In gsub is used with a string replacement or a map that doesn't have a default proc, we know for sure no code can cause the MatchData to escape the `gsub` call. In such case, we still have to allocate a new MatchData because we don't know what is the lifetime of the backref, but for any subsequent match we can re-use the MatchData we allocated ourselves, reducing allocations significantly. This partially fixes [Misc #20652], except when a block is used, and partially reduce the performance impact of abc0304cb28cb9dcc3476993bc487884c139fd11 / [Bug #17507] ``` compare-ruby: ruby 3.5.0dev (2025-02-24T09:44:57Z master 5cf146399f) +PRISM [arm64-darwin24] built-ruby: ruby 3.5.0dev (2025-02-24T10:58:27Z gsub-elude-match da966636e9) +PRISM [arm64-darwin24] warming up.... | |compare-ruby|built-ruby| |:----------------|-----------:|---------:| |escape | 3.577k| 3.697k| | | -| 1.03x| |escape_bin | 5.869k| 6.743k| | | -| 1.15x| |escape_utf8 | 3.448k| 3.738k| | | -| 1.08x| |escape_utf8_bin | 6.361k| 7.267k| | | -| 1.14x| ``` Co-Authored-By: Étienne Barrié <etienne.barrie@gmail.com>
