--- Comment #10 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-15 branch has been updated by Martin Jambor <[email protected]>: https://gcc.gnu.org/g:f91405783afbb091f05b2cfa5f290a7c9b3b8853 commit r15-10832-gf91405783afbb091f05b2cfa5f290a7c9b3b8853 Author: Martin Jambor <[email protected]> Date: Mon Feb 16 19:06:51 2026 +0100 ipa-cp: Fix assert triggering with -fno-toplevel-reorder (PR 106260) with -fno-toplevel-reorder (and -fwhole-program), there apparently can be local functions without any callers. This is something that IPA-CP does not like because its propagation verifier checks that local functions do not end up with TOP in their lattices. Therefore there is an assert checking that all call-less unreachable functions have been removed, which tigers in PR 106260 with these two options. This patch detects the situation and marks the lattices as variable, thus avoiding both the assert trigger and the verification failure. gcc/ChangeLog: 2022-07-13 Martin Jambor <[email protected]> PR ipa/106260 * ipa-cp.cc (initialize_node_lattices): Replace assert that there are callers with handling that situation when -fno-toplevel_reorder. gcc/testsuite/ChangeLog: 2022-07-13 Martin Jambor <[email protected]> PR ipa/106260 * g++.dg/ipa/pr106260.C: New test.
