            Bug ID: 15420
           Summary: redundant warning when trying to apply operator== on
                    values of uncomparable types
           Product: clang
           Version: trunk
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: M8R-9yw8a5 at mailinator.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

1. Source code:

struct A { };

int main()
{
    A a;
    return a == a;
}

2. Actual output (slimmed):

warning: self-comparison always evaluates to true
error: invalid operands to binary expression ('A' and 'A')

3. Expected output:

error: invalid operands to binary expression ('A' and 'A')

(ie., no warning)
