[PATCH] D109240: GlobalISel: Artifact combine merge-like and unmerge into copy

[Petar Avramovic via Phabricator via llvm-commits]

Petar.Avramovic updated this revision to Diff 469617.
Petar.Avramovic retitled this revision from "GlobalISel: Artifact combine merge-like opcode and unmerge into copy" to "GlobalISel: Artifact combine merge-like and unmerge into copy".
Petar.Avramovic added a comment.

Use Value finder to search for unmerged elements. In some tests skips a few combine steps since value finder looks through artifacts.
