Bug ID: 15507
Summary: warn about signed, unsigned arithmetic
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++

Classification: Unclassified
It would be nice to have a warning about signed vs. unsigned arithmetic, e.g.
the following:
int s = -1;
unsigned int u = 2;
signed d = u / s;
std::cout << d << std::endl; // prints '0', not '-2' as some might expect.
