[PATCH] D26585: [AMDGPU] Add wave barrier builtin

[Tom Stellard via llvm-commits]

tstellarAMD added inline comments.


================
Comment at: lib/Target/AMDGPU/SIInstrInfo.cpp:903-906
+  case AMDGPU::WAVE_BARRIER: {
+    MI.eraseFromParent();
+    break;
+  }
----------------
Does it matter that Post-RA scheduler runs after the Post-RA Pseudo Expansion pass?
