| Parameter | Description |
|---|---|
| a | Vector a |
| b | Vector b |
| imm8 | imm8 |
v256 Vector
Compare packed double-precision (64-bit) floating-point elements in a and b based on the comparison operand specified by imm8, and store the results in dst.
____ VCMPPD ymm1, ymm2, ymm3/v256, imm8 Performs an SIMD compare of the four packed double-precision floating-point values in the second source operand (third operand) and the first source operand (second operand) and returns the results of the comparison to the destination operand (first operand). The comparison predicate operand (immediate) specifies the type of comparison performed on each of the pairs of packed values.
