--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by David Malcolm <dmalc...@gcc.gnu.org>: https://gcc.gnu.org/g:bddd8d86e3036e480158ba9219ee3f290ba652ce commit r13-2007-gbddd8d86e3036e480158ba9219ee3f290ba652ce Author: David Malcolm <dmalc...@redhat.com> Date: Tue Aug 9 19:58:54 2022 -0400 analyzer: fix missing -Wanalyzer-use-of-uninitialized-value on special-cased functions [PR106573] We were missing checks for uninitialized params on calls to functions that the analyzer has hardcoded knowledge of - both for those that are handled just by state machines, and for those that are handled in region-model-impl-calls.cc (for those arguments for which the svalue wasn't accessed in handling the call). Fixed thusly. gcc/analyzer/ChangeLog: PR analyzer/106573 * region-model.cc (region_model::on_call_pre): Ensure that we call get_arg_svalue on all arguments. gcc/testsuite/ChangeLog: PR analyzer/106573 * gcc.dg/analyzer/error-uninit.c: New test. * gcc.dg/analyzer/fd-uninit-1.c: New test. * gcc.dg/analyzer/file-uninit-1.c: New test.
