HAVE_MMAP */ #define DEFAULT_MMAP_THRESHOLD MAX_SIZE_T #endif /* HAVE_MMAP */ #endif /* DEFAULT_MMAP_THRESHOLD */ #ifndef USE_BUILTIN_FFS #define USE_BUILTIN_FFS 0 #endif /* USE_BUILTIN_FFS */ #ifndef USE_DEV_RANDOM #define USE_DEV_RANDOM 0 #endif /* USE_DEV_RANDOM */ #ifndef NO_MALLINFO #define NO_MALLINFO 0 #endif /* NO_MALLINFO */ #ifndef MALLINFO_FIELD_TYPE #define MALLINFO_FIELD_TYPE size_t #endif /* MALLINFO_FIELD_TYPE */ /* mallopt tuning options.

The malloc_chunk declaration below is misleading (but accurate and necessary). It declares a "view" into memory allowing access to necessary fields at known offsets from a given base. Chunks of memory are maintained using a `boundary tag' method as originally described by Knuth. (See the paper by Paul Wilson ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such techniques.) Sizes of free chunks are stored both in the front of each chunk and at the end. This makes consolidating fragmented chunks into bigger chunks fast. The head fields also hold bits representing whether chunks are free or in use. Here are some pictures to make it clearer. They are "exploded" to show that the state of a chunk can be thought of as extending from the high 31 bits of the head field of its header through the prev_foot and PINUSE_BIT bit of the following chunk header. A chunk that's in use looks like: chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Size of previous chunk (if P = 1) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P| | Size of this chunk 1| +-+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | +- -+ | | +- -+ | : +- size - sizeof(size_t) available payload bytes -+ : | chunk-> +- -+ | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1| | Size of next chunk (may or may not be in use) | +-+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ And if it's free, it looks like this: chunk-> +- -+ | User payload (must be in use, or we would have merged!) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P| | Size of this chunk 0| +-+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Next pointer | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Prev pointer | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | : +- size - sizeof(struct chunk) unused bytes -+ : | chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Size of this chunk | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |0| | Size of next chunk (must be in use, or we would have merged)| +-+ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | : +- User payload -+ : | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |0| +-+ Note that since we always merge adjacent free chunks, the chunks adjacent to a free chunk must be in use. Given a pointer to a chunk (which can be derived trivially from the payload pointer) we can, in O(1) time, find out whether the adjacent chunks are free, and if so, unlink them from the lists that they are on and merge them with the current chunk. Chunks always begin on even word boundaries, so the mem portion (which is returned to the user) is also on an even word boundary, and thus at least double-word aligned. The P (PINUSE_BIT) bit, stored in the unused low-order bit of the chunk size (which is always a multiple of two words), is an in-use bit for the *previous* chunk. If that bit is *clear*, then the word before the current chunk size contains the previous chunk size, and can be used to find the front of the previous chunk. The very first chunk allocated always has this bit set, preventing access to non-existent (or non-owned) memory. If pinuse is set for any given chunk, then you CANNOT determine the size of the previous chunk, and might even get a memory addressing fault when trying to do so. The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of the chunk size redundantly records whether the current chunk is inuse. This redundancy enables usage checks within free and realloc, and reduces indirection when freeing and consolidating chunks. Each freshly allocated chunk must have both cinuse and pinuse set. That is, each allocated chunk borders either a previously allocated and still in-use chunk, or the base of its memory arena. This is ensured by making all allocations from the the `lowest' part of any found chunk. Further, no free chunk physically borders another one, so each free chunk is known to be preceded and followed by either inuse chunks or the ends of memory. Note that the `foot' of the current chunk is actually represented as the prev_foot of the NEXT chunk. This makes it easier to deal with alignments etc but can be very confusing when trying to extend or adapt this code. The exceptions to all this are 1. The special chunk `top' is the top-most available chunk (i.e., the one bordering the end of available memory). It is treated specially. Top is never included in any bin, is used only if no other chunk is available, and is released back to the system if it is very large (see M_TRIM_THRESHOLD). In effect, the top chunk is treated as larger (and thus less well fitting) than any other available chunk. The top chunk doesn't update its trailing size field since there is no next contiguous chunk that would have to index off it. However, space is still allocated for it (TOP_FOOT_SIZE) to enable separation or merging when space is extended. 3. Chunks allocated via mmap, which have the lowest-order bit (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set PINUSE_BIT in their head fields. Because they are allocated one-by-one, each must carry its own prev_foot field, which is also used to hold the offset this chunk has within its mmapped region, which is needed to preserve alignment. Each mmapped chunk is trailed by the first two fields of a fake next-chunk for sake of usage checks. */ struct malloc_chunk { size_t prev_foot; /* Size of previous chunk (if free). */ size_t head; /* Size and inuse bits. */ struct malloc_chunk* fd; /* double links -- used only if free. */ struct malloc_chunk* bk; }; typedef struct malloc_chunk mchunk; typedef struct malloc_chunk* mchunkptr; typedef struct malloc_chunk* sbinptr; /* The type of bins of chunks */ typedef size_t bindex_t; /* Described below */ typedef unsigned int binmap_t; /* Described below */ typedef unsigned int flag_t; /* The type of various bit flag sets */ /* ------------------- Chunks sizes and alignments ----------------------- */ #define MCHUNK_SIZE (sizeof(mchunk)) #if FOOTERS #define CHUNK_OVERHEAD (TWO_SIZE_T_SIZES) #else /* FOOTERS */ #define CHUNK_OVERHEAD (SIZE_T_SIZE) #endif /* FOOTERS */ /* MMapped chunks need a second word of overhead ... */ #define MMAP_CHUNK_OVERHEAD (TWO_SIZE_T_SIZES) /* ... and additional padding for fake next-chunk at foot */ #define MMAP_FOOT_PAD (FOUR_SIZE_T_SIZES) /* The smallest size we can malloc is an aligned minimal chunk */ #define MIN_CHUNK_SIZE\ ((MCHUNK_SIZE + CHUNK_ALIGN_MASK) & ~CHUNK_ALIGN_MASK) /* conversion from malloc headers to user pointers, and back */ #define chunk2mem(p) ((void*)((char*)(p) + TWO_SIZE_T_SIZES)) #define mem2chunk(mem) ((mchunkptr)((char*)(mem) - TWO_SIZE_T_SIZES)) /* chunk associated with aligned address A */ #define align_as_chunk(A) (mchunkptr)((A) + align_offset(chunk2mem(A))) /* Bounds on request (not chunk) sizes. */ #define MAX_REQUEST ((-MIN_CHUNK_SIZE) << 2) #define MIN_REQUEST (MIN_CHUNK_SIZE - CHUNK_OVERHEAD - SIZE_T_ONE) /* pad request bytes into a usable size */ #define pad_request(req) \ (((req) + CHUNK_OVERHEAD + CHUNK_ALIGN_MASK) & ~CHUNK_ALIGN_MASK) /* pad request, checking for minimum (but not maximum) */ #define request2size(req) \ (((req) < MIN_REQUEST)?

