* config/alpha/alpha.c (alpha_rtx_costs): Handle HIGH.
(alpha_preferred_reload_class): Handle CONST_VECTOR.
(alpha_emit_set_const_1): Add no_output parameter; don't emit
rtl if true.
(alpha_emit_set_const): Likewise. Make static.
(alpha_emit_set_long_const): Make static.
(alpha_extract_integer): Split out from alpha_expand_mov.
(alpha_split_const_mov): Likewise.
(alpha_expand_mov): Use them. Handle CONST_VECTOR.
(alpha_legitimate_constant_p): New.
* config/alpha/alpha-protos.h: Update.
* config/alpha/alpha.h (REGISTER_MOVE_COST): Correct fp<->gp cost.
(LEGITIMATE_CONSTANT_P): Re-implement with a function.
* config/alpha/alpha.md (movsi): Add n alternative.
(movsi_nt_vms, movdi_er_nofix, movdi_er_fix, movdi_fix): Likewise.
(mov<VEC>_fix, mov<VEC>_nofix): Add i alternative.
(splitters for all of the above): Use alpha_split_const_mov.
* config/alpha/predicates.md (non_add_const_operand): New.
(non_zero_const_operand): New.
(input_operand): Use alpha_legitimate_constant_p after reload.
