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.
