[PATCH] D153761: [AMDGPU] ISel for @llvm.amdgcn.cs.chain intrinsic (WIP)

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/IRTranslator.cpp:2517
+  if (!F || !F->isIntrinsic() || ID == Intrinsic::not_intrinsic ||
+      ID == Intrinsic::amdgcn_cs_chain)
     return translateCallBase(CI, MIRBuilder);
----------------
Probably should avoid touching the generic IRTranslator. Can you just handle this as a legalize on the intrinsic itself? Fundamentally this isn't really any different from emitting a libcall, you'd just need to access the CallLowering from the legalize function
