Yes, I have backports prepared for 5, 6, and 7.  Waiting a short time before
applying those.

Thanks!

So fixed on the trunk so far?  Any plans for 7.x backport?

--- Comment #2 from Bill Schmidt  ---
The "altivec_vsumsws" pattern for little endian isn't working as intended. 
This needs to be rewritten.  So does the "altivec_vsum2sws" pattern.  I'll work
on a patch early next week.
