http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58549 --- Comment #6 from abutcher at gcc dot gnu.org --- Author: abutcher Date: Tue Nov 12 20:17:33 2013 New Revision: 204714 URL: http://gcc.gnu.org/viewcvs?rev=204714root=gccview=rev Log: Refactor implicit function template implementation and fix 58534, 58536, 58548, 58549 and 58637. gcc/ * tree.c (grow_tree_vec_stat): New function ... * tree.h (grow_tree_vec_stat) (grow_tree_vec): ... and its declaration and macro front-end. gcc/cp/ PR c++/58534 PR c++/58536 PR c++/58548 PR c++/58549 PR c++/58637 * parser.h (struct cp_parser): New members implicit_template_parms, implicit_template_scope and auto_is_implicit_function_template_parm_p. * parser.c (add_implicit_template_parms): Refactor as ... (synthesize_implicit_template_parm): ... this to append a new template type parm to the current template parameter list (introducing a new list if necessary). Removed push_deferring_access_checks. (finish_fully_implicit_template): Removed pop_deferring_access_checks. (cp_parser_new): Initialize new cp_parser members. (cp_parser_parameter_declaration_clause): Consider auto as implicit template parm when parsing a parameter declaration (unless parsing an explicit specialization). (cp_parser_parameter_declaration_list): Remove local implicit_template_parms counter and reset cp_parser implicit template state when complete. (cp_parser_lambda_expression): Reset implicit template cp_parser members whilst generating lambda class. (cp_parser_function_definition_after_declarator): Reset implicit template cp_parser members whilst parsing function definition. (make_generic_type_name): Respell 'autoN' as 'auto:N' which works better with template diagnostics. (cp_parser_simple_type_specifier): Synthesize implicit template parm on parsing 'auto' if auto_is_implicit_function_template_parm_p and provide diagnostics ... * decl.c (grokdeclarator): ... that were previously done here. gcc/testsuite/g++.dg/ * cpp1y/pr58534.C: New testcase. * cpp1y/pr58536.C: New testcase. * cpp1y/pr58548.C: New testcase. * cpp1y/pr58549.C: New testcase. * cpp1y/pr58637.C: New testcase.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58549 --- Comment #2 from Volker Reichelt reichelt at gcc dot gnu.org --- To me they look like a (syntactically simpler) alternative to template parameters. They were introduced here: 2013-09-16 Adam Butcher a...@jessamine.co.uk * cp-tree.h (type_uses_auto_or_concept): Declare. (is_auto_or_concept): Declare. * decl.c (grokdeclarator): Allow 'auto' parameters in lambdas with -std=gnu++1y or -std=c++1y or, as a GNU extension, in plain functions. [...]
