Re: [eigen] [PATCH] preliminary AltiVec support

[Benoît Jacob <jacob@xxxxxxxxxxxxxxx>]

Thanks a lot, committed.

I don't have AltiVec hardware to test on, however.

I think the arch-specific code (in PacketMath.h) should be split into 
arch-specific files, and you should get copyright on the AltiVec path you 
added.

Cheers,

Benoit
