VEXTRACTI32x4

VEXTRACTI32x4 extracts four 32-bit doublewords from a 256-bit vector register, based on an immediate index, and stores the result in a 128-bit vector register.

The following table covers what the source and destinations can be:

DO NOT support LOCK

This instruction is available only in 64-bit mode or compatibility mode. It requires the AVX instruction set to be enabled.

The immediate index SHALL be in the range 0 to 3. If the source is a 128-bit register (xmm), the index MUST be 0; otherwise, the behavior is undefined. The destination register is treated as a 128-bit vector, and any bits beyond the 128-bit boundary in the destination register are undefined.
