           Summary: clang generates wrong AST/code for compound assignment
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sharparrow1 at yahoo.com

Per subject; a couple of testcases:

unsigned char a,b; void c(void) {a <<= b;} void d(void) {a /= b;}

The issue is that the functions for computing the types skip unary promotions
for compound assignments.  I'm not sure what the cleanest way to solve this is,
