Bug ID: 43809
Summary: Missing unused variable and needless cast warning
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],

Given:
struct S
{
S(int value)
: m_value(value) {}
int m_value;
};
void foo() {
S x{S{10}};
S y{10};
}
When compiling with -Weverything, I would have expected:
- unused variable x (available)
- unused variable y (available only when making it constexpr)
- useless cast within x (missing)
