        * config/i386/i386.c (ix86_prepare_fp_compare_args): Do not
        force operand 0.0 into register in XFmode. Also do not force

        * config/i386/i386.md (*cmpfp_0): Delete. Remove comment.
        (*cmpfp_0_sf, cmpfp_0_df, cmpfp_0_xf): New patterns to
        implement ftst x87 instruction.
