llvm combines "ADD frameindex, constant" to OR
Hi all,
I've been working on a backend of our architecture and noticed llvm performs
following combining although one of operands is FrameIndex.
Combining: t114: i64 = add FrameIndex:i64<0>, Constant:i64<56>
Creating new node: t121: i64 = or FrameIndex:i64<0>, Constant:i64<56>
... into: t121: i64 = or FrameIndex:i64<0>, Constant:i64<56>
