* config/i386/i386-protos.h (ix86_split_fp_branch): New rtx
        argument.

        * config/i386/i386.c (output_fp_compare): Fix is_sse condition.
        Use EFLAGS_P only when fcomi insn should be used. Fix handling
        of eflags_p variable. Change alt table accordingly. For non-fcomi
        compare insn always use trailing fnstsw insn. Fix intmode
        calculation for ficom insn.
        (ix86_split_fp_branch): Add "rtx pushed" as new parameter. Call
        ix86_free_from_memory when "pushed" is specified.
        (ix86_expand_branch): Change call to ix86_split_fp_branch.

        * config/i386/i386.md (*cmpfp_0_sf, *cmpfp_0_df, *cmpfp_0_xf):
        Change eflags_p parameter in call to output_fp_compare.
        (*cmpfp_2_sf, *cmpfp_2_df, *cmpfp_2_xf): Remove.
        (*cmpfp_2_sf_1, *cmpfp_2_df_1, *cmpfp_2_xf_1): Rename to
        *cmpfp_2_sf, *cmpfp_2_df, *cmpfp_2_xf.  Change eflags_p
        parameter in call to output_fp_compare.
        (*cmpfp_2_u): Remove.
        (*cmpfp_2_u_1): Rename to *cmpfp_2_u. Change eflags_p parameter
        in call to output_fp_compare.
        (*ficom_1): Remove insn definition and corresponding define_split.
        (*cmpfp_si): New insn definition.
        (*fp_jcc_8): New insn definition. Add new splitters for
        "memory_operand" and "register_operand".
        (define_split): Add new parameter in call to ix86_split_fp_branch.

        config/i386/predicates.md (float_operator): New predicate.
