[LLVMdev] [PATCH] 3.3 Release fix on ARM - atomics
...is set, which it is by default on armv7a, I presume.
>From that part of the code, I can infer that by the time
"MaxAtomicPromoteWidth = 64;", the variable SoftFloat is not properly set,
so a simple "if (!SoftFloat)" won't cut in there. It seems SoftFloat is
being set on HandleTargetFeatures() which is a virtual method, probably
called indirectly. Do you have a better place to set MaxAtomicInlineWidth =
64?
cheers,

[LLVMdev] [PATCH] 3.3 Release fix on ARM - atomics
Identified a while before the release, there is an issue with 64-bit
atomics on ARM that was making Clang mis-compile a lot of code, including
Clang itself.

Attached is a patch proposed by Benjamin with the corrections to the test.
I'm not an expert on how Clang lowers C11 atomics, but the resulting IR
seems correct, and after self-hosting Clang

I have asked on #gcc what gcc does. I have posted a detailed
description in the bug, but the summary is that there is some
cooperation with the kernel going on that shoul...
