* config/i386/i386.h (enum ix86_fpcmp_strategy): New.
* config/i386/i386.md (cbranchxf4, cstorexf4, cbranch<MODEF>4,
cstore<MODEF>4, mov<X87MODEF>cc): Change predicate to
ix86_fp_comparison_operator.
(*fp_jcc_1_mixed, *fp_jcc_1_sse, *fp_jcc_1_387, *fp_jcc_2_mixed,
*fp_jcc_2_sse, *fp_jcc_2_387): Delete
(*fp_jcc_3_387, *fp_jcc_4_387, *fp_jcc_5_387, *fp_jcc_6_387,
*fp_jcc_7_387, *fp_jcc_8<MODEF>_387): Eliminate call to
!ix86_use_fcomi_compare, change ix86_fp_jump_nontrivial_p call
to !TARGET_CMOVE, change predicate to ix86_fp_comparison_operator.
(related splits): Change predicate to ix86_fp_comparison_operator.
* config/i386/predicates.md: Use ix86_trivial_fp_comparison_operator
instead of ix86_fp_comparison_codes.
(ix86_trivial_fp_comparison_operator,
ix86_fp_comparison_operator): New.
* config/i386/i386-protos.h (ix86_fp_comparison_strategy): New.
(ix86_expand_compare): Eliminate last two parameters.
(ix86_fp_jump_nontrivial_p): Kill.
* config/i386/i386.c (put_condition_code): Eliminate call to
ix86_fp_comparison_codes and subsequent assertion.
(ix86_fp_comparison_codes): Eliminate.
(ix86_fp_swap_condition): New.
(ix86_fp_comparison_arithmetics_cost, ix86_fp_comparison_fcomi_cost,
ix86_fp_comparison_sahf_cost, ix86_use_fcomi_compare): Consolidate
into ix86_fp_comparison_cost and ix86_fp_comparison_strategy.
(ix86_prepare_fp_compare_args): Use ix86_fp_comparison_strategy
and ix86_fp_swap_condition.
(ix86_expand_fp_compare): Eliminate code for second jump/bypass jump.
Use ix86_fp_comparison_strategy.
(ix86_expand_compare): Likewise. Eliminate last two arguments.
(ix86_fp_jump_nontrivial_p): Eliminate.
(ix86_expand_branch): Treat SFmode/DFmode/XFmode as simple. Adjust
call to ix86_expand_compare.
(ix86_split_fp_branch, ix86_expand_setcc,
ix86_expand_carry_flag_compare, ix86_expand_int_movcc,
ix86_expand_fp_movcc): Eliminate code for second jump/bypass jump.
