[PATCH] D140638: [Codegen][LegalizeIntegerTypes] New legalization strategy for scalar shifts: shift through stack

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri updated this revision to Diff 485202.
lebedev.ri added a comment.

Actually, code changes don't need full context, and that significantly reduces patch size,
allowing for full context in test changes. Should have thought of that first.
