        PR c/89946
        * varasm.c (assemble_start_function): Don't use tree_fits_uhwi_p
        and gcc_unreachable if it fails, just call tree_to_uhwi which
        verifies that too.  Test TREE_CHAIN instead of list_length > 1.
        Start warning message with a lower-case letter.  Formatting fixes.
c-family/
        * c-attribs.c (handle_patchable_function_entry_attribute): Add
        function comment.  Warn if arguments of the attribute are not positive
        integer constants.
testsuite/
        * c-c++-common/pr89946.c: New test.
