* config/pa/constraints.md: Adjust unused letters. Change "T"
constraint to match_test floating_point_store_memory_operand().
* config/pa/predicates.md (reg_plus_base_memory_operand): New.
(base14_operand): New.
(floating_point_store_memory_operand): New.
(integer_store_memory_operand): Revise to use base14_operand and
reg_plus_base_memory_operand.
(move_dest_operand): Allow symbolic_memory_operands.
(symbolic_memory_operand): Check for LO_SOM.
(symbolic_operand): Change default case to break.
* config/pa/pa.md: Remove unamed DFmode and SFmode patterns to force
CONST_DOUBLE values to be reloaded by putting them into memory when
the destination is a floating point register.
(movdf): Remove code to handle CONST_DOUBLE.
(movsf): Likewise.
(reload_indf_r1): New.
(reload_insf_r1): New.
Consistently use "Q" and "T" constraints with integer and floating
point move instructions, respectively.
(movdi): Remove FAIL.
Change predicate for source operand unamed DImode move from
general_operand to move_src_operand.
(umulsidi3): Change predicate for destination operand to
register_operand.
Likewise for similar unamed patterns.
* config/pa/pa-protos.h (pa_legitimize_reload_address): Declare.
* config/pa/pa.c (pa_symbolic_expression_p): Remove extra parenthesis.
(hppa_legitimize_address): Simplify mask calculation.
(pa_emit_move_sequence): Revised handling of secondary reloads from
REG+D addresses for floating point loads and stores. Directly handle
loading CONST0_RTX (mode) to a floating point register.
(pa_secondary_reload): Handle reloading DF and SFmode constant values
to floating point registers. Don't restrict secondary reloads to
floating point registers to integer modes. Revise some comments and
cleanup some code.
(TARGET_LEGITIMATE_ADDRESS_P): Define.
(pa_legitimate_address_p): New.
(pa_legitimize_reload_address): New.
* config/pa/pa.h (STRICT_REG_OK_FOR_INDEX_P): New.
(STRICT_REG_OK_FOR_BASE_P): New.
(GO_IF_LEGITIMATE_ADDRESS): Delete. Update some related comments.
(LEGITIMIZE_RELOAD_ADDRESS): Revise to use pa_legitimize_reload_address.
