Rationalization removes all GT_NOP nodes, and we do not seem to introduce any of these before LSRA (and especially not the typed "passthrough" GT_NOP nodes). This code is just wrong for the passthrough nodes, so just switch all the LSRA code to only handle potential void NOPs. Fix dotnet#93048

cc @dotnet/jit-contrib PTAL @kunalspathak No diffs. Some TP improvements on linux-x64, not sure what's up with that -- I guess Clang changed codegen strategy in some way. |
