Compares packed 128-bit and 256-bit float64 vector elements. The corresponding Intel® AVX instruction is
- float64 vector used for the operation
- float64 vector also used for the operation
- an immediate operand that specifies the type of comparison to be performed of the packed values; seeimmintrin.hfile for the values to specify the type of comparison
Performs a SIMD compare of the four packed double-precision floating-point (float64) values in the first source operand,
m1, and the second source operand,
m2, and returns the results of the comparison.
_mm_cmp_pdintrinsic is used for comparing 128-bit float64 values while the
_m256_cmp_pdintrinsic is used for comparing 256-bit float64 values.
predicateparameter (immediate) specifies the type of comparison performed on each of the pairs of packed values.
Result of the compare operation.
