[PATCH] D50977: [TableGen] Prefer user-defined subregister compositions over inferred ones

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

I've looked into this and there is no way to distinguish the case of hh (no warning) and ll (emit a warning).  They are both equivalent: a user-defined composition vs. pre-existing subreg.

I don't think we can easily handle this right now, and I don't really want to be implementing a whole new functionality in TableGen for this (although I'm not opposed to the concept).
