--- Comment #10 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:1212cfad09378bc85860a7de22dde0cf7a19fd01 commit r11-2447-g1212cfad09378bc85860a7de22dde0cf7a19fd01 Author: Richard Biener <rguent...@suse.de> Date: Fri Jul 24 13:44:09 2020 +0200 Improve var-tracking dataflow iteration order This builds upon the rev_post_order_and_mark_dfs_back_seme improvements and makes vt_find_locations iterate over the dataflow problems for each toplevel SCC separately, improving memory locality and avoiding to process nodes after the SCC before the SCC itself stabilized. On the asan_interceptors.cc testcase this for example reduces the number of visited blocks from 3751 to 2867. For stage3-gcc this reduces the number of visited blocks by ~4%. 2020-07-28 Richard Biener <rguent...@suse.de> PR debug/78288 * var-tracking.c (vt_find_locations): Use rev_post_order_and_mark_dfs_back_seme and separately iterate over toplevel SCCs.
