            Bug ID: 45488
           Summary: implement -Wunused-but-set-variable
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

Clang doesn't warn on:

void foo(int x) {
    int a = 0;
    if (x)
        a = 1;
}

GCC warns with -Wunused-but-set-variable:
warning: variable 'a' set but not used [-Wunused-but-set-variable]