Chunks of the same size are arranged in a circularly-linked list, with only the oldest chunk (the next to be used, in our FIFO ordering) actually in the tree. (Tree members are distinguished by a non-null parent pointer.) If a chunk with the same size an an existing node is inserted, it is linked off the existing node using pointers that work in the same way as fd/bk pointers of small chunks. Each tree contains a power of 2 sized range of chunk sizes (the smallest is 0x100 <= x < 0x180), which is is divided in half at each tree level, with the chunks in the smaller half of the range (0x100 <= x < 0x140 for the top nose) in the left subtree and the larger half (0x140 <= x < 0x180) in the right subtree. This is, of course, done by inspecting individual bits. Using these rules, each node's left subtree contains all smaller sizes than its right subtree. However, the node at the root of each subtree has no particular ordering relationship to either. (The dividing line between the subtree sizes is based on trie relation.) If we remove the last chunk of a given size from the interior of the tree, we need to replace it with a leaf node. The tree ordering rules permit a node to be replaced by any leaf below it. The smallest chunk in a tree (a common operation in a best-fit allocator) can be found by walking a path to the leftmost leaf in the tree. Unlike a usual binary tree, where we follow left child pointers until we reach a null, here we follow the right child pointer any time the left one is null, until we reach a leaf with both child pointers null. The smallest chunk in the tree will be somewhere along that path. The worst case number of steps to add, find, or remove a node is bounded by the number of bits differentiating chunks within bins. Under current bin calculations, this ranges from 6 up to 21 (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case is of course much better. */ struct malloc_tree_chunk { /* The first four fields must be compatible with malloc_chunk */ size_t prev_foot; size_t head; struct malloc_tree_chunk* fd; struct malloc_tree_chunk* bk; struct malloc_tree_chunk* child[2]; struct malloc_tree_chunk* parent; bindex_t index; }; typedef struct malloc_tree_chunk tchunk; typedef struct malloc_tree_chunk* tchunkptr; typedef struct malloc_tree_chunk* tbinptr; /* The type of bins of trees */ /* A little helper macro for trees */ #define leftmost_child(t) ((t)->child[0] != 0?

Segments also include flags holding properties of the space. Large chunks that are directly allocated by mmap are not included in this list. They are instead independently created and destroyed without otherwise keeping track of them. Segment management mainly comes into play for spaces allocated by MMAP. Any call to MMAP might or might not return memory that is adjacent to an existing segment. MORECORE normally contiguously extends the current space, so this space is almost always adjacent, which is simpler and faster to deal with. (This is why MORECORE is used preferentially to MMAP when both are available -- see sys_alloc.) When allocating using MMAP, we don't use any of the hinting mechanisms (inconsistently) supported in various implementations of unix mmap, or distinguish reserving from committing memory. Instead, we just ask for space, and exploit contiguity when we get it. It is probably possible to do better than this on some systems, but no general scheme seems to be significantly better. Management entails a simpler variant of the consolidation scheme used for chunks to reduce fragmentation -- new adjacent memory is normally prepended or appended to an existing segment. However, there are limitations compared to chunk consolidation that mostly reflect the fact that segment processing is relatively infrequent (occurring only when getting memory from system) and that we don't expect to have huge numbers of segments: * Segments are not indexed, so traversal requires linear scans.

