[PATCH] D150671: RISCV/InstrInfo: model register pressure for MICombiner

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfo.cpp:1418
+
+  unsigned GPRLimit = TRI->getRegPressureSetLimit(
+      *MBB->getParent(), RISCV::RegisterPressureSets::GPR);
----------------
Should this be using RegisterClassInfo::getRegPressureSetLimit which will take into account Reserved registers? I see uses of that in `RegPressureTracker`
