--- Comment #9 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Jambor <[email protected]>: https://gcc.gnu.org/g:f7e335aa007f32a003dde88a7500e326b1dcef65 commit r16-7372-gf7e335aa007f32a003dde88a7500e326b1dcef65 Author: Martin Jambor <[email protected]> Date: Fri Feb 6 22:49:43 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.
