[PATCH] D136015: [InstCombine] Fold series of instructions into mull

[Allen zhong via Phabricator via llvm-commits]

Allen added a comment.

> If you remove that line, notice that the values in the later multiply get commuted. That happens before we reach this transform, so the test is trying to ensure that the exact placement of the values at runtime is the same as specified in the test.

Thanks very much for your guidance.
