[LLVMdev] __atomic_fetch_add on ARM
I think this is two bugs in one:
* In ABIs that don't use external functions for atomics (linux hard
float at least), we incorrectly decide to use function calls.
* In ABIs that do use external function calls (non hard float linux?),
we don't have code to actually generate the calls.
See the thread in
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130415/078021.html.

[LLVMdev] __atomic_fetch_add on ARM
Hi Benjamin,
Several people (including me) are hitting this bug on ARM:
http://llvm.org/bugs/show_bug.cgi?id=15429
>From my investigations it happens on Ubuntu 12.10+ but not on 12.04. From
Tom Gail's, it happens with --enable-optimized and doesn't without. You
seem to have a clue on what that happens, can you shed some light on the
matter?
I see this error when self-hosting Clang

If I build with gcc, there are no problems.
The 3.0-4 distribution of clang says that it was updated for gcc 4.7.2.
