Bug ID: 48252
Summary: Adding an operator== breaks implicit operator==
generation from defaulted <=>
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: C++2a
Assignee: unassignedclangb...@nondot.org
Reporter: barry.rev...@gmail.com
CC: blitzrak...@gmail.com, erik.pilking...@gmail.com,
llvm-bugs@lists.llvm.org, richard-l...@metafoo.co.uk
Reduced example:
#include <compare>
struct X
{
auto operator<=>(X const&) const = default;
auto operator==(int i) const;
};
bool f(X x) {
return x == x;
}
clang trunk rejects this saying no matching candidate. The presence of the
unrelated operator== seems to prevent the generation of X::operator==(X const&)
const from the defaulted <=>.
