[PATCH] D121491: [AMDGPU] Restrict machine copy propagation from creating unaligned classes

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstrInfo.cpp:4748
                                           bool IsAllocatable) {
   if ((IsAllocatable || !ST.hasGFX90AInsts() || !MRI.reservedRegsFrozen()) &&
       (((TID.mayLoad() || TID.mayStore()) &&
----------------
This reservedRegsFrozen check is probably obsolete
