[LLVMdev] Help adding the Bullet physics sdk benchmark to the LLVM test suite?
...aint
solver: http://tinyurl.com/ydoapct
Some developers replaced some linear algebra functions (in
Bullet/LinearMath) with VFP/Neon
optimizations, but haven't contributed this back.
This NEON/VFP, part of the an open source iPhone project, could be a
starting point for this:

...ON), you could contribute it back to Bullet?
I believe this should work as-is on linux. Am I missing something?

Very unfortunate it's using inline asm. Are there developers should are interested in using NEON intrinsics?

Well, I doubt so, unfortunately - LLVM does not have any autopar these days

Ok. What's about Linux builds? Are there any other implementations
e.g.

Hi Anton,
Thanks a lot for offering help.
Bullet uses basic linear algebra with 4-way vectors, quaternion and
matrices.
Although most of this is plain portable C++ perhaps LLVM can auto-vectorize
some of this?
There is a little bit of hand optimized x86 SSE code. This is only enabled
on 32bit Windows and Mac OSX Intel builds.

If you are interested,
