Hi,
It seems that quite some callers of refers_to_regno_p are interested in
testing a single register number only. The caller code can be
simplified by adding an overload for refers_to_regno_p. This is what
the patch does. No functional changes. Tested with 'make all-gcc' on
sh-elf cross config and bootstrapped on i686-pc-linux-gnu.
OK for trunk?
Cheers,
Oleg

OK for the trunk. Though I think further patches of this nature should
probably wait until stage1 reopens.
