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

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

It could be a call to some library function (from a user-provided library).  I agree that this is a very unlikely scenario, but we've had a customer report a bug related to a similar situation.

If you want to proceed with this, could you make it opt-in for targets that want it?
