serious bugs in Altivec implementation of gcc

[Eyal Bagon]

hello
The max patch is working - thanks.
The problem with vec_msum still exist, the same problem occurs when I 
use vec_vmsummbm instead of vec_msum - could the problem be somewhere in 
the implementation of __builtin_altivec_vmsummbm ? ( by the way the 
altivec.h file you send me is the same as I had )

another thing that I noticed when comparing assembler code of 2 
corresponding files it looks like the new gcc code is less optimised
( I attached the testMax_2.9.2.cpp and testMax_3.2.cpp and their 
corresponding assembler files.

I used : g++ -S -Wall -pedantic -ansi -Wno-long-long -DNDEBUG -O6 
-DALTIVEC -fvec testMax_2.9.2.cpp

and : g++ -S -Wall -pedantic -ansi -Wno-long-long -DNDEBUG -O6 -DALTIVEC 
-maltivec testMax_3.2.cpp

Thanks
Eyal
