[PATCH] D115283: [AMDGPU] Set "amdgpu_hostcall" module flag if an AMDGPU function has calls to device lib functions that use hostcalls.

[Jon Chesterfield via Phabricator via cfe-commits]

JonChesterfield added a comment.

The asm variable used by rocm aomp is zero overhead, needs no compiler support and works exactly as one would wish under inlining or code elimination. The main argument against that approach seems to be it's an abi break, much like this patch was, and that it is per-code-object instead of per-function, which I still think is a benefit.
