I see there are codegen inefficiencies.
Until dmd uses the XMM registers correctly it doesn't make much
sense to add a special calling convetion for this purpose.
I don't agree, because:
- Even if DMD codegen is far from not perfect, it's a good idea
to improve all things in parallel. Generally improving things (or
fixing bugs) gives a better result if you adopt a pipelined
development approach.
- A vector calling convention is meant to be usable on other
compilers too, like LDC2, that have better codegen. (The asm I
have shown in this thread comes from LDC2 because dmd doesn't
even use SIMD registers on Windows 32 bit).
