[PATCH] D139730: [OpenMP][DeviceRTL][AMDGPU] Support code object version 5

[Matt Arsenault via Phabricator via cfe-commits]

arsenm added inline comments.


================
Comment at: clang/lib/CodeGen/CGBuiltin.cpp:17146
+    Value *ABIVersion;
+    if (ABIVersionC) {
+      ABIVersion = CGF.Builder.CreateAlignedLoad(CGF.Int32Ty, ABIVersionC,
----------------
this must always pass


================
Comment at: openmp/libomptarget/plugins-nextgen/amdgpu/src/rtl.cpp:3037
+  if (getImplicitArgsSize() < utils::COV5_SIZE) {
+    DP("Setting fields of ImplicitArgs for COV4\n");
+  } else {
----------------
This isn't doing anything?


================
Comment at: openmp/libomptarget/plugins-nextgen/amdgpu/utils/UtilitiesRTL.h:36
 
-// The implicit arguments of AMDGPU kernels.
-struct AMDGPUImplicitArgsTy {
-  uint64_t OffsetX;
-  uint64_t OffsetY;
-  uint64_t OffsetZ;
-  uint64_t HostcallPtr;
-  uint64_t Unused0;
-  uint64_t Unused1;
-  uint64_t Unused2;
+enum IMPLICITARGS : uint32_t {
+  COV4_SIZE = 56,
----------------
This is getting duplicated a few places, should it move to a support header?

I don't love the existing APIs for this, I think a struct definition makes more sense
