[PATCH] D123693: Transform illegal intrinsics to V_ILLEGAL

[Leon Clark via Phabricator via llvm-commits]

Leonc added a comment.

Next steps:

- Get feedback from team.
- Add tests.
- Extend coverage to `INTRINSIC_WO_CHAIN` and `INTRINSIC_VOID`.

Issues:

- Not all intrinsics marked as custom are handled by the target lowering functions. This is the reason `INTRINSIC_WO_CHAIN` and `INTRINSIC_VOID` are not covered yet.
  - It might be possible to determine if an intrinsic //will// be expanded if it is allowed to fall through.
