Mark gc.relocate and gc.result as readnone (try 2)

Authored by reames on Mar 16 2021, 11:47 AM.



As noted in the LangRef, these are semantically readnone projections from the result value of the associated statepoint. However, it turned out we had a few latent bugs being covered up by the fact we were only marking them readonly (see PR49607 for context).

As of this change, all known issues are resolved. This is a deliberately minimal patch to make it easy to test downstream and revert with minimal change if that turns out to be necessary.

Depends on:

  • D98728 [LICM] Fix a crash when sinking instructions w/token operands

Hi Philip, at the moment my downstream testing did not show any problems.

So I guess we can try and land it. In case some troubles I'll revert this change back.
