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

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

The conflict between user-defined and inferred compositions causes a warning in the SystemZ build:

  warning: SubRegIndex SystemZ::subreg_h64 and SystemZ::subreg_h32 compose ambiguously as SystemZ::subreg_hh32 or SystemZ::subreg_h32

This patch eliminates the warning in cases where such a conflict is legitimate (by resolving it in favor of user-defined compositions).