The main fields are: Top The topmost chunk of the currently active segment. Its size is cached in topsize. The actual size of topmost space is topsize+TOP_FOOT_SIZE, which includes space reserved for adding fenceposts and segment records if necessary when getting more space from the system. The size at which to autotrim top is cached from mparams in trim_check, except that it is disabled if an autotrim fails. Designated victim (dv) This is the preferred chunk for servicing small requests that don't have exact fits. It is normally the chunk split off most recently to service another small request. Its size is cached in dvsize. The link fields of this chunk are not maintained since it is not kept in a bin. SmallBins An array of bin headers for free chunks. These bins hold chunks with sizes less than MIN_LARGE_SIZE bytes. Each bin contains chunks of all the same size, spaced 8 bytes apart. To simplify use in double-linked lists, each bin header acts as a malloc_chunk pointing to the real first node, if it exists (else pointing to itself). This avoids special-casing for headers. But to avoid waste, we allocate only the fd/bk pointers of bins, and then use repositioning tricks to treat these as the fields of a chunk. TreeBins Treebins are pointers to the roots of trees holding a range of sizes. There are 2 equally spaced treebins for each power of two from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything larger. Bin maps There is one bit map for small bins ("smallmap") and one for treebins ("treemap). Each bin sets its bit when non-empty, and clears the bit when empty. Bit operations are then used to avoid bin-by-bin searching -- nearly all "search" is done without ever looking at bins that won't be selected. The bit maps conservatively use 32 bits per map word, even if on 64bit system. For a good description of some of the bit-based techniques used here, see Henry S. Warren Jr's book "Hacker's Delight" (and supplement at http://hackersdelight.org/). Many of these are intended to reduce the branchiness of paths through malloc etc, as well as to reduce the number of memory locations read or written. Segments A list of segments headed by an embedded malloc_segment record representing the initial space. Address check support The least_addr field is the least address ever obtained from MORECORE or MMAP. Attempted frees and reallocs of any address less than this are trapped (unless INSECURE is defined). Magic tag A cross-check field that should always hold same value as mparams.magic. Flags Bits recording whether to use MMAP, locks, or contiguous MORECORE Statistics Each space keeps track of current and maximum system memory obtained via MORECORE or MMAP. Locking If USE_LOCKS is defined, the "mutex" lock is acquired and released around every public call using this mspace. */ /* Bin types, widths and sizes */ #define NSMALLBINS (32U) #define NTREEBINS (32U) #define SMALLBIN_SHIFT (3U) #define SMALLBIN_WIDTH (SIZE_T_ONE << SMALLBIN_SHIFT) #define TREEBIN_SHIFT (8U) #define MIN_LARGE_SIZE (SIZE_T_ONE << TREEBIN_SHIFT) #define MAX_SMALL_SIZE (MIN_LARGE_SIZE - SIZE_T_ONE) #define MAX_SMALL_REQUEST (MAX_SMALL_SIZE - CHUNK_ALIGN_MASK - CHUNK_OVERHEAD) struct malloc_state { binmap_t smallmap; binmap_t treemap; size_t dvsize; size_t topsize; char* least_addr; mchunkptr dv; mchunkptr top; size_t trim_check; size_t magic; mchunkptr smallbins[(NSMALLBINS+1)*2]; tbinptr treebins[NTREEBINS]; size_t footprint; size_t max_footprint; flag_t mflags; #if USE_LOCKS MLOCK_T mutex; /* locate lock among fields that rarely change */ #endif /* USE_LOCKS */ msegment seg; }; typedef struct malloc_state* mstate; /* ------------- Global malloc_state and malloc_params ------------------- */ /* malloc_params holds global properties, including those that can be dynamically set using mallopt.

In essence this means that we believe all pointers, sizes, maps etc held in malloc_state, but check all of those linked or offsetted from other embedded data structures. These checks are interspersed with main code in a way that tends to minimize their run-time cost. When FOOTERS is defined, in addition to range checking, we also verify footer fields of inuse chunks, which can be used guarantee that the mstate controlling malloc/free is intact. This is a streamlined version of the approach described by William Robertson et al in "Run-time Detection of Heap-based Overflows" LISA'03 http://www.usenix.org/events/lisa03/tech/robertson.html The footer of an inuse chunk holds the xor of its mstate and a random seed, that is checked upon calls to free() and realloc(). This is (probablistically) unguessable from outside the program, but can be computed by any code successfully malloc'ing any chunk, so does not itself provide protection against code that has already broken security through some other means. Unlike Robertson et al, we always dynamically check addresses of all offset chunks (previous, next, etc).

(Or even less, but this will usually result in a malloc failure.) * MORECORE must not allocate memory when given argument zero, but instead return one past the end address of memory from previous nonzero call. * For best performance, consecutive calls to MORECORE with positive arguments should return increasing addresses, indicating that space has been contiguously extended. * Even though consecutive calls to MORECORE need not return contiguous addresses, it must be OK for malloc'ed chunks to span multiple regions in those cases where they do happen to be contiguous. * MORECORE need not handle negative arguments -- it may instead just return MFAIL when given negative arguments. Negative arguments are always multiples of pagesize. MORECORE must not misinterpret negative args as large positive unsigned args. You can suppress all such calls from even occurring by defining MORECORE_CANNOT_TRIM, As an example alternative MORECORE, here is a custom allocator kindly contributed for pre-OSX macOS. It uses virtually but not necessarily physically contiguous non-paged memory (locked in, present and won't get swapped out). You can use it by uncommenting this section, adding some #includes, and setting up the appropriate defines above: #define MORECORE osMoreCore There is also a shutdown routine that should somehow be called for cleanup upon program exit. #define MAX_POOL_ENTRIES 100 #define MINIMUM_MORECORE_SIZE (64 * 1024U) static int next_os_pool; void *our_os_pools[MAX_POOL_ENTRIES]; void *osMoreCore(int size) { void *ptr = 0; static void *sbrk_top = 0; if (size > 0) { if (size < MINIMUM_MORECORE_SIZE) size = MINIMUM_MORECORE_SIZE; if (CurrentExecutionLevel() == kTaskLevel) ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0); if (ptr == 0) { return (void *) MFAIL; } // save ptrs so they can be freed during cleanup our_os_pools[next_os_pool] = ptr; next_os_pool++; ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK); sbrk_top = (char *) ptr + size; return ptr; } else if (size < 0) { // we don't currently support shrink behavior return (void *) MFAIL; } else { return sbrk_top; } } // cleanup any allocated memory pools // called as last thing before shutting down driver void osCleanupMem(void) { void **ptr; for (ptr = our_os_pools; ptr < &our_os_pools[MAX_POOL_ENTRIES]; ptr++) if (*ptr) { PoolDeallocate(*ptr); *ptr = 0; } } */ /* ----------------------------------------------------------------------- History: V2.8.3 Thu Sep 22 11:16:32 2005 Doug Lea (dl at gee) * Add max_footprint functions * Ensure all appropriate literals are size_t * Fix conditional compilation problem for some #define settings * Avoid concatenating segments with the one provided in create_mspace_with_base * Rename some variables to avoid compiler shadowing warnings * Use explicit lock initialization. * Better handling of sbrk interference. * Simplify and fix segment insertion, trimming and mspace_destroy * Reinstate REALLOC_ZERO_BYTES_FREES option from 2.7.x * Thanks especially to Dennis Flanagan for help on these.

