[PATCH] D105192: [AMDGPU] Optimize VGPR LiveRange in waterfall loops

[Jay Foad via Phabricator via llvm-commits]

foad added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIOptimizeVGPRLiveRange.cpp:501
+    // so we have to increment the iterator before setReg() to avoid skipping
+    // some uses.
+    ++I;
----------------
Can you use something like `for (auto &I : make_early_inc_range(MRI->use_operands(Reg)))`?
