[PATCH] D98814: [CUDA][HIP] Mark device var used by host only

[Artem Belevich via Phabricator via cfe-commits]

tra added inline comments.


================
Comment at: clang/lib/CodeGen/CGCUDANV.cpp:1102
+          Info.D->isUsed() && !Info.D->hasAttr<UsedAttr>()) {
+        CGM.addCompilerUsedGlobal(Info.Var);
+      }
----------------
Do we want to limit it further to only externally-visible variables?
I think we already externalize the variables we want to be visible across host/device boundary.
If the variable is not visible, there's no point keeping it around as the runtime will not be able to find it in the GPU binary.
