b740ab7cc9 sparc: Solaris fixes 
* /bin/as requires .type fn,#function instead of @function.
* /bin/as doesn't support .macro/.endm.  I'm using preprocessor macros
  instead to implement E in src/sparc/v[89].S.

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.

536366349c aarch64: implement the trampoline table workaround for ffi closures on Apple systems

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.

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.

5f35e0ffcc x86: Avoid using gas local labels 
Which are unsupported by Darwin cctools as.

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.

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.

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.

7ba30b1906 s390: Inline and tidy ffi_prep_args 
As per discussion with Ulrich Weigand, document the restrictions
on the code within ffi_call_int as we simultaneously prepare
stack frames for ffi_call_SYSV and the target function.

f69ec6f35d s390: Use pc-relative insns in 31-bit mode 
It's silly to stick to esa/390 features when the compiler won't.
Detect when brasl and larl are used by the compiler and then use
them in the assembly.

2f530de168 s390: Reorganize assembly 
Avoid using ffi_prep_args as a callback; do all the work setting
up the frame within ffi_call_int directly.  Save fewer registers
in ffi_closure_SYSV.

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.
