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. altivec / NEON ?

Ok, will do.

So far 32 and 64 bit Linux and MacOS, 32-bit ppc/darwin. Also, there
is special "small" mode mainly designed for stuff like ARM.
It will be nice (in theory) to have some NEON/VFP code, since the
testsuite currently lacks any beanchmark for this.
