(register_known_analyzer_functions): Use make_kf_strlen. * kf.cc (class kf_strlen::impl_call_pre): Replace with implementation of kf_analyzer_get_strlen from kf-analyzer.cc. Handle "UNKNOWN" return from check_for_null_terminated_string_arg by falling back to a conjured svalue. (make_kf_strlen): New. (register_known_functions): Use make_kf_strlen. * known-function-manager.h (make_kf_strlen): New decl. gcc/testsuite/ChangeLog: PR analyzer/105899 * gcc.dg/analyzer/null-terminated-strings-1.c: Update expected results on symbolic values. * gcc.dg/analyzer/strlen-1.c: New test.
