[Bug libffi/35484] New: libffi doesn't support AIX 64bit

[Laurent dot Vivier at bull dot net]

When compiling libffi on AIX with ppc64 target, libffi fails.
Assembler parts of libffi manage only 32bit AIX.

 I was trying to compile Mozilla Firefox latest build ( 3.7 a1pre) on AIX
64-bit.

      But I got a compiler/linker error while building libffi module (
https://bugzilla.mozilla.org/show_bug.cgi?id=527410 ).  I tried applying this
patch, but this did not resolve the linker error - undefined symbol
.ffi_closure_helper_DARWIN.

Adding the below lines in aix_closure.S did resolve the 'undefined symbol error
- .ffi_closure_helper_DARWIN'

# .text section
   .extern .ffi_closure_helper_DARWIN

------- Comment #10 from dominiq at lps dot ens dot fr  2009-12-03 09:50 -------
Revision 154855 (comment #5) has broken bootstrap on ppc-darwin (pr42243). This
is now fixed, but there are now ~60 new failures (see comment #2 of pr42243).
What is the best strategy to keep track of the problem:

(1) continue to use pr42243,
(2) use this pr and close pr42243 as fixed,
(3) open a new pr and close pr42243 as fixed?

Richard Guenther has closed pr42243 as fixed which only the (b) and (c)
options. After a clean bootstrap at revision 154924 and an update to 154943, I
still have the following failures:
