Bug ID: 89883
Summary: Excessive candidates for ambiguous overload in error
message
Product: gcc
Version: 8.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: joerg.rich...@pdv-fs.de
Target Milestone: ---
This code:
#include <ostream>
enum Foo
{
Bar
};
std::ostream operator<<( std::ostream& os, Foo );
std::ostream operator<<( std::ostream& os, Foo const& );
void func( std::ostream& os )
{
os << Bar;
}
Generates around 70 lines of error message.
But in this case there are really only 2 conflicting overloads. One for 'Foo'
and one for 'Foo const&'. They both match better than any other overload.
Can GCC output just the two more matching overloads in this case?
