[LLVMdev] Is r174746 broken on ARM?

[Dmitry Antipov]

Hello Hal,

I have a strong suspicion that your constant folding optimization
introduced at r174746 is broken on ARM. There is a bug about it:

http://llvm.org/bugs/show_bug.cgi?id=15581

There is no such issue with 3.2, and reverting r174746 on top of
r178740 also fixes the problem. I'm trying to fix it myself, but
still have no good ideas; so it would be great to have an advice
from you.

Thanks in advance,
Dmitry
