[Bug tree-optimization/44507] [4.5/4.6 Regression] vectorization ANDs array elements together incorrectly

[irar at il dot ibm dot com]

------- Comment #5 from irar at il dot ibm dot com  2010-06-13 10:29 -------
The bug is in creation of a neutral value for BIT_AND_EXPR. What is the correct
way to create it for all types? I found 
double-int.h:#define ALL_ONES (~((unsigned HOST_WIDE_INT) 0))
but it won't work for signed.

Thanks,
Ira
