[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: lib/Target/AMDGPU/SIISelLowering.cpp:1643
                                       SIMachineFunctionInfo &Info) {
-  if (Info.hasWorkItemIDX())
-    Info.setWorkItemIDX(allocateVGPR32Input(CCInfo));
+  const unsigned Mask = 0x3ff;
+  ArgDescriptor Arg;
----------------
This should be derived from the subtarget maximum workgroup size
