// The calling convention used by MSVC on 32-bit builds will essentially
// disallow functions to have more than 3 XMM/YMM parameters, because it
// will not provide more than 8-byte param alignment, and only the first
// three vector params will be carried in SIMD registers. Now the
// vectorcall convention could probably be problematic in globally visible
// funcitons, but likely not in static ones.
