Bug ID: 40264
Summary: Doesn't warn about the unused variable
Product: clang
Version: 7.0
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: [email protected]

In this code
---begin test.cpp---
bool x(bool y) {
return !y;
}
void f() {
bool b = false;
b |= x(false);
b |= x(true);
}
---end test.cpp---
the variable 'b' in 'f' is computed but isn't used, but clang++70 doesn't warn
about this when -Wall is set.
