[PATCH] D62653: [Mips][DSP] Fix physregs incorrectly marked as dead.

[Mirko Brkusanin via Phabricator via llvm-commits]

mbrkusanin added a comment.

Problem with handling everything in post-isel hooks is that it is after marking registers as dead. So we would need to mark every instruction that uses any part of DSPControl as having an post-isel hook and there are more than 100 instructions (including MicroMips variants).
