c++: ICE with auto in template arg [PR110065]
Here we started crashing with r14-1659 because that removed the
auto checking in cp_parser_template_type_arg which seemed like
dead code. But the attached test shows that the code can still
be reached because cp_parser_type_id_1 checks auto only when
auto_is_implicit_function_template_parm_p is on.
Then I noticed that we're still crashing in C++20, and that ICE
started with r12-4772. So I changed the reemerged check to use
flag_concepts_ts rather than flag_concepts on the basis that
check_auto_in_tmpl_args also checks flag_concepts_ts.
PR c++/110065
gcc/cp/ChangeLog:
* parser.cc (cp_parser_template_type_arg): Add auto checking.
gcc/testsuite/ChangeLog:
* g++.dg/concepts/auto8.C: New test.
* g++.dg/concepts/auto8a.C: New test.