V2.5.3 Tue Apr 26 10:16:01 1994 Doug Lea (dl at g) V2.5.2 Tue Apr 5 16:20:40 1994 Doug Lea (dl at g) * realloc: try to expand in both directions * malloc: swap order of clean-bin strategy; * realloc: only conditionally expand backwards * Try not to scavenge used bins * Use bin counts as a guide to preallocation * Occasionally bin return list chunks in first scan * Add a few optimizations from colin@nyx10.cs.du.edu V2.5.1 Sat Aug 14 15:40:43 1993 Doug Lea (dl at g) * faster bin computation & slightly different binning * merged all consolidations to one part of malloc proper (eliminating old malloc_find_space & malloc_clean_bin) * Scan 2 returns chunks (not just 1) * Propagate failure in realloc if malloc returns 0 * Add stuff to allow compilation on non-ANSI compilers from kpv@research.att.com V2.5 Sat Aug 7 07:41:59 1993 Doug Lea (dl at g.oswego.edu) * removed potential for odd address access in prev_chunk * removed dependency on getpagesize.h * misc cosmetics and a bit more internal documentation * anticosmetics: mangled names in macros to evade debugger strangeness * tested on sparc, hp-700, dec-mips, rs6000 with gcc & native cc (hp, dec only) allowing Detlefs & Zorn comparison study (in SIGPLAN Notices.) Trial version Fri Aug 28 13:14:29 1992 Doug Lea (dl at g.oswego.edu) * Based loosely on libg++-1.2X malloc. (It retains some of the overall structure of old version, but most details differ.) */ libffi-3.2.1/src/debug.c0000664000175000017500000000455512427410334011725 00000000000000/* ----------------------------------------------------------------------- debug.c - Copyright (c) 1996 Red Hat, Inc.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Check the libffi web page for updates: . What is libffi? =============== Compilers for high level languages generate code that follow certain conventions. These conventions are necessary, in part, for separate compilation to work. One such convention is the "calling convention". The "calling convention" is essentially a set of assumptions made by the compiler about where function arguments will be found on entry to a function. A "calling convention" also specifies where the return value for a function is found. Some programs may not know at the time of compilation what arguments are to be passed to a function. For instance, an interpreter may be told at run-time about the number and types of arguments used to call a given function. Libffi can be used in such programs to provide a bridge from the interpreter program to compiled code. The libffi library provides a portable, high level programming interface to various calling conventions. This allows a programmer to call any function specified by a call interface description at run time. FFI stands for Foreign Function Interface. A foreign function interface is the popular name for the interface that allows code written in one language to call code written in another language. The libffi library really only provides the lowest, machine dependent layer of a fully featured foreign function interface. A layer must exist above libffi that handles type conversions for values passed between the two languages. Supported Platforms =================== Libffi has been ported to many different platforms. For specific configuration details and testing status, please refer to the wiki page here: http://www.moxielogic.org/wiki/index.php?title=Libffi_3.2 At the time of release, the following basic configurations have been tested: |-----------------+------------------+-------------------------| | Architecture | Operating System | Compiler | |-----------------+------------------+-------------------------| | AArch64 (ARM64) | iOS | Clang | | AArch64 | Linux | GCC | | Alpha | Linux | GCC | | Alpha | Tru64 | GCC | | ARC | Linux | GCC | | ARM | Linux | GCC | | ARM | iOS | GCC | | AVR32 | Linux | GCC | | Blackfin | uClinux | GCC | | HPPA | HPUX | GCC | | IA-64 | Linux | GCC | | M68K | FreeMiNT | GCC | | M68K | Linux | GCC | | M68K | RTEMS | GCC | | M88K | OpenBSD/mvme88k | GCC | | Meta | Linux | GCC | | MicroBlaze | Linux | GCC | | MIPS | IRIX | GCC | | MIPS | Linux | GCC | | MIPS | RTEMS | GCC | | MIPS64 | Linux | GCC | | Moxie | Bare metal | GCC | | Nios II | Linux | GCC | | OpenRISC | Linux | GCC | | PowerPC 32-bit | AIX | IBM XL C | | PowerPC 64-bit | AIX | IBM XL C | | PowerPC | AMIGA | GCC | | PowerPC | Linux | GCC | | PowerPC | Mac OSX | GCC | | PowerPC | FreeBSD | GCC | | PowerPC 64-bit | FreeBSD | GCC | | PowerPC 64-bit | Linux ELFv1 | GCC | | PowerPC 64-bit | Linux ELFv2 | GCC | | S390 | Linux | GCC | | S390X | Linux | GCC | | SPARC | Linux | GCC | | SPARC | Solaris | GCC | | SPARC | Solaris | Oracle Solaris Studio C | | SPARC64 | Linux | GCC | | SPARC64 | FreeBSD | GCC | | SPARC64 | Solaris | Oracle Solaris Studio C | | TILE-Gx/TILEPro | Linux | GCC | | VAX | OpenBSD/vax | GCC | | X86 | FreeBSD | GCC | | X86 | GNU HURD | GCC | | X86 | Interix | GCC | | X86 | kFreeBSD | GCC | | X86 | Linux | GCC | | X86 | Mac OSX | GCC | | X86 | OpenBSD | GCC | | X86 | OS/2 | GCC | | X86 | Solaris | GCC | | X86 | Solaris | Oracle Solaris Studio C | | X86 | Windows/Cygwin | GCC | | X86 | Windows/MingW | GCC | | X86-64 | FreeBSD | GCC | | X86-64 | Linux | GCC | | X86-64 | Linux/x32 | GCC | | X86-64 | OpenBSD | GCC | | X86-64 | Solaris | Oracle Solaris Studio C | | X86-64 | Windows/Cygwin | GCC | | X86-64 | Windows/MingW | GCC | | Xtensa | Linux | GCC | |-----------------+------------------+-------------------------| Please send additional platform test results to libffi-discuss@sourceware.org and feel free to update the wiki page above. Installing libffi ================= First you must configure the distribution for your particular system. Go to the directory you wish to build libffi in and run the "configure" program found in the root directory of the libffi source distribution. If you're building libffi directly from version control, configure won't exist yet; run ./autogen.sh first. You may want to tell configure where to install the libffi library and header files. To do that, use the --prefix configure switch. Libffi will install under /usr/local by default. If you want to enable extra run-time debugging checks use the the --enable-debug configure switch. This is useful when your program dies mysteriously while using libffi. Another useful configure switch is --enable-purify-safety. Using this will add some extra code which will suppress certain warnings when you are using Purify with libffi. Only use this switch when using Purify, as it will slow down the library. It's also possible to build libffi on Windows platforms with Microsoft's Visual C++ compiler. In this case, use the msvcc.sh wrapper script during configuration like so: path/to/configure CC=path/to/msvcc.sh CXX=path/to/msvcc.sh LD=link CPP="cl -nologo -EP" For 64-bit Windows builds, use CC="path/to/msvcc.sh -m64" and CXX="path/to/msvcc.sh -m64". You may also need to specify --build appropriately. It is also possible to build libffi on Windows platforms with the LLVM project's clang-cl compiler, like below: path/to/configure CC="path/to/msvcc.sh -clang-cl" CXX="path/to/msvcc.sh -clang-cl" LD=link CPP="clang-cl -EP" When building with MSVC under a MingW environment, you may need to remove the line in configure that sets 'fix_srcfile_path' to a 'cygpath' command. ('cygpath' is not present in MingW, and is not required when using MingW-style paths.) For iOS builds, the 'libffi.xcodeproj' Xcode project is available. Configure has many other options. Use "configure --help" to see them all. Once configure has finished, type "make". Note that you must be using GNU make. You can ftp GNU make from ftp.gnu.org:/pub/gnu/make . To ensure that libffi is working as advertised, type "make check". This will require that you have DejaGNU installed. To install the library and header files, type "make install".

