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-attribs.c (handle_patchable_function_entry_attribute): Add
function comment.  Warn if arguments of the attribute are not positive
integer constants.

* c-c++-common/pr89946.c: New test.
