[PATCH] D110337: [AMDGPU] Use "amdgpu-hostcalls" attribute to detect if a kernel function hostcall for GPU printf.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

I do not want to add any more attributes to indicate a feature is used. If anything, we would use an attribute to indicate that there is no host call. I'm not sure an attribute is the right solution here. I think we should just rely on a known externally visible global symbol name
