[LLVMdev] PR19267 - Add a feature to clobber non-calle-save regs in the prolog.

[Andrew Trick]

This is a feature I’m considering for the LLVM backend. Feel free to provide input in the following PR.

llvm.org/pr19267 - Add a feature to clobber non-callee-save regs in the prolog.

I’m copying llvm-dev because it seems like something that others must have already done or at least thought about at some point.
