[PATCH] D132531: [AArch64] Reserve more physical registers

[Guozhi Wei via Phabricator via llvm-commits]

Carrot added a comment.

I want to reserve most of the physical registers, so only a small number of registers can be used by register allocator. Then I can write small test cases to simulate high register pressure situation, it will be much easier to test and debug register allocation changes.
