Extended Description

crtfastmath.c is miscompiled at least on x86/linux. See #2006 for details.

[asl]

This is 4.2-specific stuff. We should handle "force_align_arg_pointer" function attribute.

[lattner]

This is a bug, but doesn't block 1634.

Any update on this?

[asl]

I have partly-working patch and hope to continue it soon.

[asl]

Actually, we can easily ignore this attribute. New stack realignment code handles this case (attribute was introduced to workaround poor gcc's stack realignment support) without any problems.
