[PATCH] D117328: GlobalISel: Add bitcast to tryFoldUnmergeCast

[Petar Avramovic via Phabricator via llvm-commits]

Petar.Avramovic added a comment.

Bitcast can be created during legalizer. About post legalizer combiner, I don't think we run artifact combiner there, If we leave it it might block some combines combines that would become available after bitcast is combined.
