In the event that the host doesn't support the requirements for running AVX-enabled applications (SVE2 with at least 256-bit wide vectors) but still wanted to run regular SSE-enabled applications, they would be taking a performance hit due to a load/store pessimization (necessary in order for 256-bit loads/stores to work) However, we can add an alternate view into the xmm data that would allow those hosts to use the previous optimization, while still supporting AVX-capable hosts.
