* Add MSYS configuration files (#728)Hans2022-09-177-30/+42
| | | | | | | | | | | | | | | | | | | | | | | | | * 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/+5
| | | | | | | | | | 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.

* static trampoline for LoongArch (#723)Xi Ruoyao2022-07-212-4/+59
| | | | | | | For the benefit and technical details of static trampoline, see https://github.com/libffi/libffi/pull/624. As a new architecture, let's be "safer" from the start. The change survived libffi testsuite on loongarch64-linux-gnu.

It's enough to get libffi build on powerpc64.

* x86-64: Always double jump table slot size for CET (#710) (#711)hjl-tools2022-05-151-6/+5
| | | | | | | | | | | | | | | | When CET is enabled, double jump table slot size to add 4 bytes of ENDBR64 for CET. Since CET enabled clang doesn't have the LLVM assembler bug: https://bugs.llvm.org/show_bug.cgi?id=21501 fixed by commit 04d39260d64e08b8bfb3844109ad43d4055b2e8d Author: Rafael Espindola <rafael.espindola@gmail.com> Date: Wed Nov 4 23:50:29 2015 +0000 Simplify .org processing and make it a bit more powerful. we can use .org to allocate jump table slot size to 16 bytes.

* Xtensa cleanups and XEA3 support (#677)Max Filippov2022-02-203-24/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * xtensa: clean up stack usage in ffi_trampoline call Space for outgoing call arguments reserved in the stack frame of the function ffi_trampoline overlaps register spill overflow area at the top of the frame. In xtensa XEA2 exception architecture the layout of overlapping areas is identical so that even if the ffi_trampoline registers frame gets spilled the memory contents doesn't change. This is not so with the xtensa XEA3 exception architecture, where registers a0 - a7 of a different function are spilled in that location. Reserve spill area for 8 registers to avoid overlapping of the spill area with the outgoing call arguments area in the ffi_trampoline. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> * xtensa: support xtensa XEA3 exception architecture XEA3 requires that 32 bytes of register spill area is reserved in all functions. Fix ffi_cacheflush entry instruction to satisfy this requirement. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> * xtensa: maintain stack alignment xtensa ABI requires stack alignment on 16 byte boundary and passing up to 6 arguments in registers. To simplify stack alignment maintenance fixed amount of stack space is reserved for arguments passed in registers and variable but correctly aligned amount is reserved for the remaining arguments. After copying arguments to the stack and loading registers the fixed part of the stack reservation is freed. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> * xtensa: fix err_bad_abi tests Check ffi_cif::abi value in the ffi_prep_closure_loc and return FFI_BAD_ABI error if it's not one of the supported values.

* powerpc64: fix handling of homogeneous float128 structs (#689)Dan Horák2022-01-311-1/+1
| | | | | | If there is a homogeneous struct with float128 members, they should be copied to vector register save area. The current code incorrectly copies only the value of the first member, not increasing the pointer with each iteration. Fix this.
* src/x86/win64.S: Use #define instead of .macro (#665) (#669)rorth2021-12-231-7/+6
| | | | The Solaris/x86 assembler doesn't support .macro/.endm, so use #define since win64.S is passed through cpp anyway.

| | | | | | | | * src/x86/ffi64.c (classify_argument): For FFI_TYPE_STRUCT set words to number of words needed for type->size + byte_offset bytes rather than just type->size bytes. Compute pos before the loop and check total size of the structure. * testsuite/libffi.call/nested_struct12.c: New test.
