It looks cleaner if we can use a vec* directly as a range for the C++11 range-based 'for' loop, without needing to indirect from it, and also works with null pointers. The change in cp_parser_late_parsing_default_args is an example of how this can be used to simplify a simple loop over a vector. Reverse or subset iteration will require adding range adaptors. I deliberately didn't format the new overloads for etags since they are trivial. gcc/ChangeLog: * vec.h (begin, end): Add overloads for vec*. * tree.c (build_constructor_from_vec): Remove *. gcc/cp/ChangeLog: * decl2.c (clear_consteval_vfns): Remove *. * pt.c (do_auto_deduction): Remove *. * parser.c (cp_parser_late_parsing_default_args): Change loop to use range 'for'.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