The developers of the GNU Compiler Collection project have made innumerable valuable contributions. See the ChangeLog file for details. Some of the ideas behind libffi were inspired by Gianni Mariani's free gencall library for Silicon Graphics machines. The closure mechanism was designed and implemented by Kresten Krab Thorup. Major processor architecture ports were contributed by the following developers: aarch64 Marcus Shawcroft, James Greenhalgh alpha Richard Henderson arm Raffaele Sena blackfin Alexandre Keunecke I. de Mendonca cris Simon Posnjak, Hans-Peter Nilsson frv Anthony Green ia64 Hans Boehm m32r Kazuhiro Inaoka m68k Andreas Schwab m88k Miod Vallat microblaze Nathan Rossi mips Anthony Green, Casey Marshall mips64 David Daney moxie Anthony Green nios ii Sandra Loosemore openrisc Sebastian Macke pa Randolph Chung, Dave Anglin, Andreas Tobler powerpc Geoffrey Keating, Andreas Tobler, David Edelsohn, John Hornkvist powerpc64 Jakub Jelinek s390 Gerhard Tonn, Ulrich Weigand sh Kaz Kojima sh64 Kaz Kojima sparc Anthony Green, Gordon Irlam tile-gx/tilepro Walter Lee vax Miod Vallat x86 Anthony Green, Jon Beniston x86-64 Bo Thorsen xtensa Chris Zankel Jesper Skov and Andrew Haley both did more than their fair share of stepping through the code and tracking down bugs. Thanks also to Tom Tromey for bug fixes, documentation and configuration help. Thanks to Jim Blandy, who provided some useful feedback on the libffi interface. Andreas Tobler has done a tremendous amount of work on the testsuite. Alex Oliva solved the executable page problem for SElinux. The list above is almost certainly incomplete and inaccurate.

