d4640608 | 2018-03-18 07:00:42 | Fully allocate file backing writable maps (#389) When ftruncate() is used on a filesystem supporting sparse files, space in the file is not actually allocated. Then, when the file is mmap'd and libffi writes to the mapping, SIGBUS is thrown to the calling application. Instead, always fully allocate the file that will back writable maps. | |

b58caef7 | 2018-02-17 19:00:40 | ia64: fix small struct return This change fixes libffi.call/struct10.c failure on ia64: FAIL: libffi.call/struct10.c -W -Wall -Wno-psabi -O0 execution test .Lst_small_struct handles returns for structs less than 32 bytes (following ia64 return value ABI [1]). Subroutine does roughly the following: ``` mov [sp+0] = r8 mov [sp+8] = r9 mov [sp+16] = r10 mov [sp+24] = r11 memcpy(destination, source=sp, 12); ``` The problem: ia64 ABI guarantees that top 16 bytes of stack are scratch space for callee function. Thus it can clobber it. [1] says (7.1 Procedure Frames): """ * Scratch area. This 16-byte region is provided as scratch storage for procedures that are called by the current procedure. Leaf procedures do not need to allocate this region. A procedure may use the 16 bytes at the top of its own frame as scratch memory, but the contents of this area are not preserved by a procedure call. """ In our case 16 top bytes are clobbered by a PLT resolver when memcpy() is called for the first time. As a result memcpy implementation reads already clobbered data frop top of stack. The fix is simple: allocate 16 bytes of scrats space prior to memcpy() call.

11de69dd | 2018-02-11 11:29:39 | ia64: fix variadic function closures with FP arguments libffi test framework already flagged failures as: ``` FAIL: libffi.call/cls_double_va.c -W -Wall -Wno-psabi -O0 output pattern test, is 7.0 res: 4 0.0 res: 4 ? should match 7.0 ?es: 4 ?.0 res: 4 ``` Failure happens here at ```c // testsuite/libffi.call/cls_double_va.c ... char* format = "%.1f\n"; double doubleArg = 7; ... CHECK(ffi_prep_closure_loc(pcl, &cif, cls_double_va_fn, NULL, code) == FFI_OK); res = ((int(*)(char*, ...))(code))(format, doubleArg); ``` libffi expects 'doubleArg' to be located in 'f9' (second FP argument) but gcc placed it to 'r33' (second GR). ia64 software [1] manual described argument passing ABI in "8.5.2 Register Parameters" as: """ If an actual parameter is known to correspond to a floating-point formal parameter, the following rules apply: a) The actual parameter is passed in the next available floating-point parameter register, if one is available. Floating-point parameter registers are allocated as needed from the range f8-f15, starting with f8. b) If all available floating-point parameter registers have been used, the actual parameter is passed in the appropriate general register(s). (This case can occur only as a result of homogeneous floating-point aggregates, described below.) If a floating-point actual parameter is known to correspond to a variable-argument specification in the formal parameter list, the following rule applies: c) The actual parameter is passed in the appropriate general register(s). If the compiler cannot determine, at the point of call, whether the corresponding formal parameter is a varargs parameter, it must generate code that satisfies both of the above conditions. (The compiler’s determination may be based on prototype declarations, language standard assumptions, analysis, or other user options or information.) """ We have [c] case here and gcc uses only GR for parameter passing. The change binds known variadic arguments ro GRs instead of FPs as those are always expected to be initialized for all variadic call types.

3c372c38 | 2017-10-24 13:53:56 | arm: fix a level of indirection issue Rather than relying on the stack being 0'ed out always, do it manually. The stack generally happened to be zero, and because the compiler realizes that the tests are dealing with chars truncates the read value. However, the top 3 nibbles of the value are undefined and may be non-zero. The indirection level caused a null-pointer dereference. Explicitly scribbling on the stack during the allocation causes test failures without the original zexting behaviour. | |

7ad0ae7f | 2017-10-10 11:44:05 | arm: zext return value parameters The closure function (invoked as closure->fun in ffi_closure_XXX_inner) will only populate the actual number of bytes for the true return type, which may be a character. This leaves garbage on the stack when the assembly closure function (i.e. ffi_closure_XXX) reads the return value off of the stack into r0 as a 4-byte value. ffi_closure_XXX always leaves room for at least 4 bytes here, so we can safely set them to 0. Otherwise, if there is garbage in any of these bytes, these end up in r0 and in the returned value as well. | |

43fc5bca | 2015-08-03 23:34:05 | Correct powerpc sysv stack argument accounting ppc32 starts using the stack for integer arg passing when we run out of integer arg passing registers. Similarly, we start using the stack for floating point args when we run out of floating point registers. The decision on where an integer arg goes does not depend on number of floating point args, nor does the decision on where a floating point arg goes depend on number of integer args. Alignment of stack args also simply depends on number of stack args. This patch untangles the horrible mess we had, with intarg_count being wrongly used to count both integer args and stack words. * src/powerpc/ffi_sysv.c (ffi_prep_cif_sysv_core): Count fprs, gprs, and stack words separately.

This allows libffi compiled on a 64-bit x86 platform to call EFI functions. Compile in ffiw64.c and win64.S on all X86_64 platforms.

c8e82d9f | 2015-07-26 16:18:57 | src/x86/win64.S: Support compiling on non-WIN64 platforms Non-WIN64 versions of the GNU assembler don't support the .seh_* directives for structured exception handling, so wrap them in a macro that compiles to nothing. Handle the registers used for the non-Windows x86-64 calling convention when on a non-Windows platform. Distinguish between cases that should refer to the native argument registers (defined as arg0, arg1, arg2, and arg3) and cases that should always refer to the Windows argument registers. | |

b740ab7c | 2015-01-16 11:32:23 | sparc: Solaris fixes * /bin/as requires .type fn,#function instead of @function. * /bin/as doesn't support .macro/.endm. I'm using preprocessor macros instead to implement E in src/sparc/v[89].S. | |

f1560b7b | 2015-01-16 11:31:37 | x86: Solaris fixes * Solaris/x86 /bin/as doesn't support .org, so I've just disabled the uses in src/x86/{sysv, unix64}.S, as on Darwin. * Solaris/x86 needs to use EH_FRAME_FLAGS so manually and compiler generated .eh_frame sections match, otherwise libffi.so fails to link: * Solaris/x86 /bin/as has different COMDAT syntax; I've disabled it for the moment. | |
