Summary: clang should warn if 'else if' clause is same as any
previous 'if' clause
Product: new-bugs
Version: trunk
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P

Consider the following C snippit:
if (x == 5)
{
...
}
else if (x == 5)
{
...
}
I've made a typo in the 'else if' and accidentally tested condition.
It would be nice it clang could warn when it sees this.
With raw ints it's easy to see the mistake, but when they are constants, and
two constants accidentally have the same value, it's harder to find.
It would be happy with this in either the compiler or static analyzer.