See # the libtool manual to understand the meaning of the fields. This is # a separate file so that version updates don't involve re-running # automake. # # Here are a set of rules to help you update your library version # information: # # 1. Start with version information of `0:0:0' for each libtool library. # # 2. Update the version information only immediately before a public # release of your software. More frequent updates are unnecessary, # and only guarantee that the current interface number gets larger # faster. # # 3. If the library source code has changed at all since the last # update, then increment revision (`c:r:a' becomes `c:r+1:a'). # # 4. If any interfaces have been added, removed, or changed since the # last update, increment current, and set revision to 0. # # 5. If any interfaces have been added since the last public release, # then increment age. # # 6. If any interfaces have been removed since the last public # release, then set age to 0. # # CURRENT:REVISION:AGE 6:4:0 libffi-3.2.1/ChangeLog.libffi0000664000175000017500000004732612427410334012713

Future changelogs will come from git, with autogenerated snapshots shipped in distributed tarballs. 2014-03-16 Josh Triplett Add support for stdcall, thiscall, and fastcall on non-Windows x86-32. Linux supports the stdcall calling convention, either via functions explicitly declared with the stdcall attribute, or via code compiled with -mrtd which effectively makes stdcall the default. This introduces FFI_STDCALL, FFI_THISCALL, and FFI_FASTCALL on non-Windows x86-32 platforms, as non-default calling conventions. * Makefile.am: Compile in src/x86/win32.S on non-Windows x86-32. * src/x86/ffitarget.h: Add FFI_STDCALL, FFI_THISCALL, and FFI_FASTCALL on non-Windows x86-32. Increase trampoline size to accomodate these calling conventions, and unify some ifdeffery. * src/x86/ffi.c: Add support for FFI_STDCALL, FFI_THISCALL, and FFI_FASTCALL on non-Windows x86-32 platforms; update ifdeffery. * src/x86/win32.S: Support compiling on non-Windows x86-32 platforms. On those platforms, avoid redefining the SYSV symbols already provided by src/x86/sysv.S. * testsuite/libffi.call/closure_stdcall.c: Run on non-Windows. #define __stdcall if needed. * testsuite/libffi.call/closure_thiscall.c: Run on non-Windows. #define __fastcall if needed. * testsuite/libffi.call/fastthis1_win32.c: Run on non-Windows. * testsuite/libffi.call/fastthis2_win32.c: Ditto. * testsuite/libffi.call/fastthis3_win32.c: Ditto. * testsuite/libffi.call/many2_win32.c: Ditto. * testsuite/libffi.call/many_win32.c: Ditto. * testsuite/libffi.call/strlen2_win32.c: Ditto. * testsuite/libffi.call/strlen_win32.c: Ditto. * testsuite/libffi.call/struct1_win32.c: Ditto. * testsuite/libffi.call/struct2_win32.c: Ditto. 2014-03-16 Josh Triplett * prep_cif.c: Remove unnecessary ifdef for X86_WIN32. ffi_prep_cif_core had a special case for X86_WIN32, checking for FFI_THISCALL in addition to the FFI_FIRST_ABI-to-FFI_LAST_ABI range before returning FFI_BAD_ABI. However, on X86_WIN32, FFI_THISCALL already falls in that range, making the special case unnecessary. Remove it. 2014-03-16 Josh Triplett * testsuite/libffi.call/closure_stdcall.c, testsuite/libffi.call/closure_thiscall.c: Remove fragile stack pointer checks. These files included inline assembly to save the stack pointer before and after the call, and compare the values. However, compilers can and do leave the stack in different states for these two pieces of inline assembly, such as by saving a temporary value on the stack across the call; observed with gcc -Os, and verified as spurious through careful inspection of disassembly. 2014-03-16 Josh Triplett * testsuite/libffi.call/many.c: Avoid spurious failure due to excess floating-point precision. * testsuite/libffi.call/many_win32.c: Ditto. 2014-03-16 Josh Triplett * libtool-ldflags: Re-add. 2014-03-16 Josh Triplett * Makefile.in, aclocal.m4, compile, config.guess, config.sub, configure, depcomp, include/Makefile.in, install-sh, libtool-ldflags, ltmain.sh, m4/libtool.m4, m4/ltoptions.m4, m4/ltsugar.m4, m4/ltversion.m4, m4/lt~obsolete.m4, man/Makefile.in, mdate-sh, missing, testsuite/Makefile.in: Delete autogenerated files from version control. * .gitignore: Add autogenerated files. * autogen.sh: New script to generate the autogenerated files. * README: Document requirement to run autogen.sh when building directly from version control. * .travis.yml: Run autogen.sh 2014-03-14 Anthony Green * configure, Makefile.in: Rebuilt. 2014-03-10 Mike Hommey * configure.ac: Allow building for mipsel with Android NDK r8. * Makefile.am (AM_MAKEFLAGS): Replace double quotes with single quotes. 2014-03-10 Landry Breuil * configure.ac: Ensure the linker supports @unwind sections in libffi. 2014-03-01 Anthony Green * Makefile.am (EXTRA_DIST): Replace old scripts with generate-darwin-source-and-headers.py. * Makefile.in: Rebuilt. 2014-02-28 Anthony Green * Makefile.am (AM_CFLAGS): Reintroduce missing -DFFI_DEBUG for --enable-debug builds. * Makefile.in: Rebuilt. 2014-02-28 Makoto Kato * src/closures.c: Fix build failure when using clang for Android. 2014-02-28 Marcin Wojdyr * libffi.pc.in (toolexeclibdir): use -L${toolexeclibdir} instead of -L${libdir}. 2014-02-28 Paulo Pizarro * src/bfin/sysv.S: Calling functions in shared libraries requires considering the GOT. 2014-02-28 Josh Triplett * src/x86/ffi64.c (classify_argument): Handle case where FFI_TYPE_LONGDOUBLE == FFI_TYPE_DOUBLE. 2014-02-28 Anthony Green * ltmain.sh: Generate with libtool-2.4.2.418. * m4/libtool.m4, m4/ltoptions.m4, m4/ltversion.m4: Ditto. * configure: Rebuilt. 2014-02-28 Dominik Vogt * configure.ac (AC_ARG_ENABLE struct): Fix typo in help message.

