VEXTRACTF64x2

Extracts two 64-bit floating-point values from a 128-bit YMM register and stores them into a XMM register.

The following table describes the supported source and destination operands.

DO NOT support LOCK

This instruction is available only in 64-bit mode. It requires AVX support.

To avoid undefined behavior or exceptions, ensure that the immediate operand is within the valid range for the specified register size; however, for VEXTRACTF64x2, the index is typically implicit or handled via specific AVX encoding. Using this instruction in 32-bit mode will result in an invalid opcode exception.
