`RegisterClassInfo::getRegPressureSetLimit` is a wrapper of `TargetRegisterInfo::getRegPressureSetLimit` with some logics to adjust the limit by removing reserved registers. It seems that we shouldn't use `TargetRegisterInfo::getRegPressureSetLimit` directly, just like the comment "This limit must be adjusted dynamically for reserved registers" said. Separate from llvm#118787

I've reverted this in eeac0ff, because it causes a very large compile-time regression, see https://llvm-compile-time-tracker.com/compare.php?from=e3e26dc41a6ad78c35a1a723cd77f5db8599797d&to=b4e17d4a314ed87ff6b40b4b05397d4b25b6636a&stat=instructions:u. If you need a test case for analysis, a good one is probably k.cc from kimwitu++, which regresses by more than 6%. |
