--- Comment #1 from Agner Fog <agner at agner dot org> ---
I can confirm that both Clang, MS, and Intel compilers transfer vectors in
registers for function parameters and function return in 64 bit Windows when
__vectorcall is specified. There is still 32 or 40 bytes of superfluous shadow
space allocated on the stack.
Clang adds @@<size> to the mangled function name.
Please support __vectorcall in Gcc as well.
