Is there any plan to add vectorisation intrinsics to DMD?
I know that DMD generates vectorised instructions for array
operations, but last time I checked, these were far from optimal for
aligned float[4] objects. In fact, it appears to generate a function
call for all vector operations, regardless of size or alignment.
I believe that these intrinsics would be very beneficial to D, and
this is because I believe that one of D's biggest markets is indie
game devs:
- They need a really high performance language, but are tired of C++
- They are not held back by legacy code
- They are generally risk takers, so are willing to invest in new tech
A lack on vector intrinsics in DMD gives them an extra reason to stick
with C++.
I agree with everything you said. I think D's array op syntax form a
sound basis for doing vector ops, and plan on doing them.
Are those swizzling ops part of the topic?
