[PATCH] D103108: [CUDA][HIP] Promote const variables to constant

[Artem Belevich via Phabricator via cfe-commits]

tra added a comment.

Overall looks good, though I've got one more question.



================
Comment at: clang/test/SemaCUDA/device-use-host-var.cu:90
+  const int &ref_const_var = global_const_var;
   const int &ref_constexpr_var = global_constexpr_var;
   *out = ref_host_var;
----------------
What happens if we have  `const int &ref_foo = something_we_cant_emit_on_device;`?
Both if ref_foo is and isn't used from device code.
