Re: RFC: x86 Linux stack alignment requirement

The x86 psABI is very old and doesn't cover XMM registers. I'd like to
update x86 Linux calling convention for XMM register usage. I am not

Maybe you'll want to check how this is handled in Darwin/x86, which requires 16-byte stack alignment because it is internally using XMM registers.
