In further discussion of possible resolutions, we discovered that we can avoid that change while still getting the desired behavior on overload-conv-3.C by making this a tiebreaker after comparing conversions, rather than before. This also simplifies the implementation. The issue resolution has not yet been finalized, but this seems like a clear improvement. DR 2327 PR c++/86521 gcc/cp/ChangeLog: * call.cc (joust_maybe_elide_copy): Don't change cand. (joust): Move the elided tiebreaker later. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/overload-conv-4.C: Remove warnings. * g++.dg/cpp1z/elide7.C: New test.
