Getting the following testsuite failures on ppc-linux:
FAIL: gcc.dg/vect/vect-20.c execution test
FAIL: gcc.dg/vect/vect-20.c scan-tree-dump-times vectorized 3 loops 1
FAIL: gcc.dg/vect/vect-22.c execution test

These testcases actually fail even with vectorization disabled - it aborts when 
checking that the results for the code that operates on the char arrays are  
correct (arrays ca, cb). Changing these arrays to "signed char" fixes the 
problem. i.e:

35,46c35,46
<   char ca[N];
<   char cb[N] =
---
>   signed char ca[N];
>   signed char cb[N] =

will submit a patch along these lines shortly.
