patch 9.0.1842: Need more accurate profiling Commit: https://github.com/vim/vim/commit/21d3212361f687704acb52cad7c1b9228e7c83f0 Author: Ernie Rael <errael@raelity.com> Date: Sat Sep 2 15:09:18 2023 +0200 patch 9.0.1842: Need more accurate profiling Problem: Need more accurate profiling Solution: Improve profiling results closes: #12192 Reduce overhead of checking if a function should be profiled, by caching results of checking (which are done with regexp). Cache uf_hash for uf_name in ufunc_T. Cache cleared when regexps are changed. Break at first match for has_profiling lookup.
