I have seen support for autovectorisation on the x86 platform but what about the PPC platform with Altivec, any boost would be nice ;)

Autovectorization in its current stage is not very useful. It can handle only some simple cases and speed gain is debatable.

We tested it a bit, overall it should be turned off (gcc-4.1.1).

The good way to use it is set the verbose level high and use the log and the profiler log to see which places are more promising or more easy to vectorize by hand

Altivec is going to become an important part of what we educate the market about in terms of POWER and Power.org.

As soon as Konstantinos is back we will get started again:
