--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Stefan Schulze Frielinghaus <stefa...@gcc.gnu.org>: https://gcc.gnu.org/g:2c832ffedf06ff614fc36c44ab6c892d84075e08 commit r11-460-g2c832ffedf06ff614fc36c44ab6c892d84075e08 Author: Stefan Schulze Frielinghaus <stefa...@linux.ibm.com> Date: Tue May 5 19:44:19 2020 +0200 tree-optimization: Fix use of uninitialized variables warnings [PR94952] While bootstrapping GCC on S/390 with --enable-checking=release several warnings about use of uninitialized variables bitpos, bitregion_start, and bitregion_end of function pass_store_merging::process_store are raised. According to PR94952 these seem to be false positives which are silenced by initialising the mentioned variables. Bootstrapped on S/390. Ok for master and releases/gcc-10 assuming that regtest succeeds (still running but I don't see a reason why it should fail)? gcc/ChangeLog: 2020-05-18 Stefan Schulze Frielinghaus <stefa...@linux.ibm.com> PR tree-optimization/94952 * gimple-ssa-store-merging.c (pass_store_merging::process_store): Initialize variables bitpos, bitregion_start, and bitregion_end in order to silence warnings about use of uninitialized variables.
