[LLVMdev] Interaction of stacksave/restore and stack spills
Hi everyone,
I'm curious about the constraints that come with the usage of
llvm.stacksave/llvm.stackrestore. Specifically I was wondering what the
contract of their usage was with respect to SSA variables defined after
llvm.stacksave. It seems to me that they could get spilled to a stack slot,
which I'm concerned stackrestore might mess up. Is this a valid concern?
Thanks,
Keno
