[PATCH] D122850: [AMDGPU] Fix regression with vectorization limiting

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUTargetTransformInfo.cpp:313
+  // interleaving loops, so we lie to avoid trying to use all registers.
+  return std::min(NumRegs, 4u);
 }
----------------
4 seems really small
