Richard Henderson 3ac1610aa3 x86: Fix cygwin32 build 
The section syntax is just that little bit different.
 2015-01-19 20:48:40 +01:00
Rainer Orth f1560b7bbe 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.

Richard Henderson f27c4e4673 x86: Fix thinko in ffi_raw_call 
Missed structure initialization for raw path.
Apparently there are no tests for this outside gcc.

Richard Henderson 3fa5d70cbb x86: Avoid fastcall when building with pcc 
Apparently, PCC doesn't support the fastcall calling convention.
Nor does it issue a warning or error for the attribute that it
does not understand.

Richard Henderson b7f6d7aa9b x86: Reinstate hand-written unwind info for sysv.S 2015-01-05 10:01:38 -08:00
Richard Henderson 6cedf81ca7 x86: Expand FFI_GO_CLOSURE 
If we're going to have to hand-write unwind info for darwin,
these macros make the job harder.
 2015-01-05 10:01:38 -08:00
Iain Sandoe ae842a515b x86: More Darwin unwind fixups 
EHFrame{N} IIRC is a special cue to ld64 that it should treat the unwind
in the object as "special/legacy" .. [these days everything is .cfi_xxxx
(except, cctools-as, as you noted)] .. without that much confusion arises
with ld64's atom-isation of the eh_frame section.

xxxx.eh labels are not needed for darwin ld64 >= 85.2.1 (i.e. darwin9,
xcode 3.1.4) to all intents and purposes, that's all that matters now,
since I think that anyone trying to build on 10.4/darwin8/xcode2.5 would
have to use a later ld64 (from odcctools) for other reasons.
 2015-01-05 10:01:38 -08:00
Richard Henderson 8fa3c9f24b x86: Reinstate hand-written unwind info for unix64.S 
One more try to get default Darwin to work.
 2015-01-05 10:01:37 -08:00
Richard Henderson 5f35e0ffcc x86: Avoid using gas local labels 
Which are unsupported by Darwin cctools as.
Thankfully this doesn't uglify the source too much.
 2015-01-05 10:01:37 -08:00
Richard Henderson ed1ca2777c x86: Remove use of .cfi_escape 
The unwind info isn't 100% correct at all points during the epilogue,
and not annotating is just as incorrect as the annotation.  This works
better on systems that do not support DW_OP_call_frame_cfa.

Richard Henderson 1b12593d7e x86: Honor alignment of arguments 
Darwin aligns long-double to 16, and thus all of the long double
tests were failing due to not honoring that.  We ought to be able
to devise a test case for GCC using __attribute__((aligned)) that
would have failed too.
 2015-01-05 10:01:37 -08:00
Richard Henderson 042b8dafee x86: Use .balign not .align 
The Apple assembler defaults to power of two alignment, rather than
byte alignment like everyone else.  Force byte alignment by using
the proper directive.

Richard Henderson 2f65246968 x86: Handle void arguments as if an empty structure 
Since libffi currently doesn't allow empty structures, libgo
currently maps them to ffi_type_void.  Given that we'll abort
on this case, handle it gracefully.

Richard Henderson b21ec1ce78 x86: Rewrite closures 
Move everything into sysv.S, removing win32.S and freebsd.S.
Handle all abis with a single ffi_closure_inner function.
Move complexity of the raw THISCALL trampoline into assembly
instead of the trampoline itself.
Only push the context for the REGISTER abi; let the rest
receive it in a register.
 2014-11-12 09:15:54 +01:00
Richard Henderson b9ac94f3af x86: Rewrite ffi_call 
Decouple the assembly from FFI_TYPE_*.  Merge prep_args with ffi_call,
passing the frame and the stack to the assembly.

Note that this patch isn't really standalone, as this breaks closures.

Richard Henderson e7b0056d60 x86: Force FFI_TYPE_LONGDOUBLE different from FFI_TYPE_DOUBLE 
There are few abis that set double = long double.  Eliminate the
conditional compilation and let this code simply be unused there.
 2014-11-12 09:15:35 +01:00
Richard Henderson 4b2fad8fd5 x86: Remove some conditional compilation 
Removal of ifdefs made possible to due to ffi_abi unification.
 2014-11-12 09:15:35 +01:00
Richard Henderson ef76205647 x86: Tidy ffi_abi 
The x86_64 unix port only handles one ABI; don't define all of the
other symbols.  The UNIX64 symbol retains the same value.

The i386 ports ought to have the same symbols, even if we can't yet
unify the values without incrementing the libffi soname.

We can better support structure returns, and as prep for
complex types.

Richard Henderson 99db4d42ac win64: Rewrite 
It's way too different from the 32-bit ABIs with which it is
currently associated. As seen from all of the existing XFAILs.
 2014-11-12 09:15:35 +01:00
Richard Henderson 6b62fb4a26 x86-64: Support go closures 
Dumps all of the hand-coded unwind info for gas generated.  Move jump
table data into .rodata.  Adjust ffi_call_unix64 to load the static
chain.  Split out sse portions of ffi_closure_unix64 to
ffi_closure_unix64_sse rather than test cif->flags at runtime.

Josh Triplett d36952273d Support fastcall closures 
libffi on 32-bit x86 now supports closures for all supported ABIs.
Thus, rewrite the last remaining duplicated-by-ABI test (closure_stdcall
