I will add -fgraphite-identity to the testcase as otherwise we're not going to
test graphite on trunk...

Tobias,
Please fix the testcase before committing to trunk, like this ('return 0' is
needed to ensure the test does not fail when compiled correctly; 'noclone' to
ensure that foo is not specialized for n=0):
/* { dg-options -O2 -fno-tree-ch } */
#include vector
using std::vector;
vectorunsigned __attribute__((noinline,noclone)) foo(unsigned n)
{
vectorunsigned *vv = new vectorunsigned(n, 0u);
return *vv;
}
int main()
{
foo(0);
return 0;
}

It needs just some cleanup, a nice description and all this stuff. The problem was that we check the loop conditions only after the loop body, so loops with zero iterations are executed once. And this is one time too much. I will do the cleanup and committing of this patch next week -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42130
