Given an invocation context block and SSE (Streaming SIMD
Extensions) register index such that 0 <= index < 16, copy the
register value to ymm_copy. For example, an index value of 4
fetches the value, which represents the contents of ymm4.
LIB$X86_GET_YMM returns failure status if there is no
corresponding XSAVE area in the invo_context or if the index
represents a register or register set not saved in the XSAVE
area.
Format
