[PATCH] D42898: Do not spill CSR to stack on entry to noreturn functions

[pmb via Phabricator via llvm-commits]

myeisha added a comment.

I would rather make it generic, not break debug, and habe the user decide whether or not to apply this. If libraries are the concern it probably can't be the target's decision either. Would enabling the transform only with fp-elim and a cl option be just as good?
