            Bug ID: 22286
           Summary: Provide strict check for pure attribute
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
          Assignee: kremenek at apple.com
          Reporter: fizzbooze at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Currently an impure function can be attributed as 'pure' and still compile
correctly with no warnings or errors. i.e.:

// BEGIN CODE
int global = 0;

__attribute__((pure))
void foo() {
    global += 1; // this obviously violates the pure attribute
}

int main() {
    foo();
}
// END CODE

It would be nice to be able to enable some sort of warning or error for code
like this.
