[PATCH] D50725: [SystemZ] Replace subreg_r with subreg_h

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

This is just a demonstration of what I meant in the comments for llvm.org/PR38544: getting rid of explicit overlapping subregister indices solves the problem encountered in `tc_subregliveness_noliveseg.ll`.
