Subject: [Bug tree-optimization/33953] [4.3 regression] internal compiler error: vector VEC(tree,base) index domain error, in vectorizable_operation at tree-vect-transform.c:4017
Date: Wed, 31 Oct 2007 10:57:00 -0000	[thread overview]
Message-ID: <20071031105706.31727.qmail@sourceware.org> (raw)

------- Comment #5 from irar at il dot ibm dot com  2007-10-31 10:57 -------
The problem here is that more than one vector stmts are used to vectorize (SLP)
this loop, while only one vector operand is created in case of vector shift
with scalar argument.

I am preparing a patch.

Thanks,
Ira
