[PATCH] D132717: [AArch64] Add an option to reserve physical registers from RA

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Do we actually need getReservedRegsForRA() to be something different from getReservedRegs()?  Having getReservedRegs() return bogus values won't actually hurt anything, I think.  The issue with the other patch was just that we don't want to expose feature flags that we know don't actually work.
