            Bug ID: 52054
           Summary: Failure to optimize out simple incrementation loop
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Scalar Optimizations
          Assignee: unassignedbugs at nondot.org

int foo()
{
  int u;
  for (int i = 0; i < 510; i++)
    u = i;
  return u;
}

This can be optimized to `return 509;`. GCC does this optimization, but LLVM
does not.
