Ole André Vadla Ravnås a539f7ff 2014-04-06T20:53:02 Fix alignment of AArch64 assembler functions
Josh Triplett b5fed601 2014-04-05T17:33:42 Fix ABI on 32-bit non-Windows x86: go back to trampoline size 10 The trampoline size is part of the ABI, so it cannot change. Move the logic from the stdcall and thiscall trampolines to the functions they call, to reduce them both to 10 bytes. This drops the previously added support for raw THISCALL closures on non-Windows. (Non-raw THISCALL closures still work.)
Anthony Green afee5373 2014-03-25T16:12:35 Merge pull request #106 from joshtriplett/darwin-award [3.1 blocker] Update OS X build system to include win32.S on 32-bit
Anthony Green 7d247856 2014-03-25T16:12:17 Merge pull request #110 from joshtriplett/w64 Fix 64-bit Windows support
Josh Triplett be50b87a 2014-03-24T21:44:13 Always use configure to detect whether global symbols need underscores 64-bit Windows already used this check; make it universal, and use it in place of an ifdef on X86_WIN32, to handle non-Windows platforms that use the underscore, such as Darwin.
Josh Triplett 56be47f8 2014-03-24T21:24:53 Fix a warning on 64-bit Windows When sizeof(size_t) != sizeof(unsigned), adding a size_t to cif->bytes produces a "possible loss of data" warning. However, the size_t in question refers to the size of a single parameter. Use a cast to avoid the warning.
Josh Triplett 48a8eda7 2014-03-24T21:21:12 Avoid referencing undefined ABIs on 64-bit Windows builds 64-bit Windows does not have FFI_STDCALL, FFI_THISCALL, or FFI_FASTCALL.
Josh Triplett f0f4138f 2014-03-22T10:00:53 win32.S: Add handling for position-independent code on Darwin Newer versions of Darwin generate the necessary stub functions automatically and just need a call instruction, but accomodating older versions as well requires adding the stub.
Josh Triplett ef5890eb 2014-03-21T11:01:39 win32.S: Use shifting for multiplication rather than repeated addition The jump table code added a register to itself twice to multiply by 4; shift the register left by 2 instead.
Josh Triplett 4fca4890 2014-03-21T11:00:41 win32.S: Make the jump tables position-independent Now that non-Windows platforms include win32.S, it needs to support building as position-independent code. This fixes build failures on target platforms that do not allow text relocations.
Josh Triplett 2087dcf7 2014-03-21T10:57:06 win32.S: Make calls to ffi_closure_SYSV_inner position-independent Now that non-Windows platforms include win32.S, it needs to support building as position-independent code. This fixes one source of build failures on target platforms that do not allow text relocations.
Josh Triplett e1911f78 2014-03-16T03:25:53 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.
Josh Triplett 9531d05f 2014-03-16T01:50:02 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.

Alan Modra ab79d6e2 2013-11-21T06:12:35 This separates the 32-bit sysv/linux/bsd code from the 64-bit linux code, and makes it possible to link code compiled with different options to those used to compile libffi. 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. Found when splitting apart ffi.c into 32-bit and 64-bit support.

Alan Modra 16d56c51 2013-11-18T06:36:03 An #endif in the wrong place would cause compile failure on powerpcle. Using bl instead of b doesn't cause runtime failures as you might think, but does mess the processor branch prediction.
Alan Modra 83f65b63 2013-11-16T06:53:50 Finally, this adds _CALL_ELF == 2 support. 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.

Alan Modra 36285137 2013-11-16T06:52:43 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
Alan Modra 1c06515d 2013-11-16T06:41:36 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
Alan Modra a97cf1fa 2013-11-16T06:40:13 This patch prepares for ELFv2, where sizes of these areas change. It also makes some minor changes to improve code efficiency.
Alan Modra 164283f4 2013-11-16T06:38:55 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..
David Schneider 77f823e3 2013-11-13T14:26:57 stop trying to assing vfp regs once we are done with the registers
David Schneider 37067ec5 2013-11-12T19:49:01 mark all vfp registers as used when done. To avoid assigning registers the would fit, once arguments have been on the stack, we mark all registers as used once we do not find a free register for the first time.
