| Parameter | Description |
|---|---|
| a | Vector a |
| b | Vector b |
| imm8 | imm8 |
v128 Vector
Compare the lower single-precision (32-bit) floating-point element in a and b based on the comparison operand specified by imm8, store the result in the lower element of dst, and copy the upper 3 packed elements from a to the upper elements of dst.
____ VCMPSS xmm1, xmm2, xmm3/m64, imm8 Compares the low single-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 operand) specifies the type of comparison performed. For compare predicate values in range 0-7 compiler may generate SSE2 instructions if it is warranted for performance reasons.
