--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-15 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:e1828db8e75a56eebf8ede53e1ae4fcbd0f3376f commit r15-10004-ge1828db8e75a56eebf8ede53e1ae4fcbd0f3376f Author: Richard Biener <rguent...@suse.de> Date: Fri Jul 18 09:02:09 2025 +0200 tree-optimization/120924 - up --param uninit-max-chain-len The PR shows that the uninit analysis limits are set too low in cases we lower switches to ifs as happens on s390x for a linux kernel TU. This causes false positive uninit diagnostics as we abort the attempt to prove that a value is initialized on all paths. The new testcase only would require upping to 9. PR tree-optimization/120924 * params.opt (uninit-max-chain-len): Up from 8 to 12. * gcc.dg/uninit-pr120924.c: New testcase. (cherry picked from commit cf9a479e3f909d5217e954788eb3c5b569e4bc52)
