            Bug ID: 46116
           Summary: Failure to optimize `(a + c) < (b + c)` to `a < b`
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Scalar Optimizations
          Assignee: unassignedbugs at nondot.org
          Reporter: gabravier at gmail.com
                CC: llvm-bugs at lists.llvm.org

int f(int a, int b, int c)
{
    return a + c < b + c;
}

This can be optimized to `a < b`. This transformation is done by GCC, but not
by LLVM.
