    • Introduce pretty_printer::clone vfunc · 368877a1 
      This patch provides a way to clone a pretty_printer.

This is needed so that we can capture text in a label_text and make
layout decisions based on it, using the policy of global_dc's printer,
whilst within a call to diagnostic_show_locus.  We can't print with
the pretty_printer itself within a call to diagnostic_show_locus since
it has partly-buffered content.

gcc/c-family/ChangeLog:
	* c-pretty-print.c (c_pretty_printer::clone): New vfunc
	implementation.
	* c-pretty-print.h (c_pretty_printer::clone): New vfunc decl.

    • PR c++/92878 - Parenthesized init of aggregates in new-expression. · c20f7e99 
      Ville pointed out that our paren init of aggregates doesn't work for

  auto a = new A(1, 2, 3);

and I think it should:

A new-expression that creates an object of type T initializes that object
as follows:
...
-- Otherwise, the new-initializer is interpreted according to the
   initialization rules of [dcl.init] for direct-initialization.

so I think it follows that we should perform dcl.init#17.6.2.2.

This doesn't work with new[]; we have:
  error ("parenthesized initializer in array new");

	* init.c (build_new_1): Handle parenthesized initialization of
	aggregates in new-expression.

	* g++.dg/cpp2a/paren-init20.C: New test.

    • PR c++/92105 - decltype(decltype) error cascade. · 7ae01728 
      The primary change here is to do the CPP_DECLTYPE replacement even when we
get an error, so we don't keep trying and giving the same parse error each
time.  We also commit to the tentative firewall parse more often, leading to
better diagnostics.

	* parser.c (cp_parser_decltype_expr): Don't tentative_firewall here.
	(cp_parser_decltype): Do it here.  Remember a non-tentative error.

    • PR c++/57082 - new X{} and private destructor. · 0e5def81 
      build_new_1 already passes tf_no_cleanup to build_value_init, but in this
testcase we end up calling build_value_init by way of
build_special_member_call, so we need to pass it to that function as well.

	* init.c (build_new_1): Also pass tf_no_cleanup to
	build_special_member_call.