Clang clean-ups for ARM_FUNC_START. * generate-osx-source-and-headers.py: Remove. * build-ios.sh: Remove. * libffi.xcodeproj/project.pbxproj: Rebuild targets. Include x86_64+aarch64 pieces in library. Export headers properly. * src/x86/ffi64.c: More Clang warning clean-ups. * src/closures.c (open_temp_exec_file_dir): Use size_t. * src/prep_cif.c (ffi_prep_cif_core): Cast ALIGN result. * src/aarch64/sysv.S: Use CNAME for global symbols. Only use .size for ELF targets. * src/aarch64/ffi.c: Clean up for double == long double. Clean up from Clang warnings. Use Clang cache invalidation builtin. Use size_t in place of unsigned in many places. Accommodate for differences in Apple AArch64 ABI. 2013-12-02 Daniel Rodríguez Troitiño * generate-darwin-source-and-headers.py: Clean up, modernize, merged version of previous scripts. 2013-11-21 Anthony Green * configure, Makefile.in, include/Makefile.in, include/ffi.h.in, man/Makefile.in, testsuite/Makefile.in, fficonfig.h.in: Rebuilt. 2013-11-21 Alan Modra * Makefile.am (EXTRA_DIST): Add new src/powerpc files.

The raw API is designed to bypass some of the argument packing and unpacking on architectures for which it can be avoided. The closure API allows interpreted functions to be packaged up inside a C function pointer, so that they can be called as C functions, with no understanding on the client side that they are interpreted. It can also be used in other cases in which it is necessary to package up a user specified parameter and a function pointer as a single function pointer. The closure API must be implemented in order to get its functionality, e.g. for use by gij. Routines are provided to emulate the raw API if the underlying platform doesn't allow faster implementation. More details on the raw and cloure API can be found in: http://gcc.gnu.org/ml/java/1999-q3/msg00138.html and http://gcc.gnu.org/ml/java/1999-q3/msg00174.html -------------------------------------------------------------------- */ #ifndef LIBFFI_H #define LIBFFI_H #ifdef __cplusplus extern "C" { #endif /* Specify which architecture libffi is configured for. */ #ifndef @TARGET@ #define @TARGET@ #endif /* ---- System configuration information --------------------------------- */ #include #ifndef LIBFFI_ASM #if defined(_MSC_VER) && !defined(__clang__) #define __attribute__(X) #endif #include #include /* LONG_LONG_MAX is not always defined (not if STRICT_ANSI, for example).

(http://opencores.org/or1k/Main_Page) This patch has been tested under Linux with QEMU-user emulation support. - 32 Bit - big endian - delayed instructions This is the only available configuration under Linux. The description of the ABI can be found on the official website. Is passes the testsuite except of the unwindtest_ffi_call.cc testcase, which seems to be a problem of gcc and not libffi. Some testcases of the gcc testsuite still fail.

If the O_TMPFILE flag is not defined (old Linux kernel or libc) the behavior is unchanged. The open_temp_exec_file_name function now need a new argument "flags" (like O_CLOEXEC) used for temporary file creation. The O_TMPFILE flag allow temporary file creation without race condition. This feature/fix prevent another process to access the (future) executable file from the file system. The O_CLOEXEC flag automatically close the temporary file for any execve. This avoid transmitting (executable) file descriptor to a child process. commit 0403f332b1f478696c30d3d8a0e2f6eef24aaf88 Author: Anthony Green Date: Mon May 19 09:41:32 2014 -0400 Update date.

For example, a -mlong-double-128 libffi can be used with -mlong-double-64 code. Using the return value area as a place to pass parameters wasn't such a good idea, causing a failure of cls_ulonglong.c. I didn't see this when running the mainline gcc libffi testsuite because that version of the test is inferior to the upstreamm libffi test. Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant that a parameter save area could be allocated before it was strictly necessary. Wrong but harmless.

