(*fmai_fmadd_<mode>, *fmai_fmsub_<mode>): Likewise. Remove third alternative. (*fmai_fnmadd_<mode>, *fmai_fnmsub_<mode>): Likewise. Negate operand 2 instead of operand 1, but put it as first argument of fma. * config/i386/fmaintrin.h (_mm_fnmadd_sd, _mm_fnmadd_ss, _mm_fnmsub_sd, _mm_fnmsub_ss): Negate the second argument instead of the first.
