Makefile.in (rtlanal.o): Depend on hard-reg-set.h.
* Makefile.in (rtlanal.o): Depend on hard-reg-set.h.
($HOST_PREFIX_1)rtlanal.o: Remove rules for building
(mostlyclean): Corresponding changes.
* rtlanal.c (hard-reg-set.h): Include.
(rtx_unstable_p): Do not treat the argument pointer specially
if it is not a fixed register.
(rtx_varies_p, rtx_addr_can_trap_p): Similarly.
