        * config/i386/i386.md (*cmpfp0): Remove check for TARGET_80387, this
        check is now implied in X87_FLOAT_MODE_P.

        (unnamed_splitters): Ditto.
        * config/i386/i386.c (function_value_32): Generate FIRST_FLOAT_REG
        for X87_FLOAT_MODE_P mode.  Override FIRST_FLOAT_REG with
        FIRST_SSE_REG for local functions when SSE math is enabled or
        for functions with sseregparm attribute.
        (standard_80387_constant_p): Return -1 if mode is not
        X87_FLOAT_MODE_P.

        (ix86_expand_int_movcc): Check for SCALAR_FLOAT_MODE_P instead
        of FLOAT_MODE_P for cmp_mode and assert that cmp_mode is not
        DECIMAL_FLOAT_MODE_P.
        (ix86_preferred_output_reload_class): Use X87_FLOAT_MODE_P instead
        of SCALAR_FLOAT_MODE_P.
        (ix86_rtx_costs) [PLUS] Remove FLOAT_MODE_P and fall through to ...
        [MINUS]: ... here.  Add SSE_FLOAT_MODE_P and X87_FLOAT_MODE_P
        checks before FLOAT_MODE_P.
        [MULT]: Add SSE_FLOAT_MODE_P and X87_FLOAT_MODE_P checks
        before FLOAT_MODE_P.
