Options

pa-protos.h (compute_frame_size): Use HOST_WIDE_INT for frame sizes. 

	* pa-protos.h (compute_frame_size): Use HOST_WIDE_INT for frame sizes.
	* pa.c (store_reg, store_reg_modify, load_reg, set_reg_plus_d):
	Likewise.  Handle frames larger than 0x7fffffff on 64-bit ports.
	(emit_move_sequence): Check scratch_reg first in various if statements.
	Extend source simplification to handle all 64-bit CONST_INTs.
	(pa_output_function_prologue): Use HOST_WIDE_INT_PRINT_DEC for printing
	frame size.
	(hppa_expand_prologue, hppa_expand_epilogue): Use HOST_WIDE_INT for
	frame offset calculations.
	* pa.h (NEW_HP_ASSEMBLER): Add comment.
	(MAX_LEGIT_64BIT_CONST_INT, MIN_LEGIT_64BIT_CONST_INT,
	LEGITIMATE_64BIT_CONST_INT_P): Define.
	(LEGITIMATE_CONSTANT_P): Use LEGITIMATE_64BIT_CONST_INT_P.  Treat
	any CONST_INT as legitimate during and after reload.
	(VAL_32_BITS_P, INT_32_BITS): Define.
	(LEGITIMIZE_RELOAD_ADDRESS): Handle large frame offsets.

In 64-bit mode, we reject CONST_DOUBLES. We also reject CONST_INTS
that need more than three instructions to load prior to reload. This
limit is somewhat arbitrary. It takes three instructions to load a
CONST_INT from memory but two are memory accesses. It may be better
to increase the allowed range for CONST_INTS. We may also be able
to handle CONST_DOUBLES. */
