This is odd. This atomic is implemented in CGAtomic.cpp, but it's being
lowered as a library call because "UseLibcall" is true:
bool UseLibcall = (Size != Align ||
getContext().toBits(sizeChars) > MaxInlineWidthInBits);
I don't think it should in your case. That looks like a bug, but I'm not an
atomic library expert. Can you create a bug in bugzilla (
Possibly, you should send an email with this error and the bugzilla ID to
the list, just to make sure you get the attention of the right people.
