pa.c (hppa_legitimize_address): Handle full offsets for PA2.0 FP loads and stores.
* pa.c (hppa_legitimize_address): Handle full offsets for PA2.0
FP loads and stores.
(following_call): Always return zero for the PA8000.
* pa.h (GO_IF_LEGITIMATE_ADDRESS): Handle full offsets for PA2.0
FP loads and stores.
(LEGITIMIZE_RELOAD_ADDRESS): Similarly.
