* config/mips/mips-protos.h (mips_subword, mips_output_move): Declare.
(mips_move_1word, mips_move_2words): Remove declaration.
(mips_split_64bit_move_p, mips_split_64bit_move): Declare.
(mips_restore_gp): Remove insn argument.
* config/mips/mips.h (FP_REG_RTX_P): New macro.
* config/mips/mips.c (volatile_buffer): Remove.
(mips_subword, mips_split_64bit_move_p, mips_split_64bit_move): New.
(mips_move_1word, mips_move_2words): Remove, replacing with...
(mips_output_move): ...this new function.
(mips_restore_gp): Remove insn argument. Adjust for above changes.
(print_operand): Make '%h' print %hi(op) for HIGH operands. Remove
handling of floating-point constants. Handle zero CONST_DOUBLE
arguments.
(mips_annotate_frame_insn): Replace with...
(mips_set_frame_expr): ...this, which just takes one argument.
(mips_frame_set): Change the register argument to an rtx.
(mips_emit_frame_related_store): Use mips_split_64bit_move_p to
check whether moves should be split. Use mips_split_64bit_move
to split them. Use mips_subword to generate the high and low
parts of a paired FPR. Adjust calls to frame_set and
mips_set_frame_expr.
(mips_expand_prologue): Simplify due to above changes.
* config/mips/mips.md: Add splitters for 64-bit moves on 32-bit
targets, replacing xisting register-only versions.
(UNSPEC_STORE_DF_HIGH): New unspec.
(UNSPEC_LOAD_DF_LOW, UNSPEC_LOAD_DF_HIGH): New unspecs.
(mulsi3_r4000, muldi3_internal2): Avoid use of mips_move_1word.
(*paradoxical_extendhidi2): Remove.
(movdi_internal, movdi_internal2): Use mips_output_move.
(*movdi_internal2_mips16, movsi_internal, movcc): Likewise.
(movsf_internal1, movsf_internal2): Likewise.
(movdf_internal1a): Likewise. Fix length and type of f <- G case.
(movdf_internal1b): Use mips_output_move. Fix type of f <- G case.
(movdf_internal2): Use mips_output_move. Fix lengths of FPR moves.
Add m <- G alternative.
(load_df_low, load_df_high, store_df_low): New patterns.
(movhi_internal): Use @ template instead of calling a function.
Remove unnecessary 'z' alternatives.
(movqi_internal): Likewise.
(exception_receiver): Update call to mips_restore_gp.
