Performs a set of SIMD multiply-add computation on packed double-precision floating-point values using three
source operands and writes the multiply-add results in the destination operand. The destination operand is also the
first source operand. The second operand must be a SIMD register. The third source operand can be a SIMD
register or a memory location.
VFMADD132PD: Multiplies the two or four packed double-precision floating-point values from the first source
operand to the two or four packed double-precision floating-point values in the third source operand, adds the infinite
precision intermediate result to the two or four packed double-precision floating-point values in the second
source operand, performs rounding and stores the resulting two or four packed double-precision floating-point
values to the destination operand (first source operand).
VFMADD213PD: Multiplies the two or four packed double-precision floating-point values from the second source
operand to the two or four packed double-precision floating-point values in the first source operand, adds the infinite
precision intermediate result to the two or four packed double-precision floating-point values in the third
source operand, performs rounding and stores the resulting two or four packed double-precision floating-point
values to the destination operand (first source operand).
