* Add MSYS configuration files (#728)Hans2022-09-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | * Add MSYS configuration files MSYS behaves very similiar to Cygwin, e.g. also __CYGWIN__ is defined. Now 'make check' passes on MSYS without extra patches. * Fix warning extra tokens at end of #endif in closures.c Extra tokens converted into a comment. Also nearby indentations corrected. * Fix missing prototype warning mkostemp() on Cygwin Cygwin requires also _GNU_SOURCE to be defined to enable mkostemp() prototype. * Fix warning label ‘out’ defined but not used in ffi functions Define same preprocessor conditions for goto and label visibility. * Fix warning label ‘out’ defined but not used and related indentations. Define same preprocessor conditions for goto and label visibility. Correct also related indentations. Co-authored-by: Hannes Müller <>
* Makefile: enable target overridings. (#661)Clément Chigot2022-09-011-0/+2
| | | | | | | | | | This patch allows target to provide extra files enabling the override of Makefile rules. This patch is not needed for libffi itself but only for GCC on AIX. The t-aix file which is here empty will be replaced in GCC repository. We cannot include GCC version directly here because it has no sense for a standalone libffi.

* Fix building for arm windows with mingw toolchains (#631)Martin Storsjö2021-04-061-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * arm: Check _WIN32 instead of _M_ARM or _MSC_VER for detecting windows This matches what was done for ARM64 in c06468fa6674d3783a0edb1d0fae9afc8bc28513. * arm: Only use armasm source when building with MSVC When building for windows/arm with clang, the normal gas style .S source works fine (if fixed up to support thumb and other windows specifics). This matches what was done for ARM64 in c06468fa6674d3783a0edb1d0fae9afc8bc28513. * arm: Fix sysv.S to work in thumb mode Align cases in jump tables (adding nop padding to make sure each case starts where expected). Rewrite instructions that add directly to the pc register. For ffi_closure_ret, factor out a call_epilogue subroutine that restores both sp and pc from the stack; the thumb version of ldm can't load into the sp register. To avoid excessive ifdeffing, keep using call_epilogue in arm mode, but keep the shorter "ldm sp, {sp, pc}" epilogue in that case. * arm: Add win32 version of trampoline to sysv.S This matches the version of it in sysv_msvc_arm32.S. The calling C code expects a specific form of the trampoline on windows; make sure these work the same on windows regardless of the form of assembly used. * arm: Avoid optimizing out clearing the thumb bit of ffi_arm_trampoline We clear the thumb bit of ffi_arm_trampoline with a bitmask before memcpying its instructions into closure->tramp. If the bit isn't cleared, the memcpy of the trampoline function copies the wrong instructions. If the ffi_arm_trampoline symbol is declared as an array of int, the compiler can assume that it is aligned to a 4 byte boundary and the bitmask operation is a no-op, and optimize it out. See https://godbolt.org/z/dE3jE1WTz; both Clang and GCC optimize out the bitmask as it is, while MSVC doesn't. By declaring the trampoline as an array of unsigned char, the bitmask works as intended.
* libffi/x86: Always check __x86_64__ for x32 hosts (#601) (#602)hjl-tools2020-12-021-16/+8
| | | | Since for x86_64-*x32 and x86_64-x32-* hosts, -m32 generates ia32 codes. We should always check __x86_64__ for x32 hosts.

* Fix building for aarch64 windows with mingw toolchains (#555)Martin Storsjö2020-04-251-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | * aarch64: Check _WIN32 instead of _M_ARM64 for detecting windows This fixes building for aarch64 with mingw toolchains. _M_ARM64 is predefined by MSVC, while mingw compilers predefine __aarch64__. In aarch64 specific code, change checks for _M_ARM64 into checks for _WIN32. In arch independent code, check for (defined(_M_ARM64) || defined(__aarch64__)) && defined(_WIN32) instead of just _M_ARM64. In src/closures.c, coalesce checks like defined(X86_WIN32) || defined(X86_WIN64) || defined(_M_ARM64) into plain defined(_WIN32). Technically, this enables code for ARM32 windows where it wasn't, but as far as I can see it, those codepaths should be fine for that architecture variant as well. * aarch64: Only use armasm source when building with MSVC When building for windows/arm64 with clang, the normal gas style .S source works fine. sysv.S and win64_armasm.S seem to be functionally equivalent, with only differences being due to assembler syntax.

| | | | | Since x32 doesn't support WIN64/EFI64, don't include it for x32. Also x32 has sizeof size_t == 4. But TARGET should be X86_64.

* Support the WIN64/EFI64 calling convention on all X86_64 platformsJosh Triplett2015-07-261-1/+1
| | | | | | | | | | | Add a new calling convention FFI_EFI64, alias FFI_WIN64, on all X86_64 platforms. 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. When compiled for a platform other than X86_WIN64, ffiw64.c suffixes its functions with _efi64, to avoid conflict with the platform's actual implementations of those functions.
