For "foo(|" [1] we requested a completion from libclang with the cursor position just before "foo" and then filtered the function declarations for functions matching the name "foo". This worked fine for ordinary functions, but obviously not for constructors and functors. Recent versions of libclang support proper function call completion with XCursor_OverloadCandidate, so make use of that. [1] '|' represents the cursor position Task-number: QTCREATORBUG-14882 Task-number: QTCREATORBUG-14884 Change-Id: I9d31b3960ccff6a8b9440dbcb7ff9f5ca9f61266 Reviewed-by: Tim Jenssen <tim.jenssen@qt.io>
