[PATCH] D130729: [InferAddressSpaces] [AMDGPU] Add inference for flat_atomic intrinsics

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/test/CodeGen/AMDGPU/gep-const-offset-address-space.ll:158
+; CHECK-NEXT:    v_pk_mov_b32 v[0:1], s[6:7], s[6:7] op_sel:[0,1]
+; CHECK-NEXT:    global_atomic_add_f64 v2, v[0:1], s[0:1]
+; CHECK-NEXT:    s_endpgm
----------------
I wouldn't expect this transform to happen. I would expect to emit the flat instruction for the flat atomic despite the address space
