--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <[email protected]>: https://gcc.gnu.org/g:e5bcb08d132bf753178a2b30962b4a9d3452c4f2 commit r16-7000-ge5bcb08d132bf753178a2b30962b4a9d3452c4f2 Author: Andrew Pinski <[email protected]> Date: Wed Jan 14 16:44:17 2026 -0800 slsr: Fix some undefined/overflow introducing bugs in SLSR [PR106883] This fixes the first part of SLSR incorrectly inserting undefined code (overflow) into the IR. The easiest way is to rewrite the statement after creating it using rewrite_to_defined_unconditional. This fixes the testcases from PR 121347 (and a few others) which all cause an infinite loops to appear. I will be posting the fix for replace_rhs_if_not_dup later and at that point I will add a few testcases. Bootstrapped and tested on x86_64-linux-gnu with no regressions.
