instr_compute_address_ex() may need support for xsave area address(es).

instr_compute_address_ex() may need to compute the xsave user state component addresses, unless it returns only the xsave area's start address. If the former, it can read the instruction's user state component mask in edx:eax.

In this context, "user state component addresses" above means the individual addresses of the individual components in the xsave area as written by the instruction.
