[PATCH] D142393: [OpenMP] Add 'amdgpu-flat-work-group-size' to OpenMP kernels

[Matt Arsenault via Phabricator via cfe-commits]

arsenm added inline comments.


================
Comment at: clang/lib/CodeGen/TargetInfo.cpp:9552
     F->addFnAttr("uniform-work-group-size", "true");
+  if (IsOpenMPkernel)
+    F->addFnAttr("amdgpu-flat-work-group-size",
----------------
Probably shouldn’t check the language, just it’s a kernel. Also shouldn’t emit this if it’s the default 1024. I’ve been trying to cut down on the superfluous attribute spam
