Hi!This function accesses arguments of builtin call without checking the right arguments are actually provided. Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? The is_gimple_call in there is meant as a performance thing, we could call gimple_call_builtin_p first and then only check gimple_call_with_bounds_p, but that would unnecessarily test compatibility of arguments even for calls without bounds. 2017-02-21 Jakub Jelinek <ja...@redhat.com> PR target/79633 * tree-chkp-opt.c (chkp_optimize_string_function_calls): Use is_gimple_call instead of comparing gimple_code with GIMPLE_CALL. Use gimple_call_builtin_p. * gcc.target/i386/mpx/pr79633.c: New test.
OK. jeff
