* config/i386/sse.md (fmai_vmfmadd_<mode>): Use (match_dup 1)
|
|
instead of (match_dup 0) as second argument to vec_merge.
|
|
(*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.
