[PATCH] D40250: [OpenMP] Consistently use cubin extension for nvlink

[Jonas Hahnfeld via Phabricator via cfe-commits]

Hahnfeld added a comment.

A different approach would be to completely replace the type in `Driver::ConstructPhaseAction` but

1. this was previously considered a too radical change,
2. we currently don't have the necessary information (ToolChain, OffloadKind) to take that decision,
3. this might break in subtle places that compare the type with `TY_Object`.
