Josh Triplett b5fed60194 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.)

Fix 64-bit Windows support
 2014-03-25 16:12:17 -04:00
Josh Triplett be50b87a49 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 56be47f876 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 48a8eda74a Avoid referencing undefined ABIs on 64-bit Windows builds 
64-bit Windows does not have FFI_STDCALL, FFI_THISCALL, or FFI_FASTCALL.

Josh Triplett f0f4138f90 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 ef5890ebaf 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 4fca48901e 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 2087dcf736 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 e1911f78df 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 9531d05f64 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.
