[PATCH] D68930: [InstCombine] Shift amount reassociation in shifty sign bit test (PR43595)

[Dávid Bolvanský via Phabricator via llvm-commits]

>> I don't think the intent was to disrespect whatever code this pattern showed up in, but to ask if there are any stats for common clang benchmarks. That's the only way we can draw a line on these kinds of decisions. Every pattern is presumably showing up somewhere real for someone, so we can't distinguish where it belongs just based on existence.

Strong +1.
