--- Comment #12 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jakub Jelinek <[email protected]>: https://gcc.gnu.org/g:21d09955d2b7755db7d5ba3cd4a314930b470da7 commit r11-10682-g21d09955d2b7755db7d5ba3cd4a314930b470da7 Author: Jakub Jelinek <[email protected]> Date: Wed Nov 23 19:09:31 2022 +0100 c: Fix compile time hog in c_genericize [PR107127] The complex multiplications result in deeply nested set of many SAVE_EXPRs, which takes even on fast machines over 5 minutes to walk. This patch fixes that by using walk_tree_without_duplicates where it is instant. 2022-11-23 Andrew Pinski <[email protected]> Jakub Jelinek <[email protected]> PR c/107127 * c-gimplify.c (c_genericize): Use walk_tree_without_duplicates instead of walk_tree for c_genericize_control_r. * gcc.dg/pr107127.c: New test. (cherry picked from commit 8a0fce6a51915c29584427fd376b40073c328090)
