Subject: [pushed] c++: auto member function and auto variable [PR106893]
Date: Mon, 12 Sep 2022 15:46:46 -0400 [thread overview]
Message-ID: <20220912194646.3441845-1-jason@redhat.com> (raw)
As with PR105623, we need to call mark_single_function sooner to
resolve the type of a BASELINK.
Tested x86_64-pc-linux-gnu, applying to trunk.
PR c++/106893
PR c++/90451
gcc/cp/ChangeLog:
* decl.cc (cp_finish_decl): Call mark_single_function.
gcc/testsuite/ChangeLog:
* g++.dg/cpp1y/auto-fn65.C: New test.
