[libcxx-commits] [PATCH] D129859: [libc++][ranges] Implement `ranges::{prev, next}_permutation`

[Konstantin Varlamov via Phabricator via libcxx-commits]

var-const updated this revision to Diff 448901.
var-const added a comment.

Reduce the input size used for the exhaustive permutation checks to avoid
hitting `constexpr` step limit in Clang; remove the Clang command-line option
because it's unrecognized by GCC.
