I'm really excited to see this merged in! Props on all involved

question 1: Will this be included in the upcoming 7.8 release?

Yes, that's the plan!

question 2: I see that some of the useful (albeit specialized) SSE primops aren't included, though it looks like adding them (at least for platforms that support them) would be largely mechanical..... If adding those primops is something GHC HQ would welcome (ignoring the sorting out the whole supporting SSE2 vs full AVX discussion), I'm more than happy to spend some time turning the crank to add those primops.

I'd like to figure out how to properly support having the set of available primops depend on the dynamic flags before adding too much more. I'll be speaking to Simon PJ about it tomorrow. Do you have specific needs for any missing primops? If so, I'd like to know---customers are good :) We talked a while ago about you possibly cooking up some sample programs that needed SSE instructions. Have there been any recent developments? Thanks, Geoff

As an aside, what's the proper way for me to test the ARM cross-compilation support? I'm afraid my patches may break things there.

I've seen you've merged your changes into mainline so I've done a build of GHC HEAD on my arm/linux and it's gone fine so you've not broken anything -- at least from the build perspective.

Thanks, Karel

Thanks for the confirmation. I followed the instructions for building the Raspberry Pi cross GHC and tested the simd branch before I merged, but I'm glad to know I didn't break anything obvious for you either!
