[cfe-commits] [Patch] Warn about missing parentheses for conditional operator

[Hans Wennborg]

This is an attempt to address some of http://llvm.org/bugs/show_bug.cgi?id=9969

The idea is to warn about code such as:

int foo(int x, bool someCondition) {
return x + someCondition ? 42 : 0;
}

where it seems likely that the programmer forgot that ?: has lower
precedence than +.

The patch looks for condition expressions which are non-boolean binary
operators, implicitly cast to bool, where the right-hand side
expression is bool.

Please take a look!

Thanks,
Hans
