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

[Guozhi Wei via Phabricator via llvm-commits]

Carrot added a comment.

It's not necessary strictly speaking. The only problem of getReservedRegs is it is used by isAnyArgRegReserved. Testing this new kind of reserved register in isAnyArgRegReserved doesn't make sense. A possible solution is moving current content of getReservedRegs to a new function getStrictlyReservedRegs, and call this function from getReservedRegs and isAnyArgRegReserved. I will try it.
