--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Jan Hubicka <hubi...@gcc.gnu.org>: https://gcc.gnu.org/g:c5397d343ff1365fcebcf3ebabe140608874aac3 commit r14-10487-gc5397d343ff1365fcebcf3ebabe140608874aac3 Author: Jan Hubicka <hubi...@ucw.cz> Date: Mon Jul 22 18:01:57 2024 +0200 Compare loop bounds in ipa-icf Hi, this testcase shows another poblem with missing comparators for metadata in ICF. With value ranges available to loop optimizations during early opts we can estimate number of iterations based on guarding condition that can be split away by the fnsplit pass. This patch disables ICF when number of iteraitons does not match. Bootstrapped/regtesed x86_64-linux, will commit it shortly gcc/ChangeLog: PR ipa/115277 * ipa-icf-gimple.cc (func_checker::compare_loops): compare loop bounds. gcc/testsuite/ChangeLog: * gcc.c-torture/compile/pr115277.c: New test. (cherry picked from commit 0d19fbc7b0760ce665fa6a88cd40cfa0311358d7)
