<Nag mode>This patch is identical in concept to this one 

2000-10-24  Richard Henderson  <rth@cygnus.com>

	* rtlanal.c (rtx_unstable_p, rtx_varies_p): Don't consider pic
	register stable if PIC_OFFSET_TABLE_REG_CALL_CLOBBERED.

Can someone please take a look at the patch?

If it helps, I'm quite willing to negate the logic, and turn
ARG_POINTER_INVARIANT into ARG_POINTER_REG_CALL_CLOBBERED.  I hadn't seen
Richard's patch when I made mine.
