Check for libffi
_cv _as _x86 _pcrel should not look for just "warning"
I posted the patch upstream: http://sourceware.org/ml/libffi-discuss/2011/msg00024.html but not reply so far. The problem is that the configure for ffi does two things which are strange at least * uses CFLAGS when processing an assembly file * greps the output instead of checking the error code This makes it fail when trying to build with lto since clang will produce an warning about '-emit-llvm' not being used (since it is processing an assembly file). The above patch changes configure to use the error code. Dropping CFLAGS would also solve it.

Comment on attachment 520911 [details] [diff] [review] don't check for 'warning' This seems sensible enough, but I'd really rather have someone from upstream chime in. (Also, we do need to push all libffi changes upstream for sanity's sake.)

I have pinged the upstream thread: http://www.cygwin.com/ml/libffi-discuss/2011/msg00110.html
@Rafael: Maybe the topic of your mail to libffi-discuss was to cryptic so nobody knows what you envision to do with this patch. I know, the explanation is in your mail but some people don't have the time to read every mail with the necessary attentiveness. And then again I came across some developer who didn't know what llvm was. So I would say repost your mail with a more descriptive topic which lays out your intention clearly. Btw. I am not affiliated with the libffi-project, I just want to solve some communication problems.
The libffi list isn't always immediately responsive, either. You might have to ping the list a few times to get a response.
Trying yet again: http://www.cygwin.com/ml/libffi-discuss/2011/msg00116.html Do we have a strong policy of never having local patches to libffi? Once NSS merges to m-c this will be one of the two bugs (the other being 635790) blocking building m-c with clang.
We do have local patches to libffi, but we try to keep them minimal. Since you've pushed thrice to upstream, we can take it. :) Can you roll a new patch with your additions added to js/src/ctypes/libffi.patch, with the bug# referenced?
I am not sure how js/src/ctypes/libffi.patch was generated the first time. To try to reduce the noise (file order for example) in this change I did echo > js/src/ctypes/libffi.patch for i in js/src/ctypes/libffi/Makefile.in js/src/ctypes/libffi/configure js/src/ctypes/libffi/src/x86/ffi64.c js/src/ctypes/libffi/src/arm/ffi.c js/src/ctypes/libffi/src/arm/ffitarget.h js/src/ctypes/libffi/src/arm/sysv.S js/src/ctypes/libffi/testsuite/lib/libffi-dg.exp js/src/ctypes/libffi/testsuite/libffi.call/cls_double_va.c js/src/ctypes/libffi/testsuite/libffi.call/cls_longdouble_va.c js/src/ctypes/libffi/include/ffi.h.in js/src/ctypes/libffi/configure.ac; do git diff -U8 tmp tmp2 $i >> js/src/ctypes/libffi.patch; done

Sounds fine, as long as everything's still in there!
To the best of my knowledge it is.
