--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:512429a885e87bef51057a001681b7d8d106e807 commit r11-7949-g512429a885e87bef51057a001681b7d8d106e807 Author: Richard Biener <rguent...@suse.de> Date: Thu Apr 1 11:51:33 2021 +0200 tree-optimization/99863 - clear vector CTOR TREE_SIDE_EFFECTS When we gimplify a vector CTOR the original CONSTRUCTOR tree remains but we fail to recompute flags such as TREE_SIDE_EFFECTS. This causes later GENERIC folding of them in vector lowering to give up since the match.pd machinery is careful about TREE_SIDE_EFFECTS. Fixing this makes vector lowering produce much less garbage and thus following the IL for PR99793 easier. 2021-04-01 Richard Biener <rguent...@suse.de> PR tree-optimization/99863 * gimplify.c (gimplify_init_constructor): Recompute vector constructor flags.
