[PATCH] D90505: [AMDGPU] Improve FLAT scratch detection

[Jay Foad via Phabricator via llvm-commits]

foad added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstrInfo.h:580
+    return isSegmentSpecificFLAT(MI) &&
+           AMDGPU::getFlatScratchInst(MI.getOpcode()) >= 0;
   }
----------------
If getFlatScratchInst is just a table lookup, is there any need to do the isSegmentSpecificFLAT test first?
