gnu/llvm/llvm/lib/CodeGen: PrologEpilogInserter.cpp
Log message:
The clang feature -fzero-call-used-regs attempts to zero out some
registers before returning, but is not aware of the register used for
retguard, so it breaks if the two features are used together.
Make zero-call-used-regs aware of the retguard register.
Fixes a crash reported in qemu where this zero-call-used-regs feature is
used. Fix tested by brad.
