[libcxx-commits] [PATCH] D134625: Summary:bug fix! Rotation direction on `__countl_zero()`probably unnoticed because only affects rare cases(does not affect 128 bit ints because rotation is effectively swap)(does not affect integers of sizes less or equal to 64bits)

[Joe Loser via Phabricator via libcxx-commits]

jloser added a comment.

Is there a test we can add to exhibit this bug and verify this fixes the problem?
