* config/mips/mips-protos.h (mips_split_type): New enum.
(mips_split_64bit_move_p, mips_split_doubleword_move): Delete.
(mips_split_move_p, mips_split_move, mips_split_move_insn_p)
(mips_split_move_insn): Declare.
* config/mips/mips.c (mips_tuning_info): New variable.
(mips_load_store_insns): Use mips_split_move_insn_p instead of
mips_split_64bit_move_p.
(mips_emit_move_or_split, mips_mult_move_p): New functions.
(mips_split_64bit_move_p): Rename to...
(mips_split_move_p): ...this and take a mips_split_type argument.
Generalize to all moves. Call mips_mult_move_p.
(mips_split_doubleword_move): Rename to...
(mips_split_move): ...this and take a mips_split_type argument.
Assert that mips_split_move_p holds.
(mips_insn_split_type, mips_split_move_insn_p, mips_split_move_insn):
New functions.
(mips_output_move): Use mips_split_move_p instead of
mips_split_64bit_move_p. Handle MULT $0, $0 moves.
(mips_save_reg): Use mips_emit_move_or_split.
(mips_sim_reset): Assign to curr_state. Call targetm.sched.init
and advance_state.
(mips_sim_init): Call targetm.sched.init_dfa_pre_cycle_insn and
targetm.sched.init_dfa_post_cycle_insn, if defined.
(mips_sim_next_cycle): Assign to curr_state. Use advance_state
instead of state_transition.
(mips_sim_issue_insn): Assign to curr_state. Use
targetm.sched.variable_issue to see how many more insns
can be issued.
(mips_seq_time, mips_mult_zero_zero_cost)
(mips_set_fast_mult_zero_zero_p, mips_set_tuning_info)
(mips_expand_to_rtl_hook): New functions.
(TARGET_EXPAND_TO_RTL_HOOK): Define.
* config/mips/mips.md (move_type): Add imul.
(type): Map imul move_types to imul.
(*movdi_32bit, *movti): Add imul alternatives.
Use mips_split_move_insn_p and mips_split_move_insn instead of
mips_split_64bit_move_p and mips_split_doubleword_move in move
splitters.

* gcc.target/mips/madd-9.c: Force code to be tuned for the 4kc
and test that the accumulator is initialized using MULT.
* gcc.target/mips/mips32-dsp-accinit-1.c: New test.
* gcc.target/mips/mips32-dsp-accinit-2.c: Likewise.
