Confirmed. Reduced testcase that crashes on i686-pc-linux-gnu when compiled
with "-msse -O" (as C or C++ code):
======================================================
typedef int v4i __attribute__((vector_size(16)));
void foo(v4i* p, v4i v)
{
int i;
for (i=0; i < 4; ++i)
*p += v;
}
======================================================
bug.c: In function 'foo':
bug.c:8: internal compiler error: in expand_simple_binop, at optabs.c:1157
Please submit a full bug report, [etc.]
The bug appeared in GCC 4.2.0 and disappeared on mainline between
2007-09-14 and 2007-10-13.
