[PATCH] D47359: AMDGPU: Split AMDGPUTTI into GCNTTI and R600TTI

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: lib/Target/AMDGPU/AMDGPUTargetMachine.cpp:572-575
+  if (getTargetTriple().getArch() == Triple::r600)
+    return TargetTransformInfo(R600TTIImpl(this, F));
+  else
+    return TargetTransformInfo(GCNTTIImpl(this, F));
----------------
Why not implement separately for GCNTargetMachine and R600TargetMachine?