ELFv1 objects can't be linked with ELFv2 objects, so this is one case where preprocessor tests in ffi.c are fine. Also, there is no need to define a new FFI_ELFv2 or somesuch value in enum ffi_abi. FFI_LINUX64 will happily serve both ABIs. commit 362851379a49ce07d3e36e82c4e5c7b6cc16a352 Author: Alan Modra Date: Sat Nov 16 06:52:43 2013 -0500 Andreas' 2013-02-08 change reverted some breakage for struct return values from 2011-11-12, but in so doing reintroduced string instructions to sysv.S that are not supported on all powerpc variants. This patch properly copies the bounce buffer to destination in C code rather than in asm. I have tested this on powerpc64-linux, powerpc-linux and powerpc-freebsd. Well, the last on powerpc-linux by lying to configure with CC="gcc -m32 -msvr4-struct-return -mlong-double-64" \ CXX="g++ -m32 -msvr4-struct-return -mlong-double-64" \ /src/libffi-current/configure --build=powerpc-freebsd and then make && make CC="gcc -m32" CXX="g++ -m32" \ RUNTESTFLAGS=--target_board=unix/-m32/-msvr4-struct-return/-mlong-double-64\ check commit 1c06515d927d9de1582438d4eb5953890e79c5c7 Author: Alan Modra Date: Sat Nov 16 06:41:36 2013 -0500 The powerpc64 ABIs align structs passed by value, a fact ignored by gcc for quite some time. Since gcc now does the correct alignment, libffi needs to follow suit. This ought to be made selectable via a new abi value, and the #ifdefs removed from ffi.c along with many other #ifdefs present there and in assembly. I'll do that with a followup patch sometime. This is a revised version of https://sourceware.org/ml/libffi-discuss/2013/msg00162.html commit a97cf1fae575d8bfd5259c5c422025ad43911326 Author: Alan Modra Date: Sat Nov 16 06:40:13 2013 -0500 This patch prepares for ELFv2, where sizes of these areas change. It also makes some minor changes to improve code efficiency. commit 164283f4ac5972ce2ab5e015cc2ab1014c23276c Author: Alan Modra Date: Sat Nov 16 06:38:55 2013 -0500 The powerpc64 support opted to pass floating point values both in the fpr area and the parameter save area, necessary when the backend doesn't know if a function argument corresponds to the ellipsis arguments of a variadic function. This patch adds powerpc support for variadic functions, and changes the code to only pass fp in the ABI mandated area. ELFv2 needs this change since the parameter save area may not exist there. This also fixes two faulty tests that used a non-variadic function cast to call a variadic function, and spuriously reasoned that this is somehow necessary for static functions.. commit 31257b3189f81a199bc2902c22bc5f2d7c54ccde Author: Andrew Haley Date: Sat Nov 16 06:35:51 2013 -0500 Fix sample closure code commit db0ace3a38496af73eae3df02ef353736d16909f Author: Andrew Haley Date: Sat Nov 16 06:29:25 2013 -0500 Fix broken test cases commit de10f5039ed7a53382ddcc95c368d03e535edb98 Merge: 58c2577 f3657da Author: Anthony Green Date: Thu Nov 14 10:56:29 2013 -0500 Merge branch 'master' of https://github.com/bivab/libffi Conflicts: ChangeLog commit f3657da278dd63afcdd8762894a9bdaea8ef028a Author: David Schneider Date: Thu Nov 14 13:02:16 2013 +0100 update Changelog commit 58c2577a3ff80e7416ef0434769e2af23365719c Author: Alan Modra Date: Wed Nov 13 16:55:36 2013 -0500 This enshrines the current testsuite practice of using ffi_arg for returned values.

This implements support for re-mapping a shared table of executable trampolines directly in front of a writable configuration page, working around PROT_WRITE restrictions for sandboxed applications on Apple's iOS. This implementation is for testing purposes; a proper allocator is still necessary, and ARM-specific code needs to be moved out of src/closures.c. commit f38364b399184e682fc3e785084bd497827bc5af Author: Landon Fuller Date: Sun Sep 19 10:42:36 2010 -0700 Fix symbol prefix for ffi_closure_SYSV_inner on Darwin. commit 36849e7716b77aa25e4175d1f4be1b93dbf47aac Author: Landon Fuller Date: Sun Sep 19 09:35:04 2010 -0700 Whitespace/comment fixes. commit b764162526854686e579a48b6ac5981f4eb886a3 Author: Landon Fuller Date: Sun Sep 19 09:04:34 2010 -0700 Fix the script name (build-iphone.sh -> build-ios.sh) commit a3d9aa85013341451ea97766485b7a11852d32b2 Author: Landon Fuller Date: Sun Sep 19 09:03:52 2010 -0700 Update the autogenerated autoconf/automake files. commit c71480eaf839f26bbdfcd8965f65ac4d8defddc0 Author: Landon Fuller Date: Sun Sep 19 09:02:05 2010 -0700 Update automake/autoconf to conditionally build src/arm/trampoline.S if FFI_EXEC_TRAMPOLINE_TABLE is enabled. commit 9af9291b73bc5e27ecd949bec8157f20426d65b8 Author: Landon Fuller Date: Sun Sep 19 08:52:33 2010 -0700 Add the trampoline table generated by gentramp.sh commit 68ce0c383ece84f69945d1c8c3fed03f7f9cb5d6 Author: Landon Fuller Date: Sun Sep 19 08:38:19 2010 -0700 Add a shell script that generates the ARM trampoline page. This generates a page of 340 trampolines, aligned within one page. The trampolines use pc-relative addressing to reference config data (context, jump address) from a page placed directly prior to the trampoline page. This can be used on systems -- such as iOS -- that do not support writable, executable memory by remapping the executable page containing the trampolines directly above a newly allocated writable config page. commit 75af086be8830a8eafe9b1ebda199d788bcb0c62 Author: Landon Fuller Date: Sat Sep 18 18:12:19 2010 -0700 Update autoconf files commit 1ac92cca9b02ef8d6a769f0de1adccd5c9630355 Author: Landon Fuller Date: Sat Sep 18 18:08:14 2010 -0700 Add autoconf check for W^X platforms that require a trampoline table.

On iOS, we must use the AAPCS floating point return value calling conventions. libffi's ARM implementation will only use these conventions if __SOFTFP__ is defined, which is not the case when GCC's -mfloat-abi defaults to 'softfp' instead of 'soft'. To work around this we manually define __SOFTFP__ for Apple platforms in the ARM-specific sysv.S.
