--- Comment #3 from Jason Merrill <jason at gcc dot gnu.org> 2011-06-17 20:08:06 UTC --- Author: jason Date: Fri Jun 17 20:08:01 2011 New Revision: 175158 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=175158 Log: PR c++/43912 Generate proxy VAR_DECLs for better lambda debug info. * cp-tree.h (FUNCTION_NEEDS_BODY_BLOCK): Add lambda operator(). (LAMBDA_EXPR_PENDING_PROXIES): New. (struct tree_lambda_expr): Add pending_proxies. * name-lookup.c (pushdecl_maybe_friend_1): Handle capture shadowing. (qualify_lookup): Use is_lambda_ignored_entity. * parser.c (cp_parser_lambda_expression): Don't adjust field names. Call insert_pending_capture_proxies. (cp_parser_lambda_introducer): Use this_identifier. (cp_parser_lambda_declarator_opt): Call the object parameter of the op() "__closure" instead of "this". (cp_parser_lambda_body): Call build_capture_proxy. * semantics.c (build_capture_proxy, is_lambda_ignored_entity): New. (insert_pending_capture_proxies, insert_capture_proxy): New. (is_normal_capture_proxy, is_capture_proxy): New. (add_capture): Add __ to field names here, return capture proxy. (add_default_capture): Use this_identifier, adjust to expect add_capture to return a capture proxy. (outer_lambda_capture_p, thisify_lambda_field): Remove. (finish_id_expression, lambda_expr_this_capture): Adjust. (build_lambda_expr): Initialize LAMBDA_EXPR_PENDING_PROXIES. * pt.c (tsubst_copy_and_build): Check that LAMBDA_EXPR_PENDING_PROXIES is null.
