I discovered that the template typedef access check was rather more expensive than needed. The call of get_types_needed_access_check in the FOR_EACH_VEC_SAFE_ELT is the moral equivalent of 'for (size_t pos = 0; pos != strlen (string); pos++)'. Let's not do that. * pt.c (perform_typedefs_access_check): Cache expensively calculated object references. (check_auto_in_tmpl_args): Just assert we do not get unexpected nodes, rather than silently do nothing. (append_type_to_template_for_access): Likewise, cache expensie object reference.
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.
