(regex_search<>): Move the search logic to regex_executor. * include/bits/regex_automaton.h: Add some new _Opcode. Refactor _NFA::_M_insert_*. * include/bits/regex_automaton.tcc: Add DEBUG dump for new _Opcode. Refactor _NFA::_M_insert_*. * include/bits/regex_compiler.h (_Compiler<>::_M_get_nfa): Use make_shared instead of construct by hand. * include/bits/regex_compiler.tcc: Implement _Compiler<>::_M_assertion. * include/bits/regex_constants.h: Fix indentation and line breaking. * include/bits/regex_executor.h: Add _ResultsEntry to support greedy/ungreedy mode. Move regex_search logic here. * include/bits/regex_executor.tcc: Implement assertions and greedy/ungreedy matching. * include/bits/regex_scanner.h: Add a new token _S_token_ungreedy. * include/bits/regex_scanner.tcc: Parse a new token _S_token_ungreedy. * testsuite/28_regex/algorithms/regex_search/ecma/assertion.cc: New. * testsuite/28_regex/algorithms/regex_search/ecma/greedy.cc: New. * testsuite/28_regex/algorithms/regex_search/ecma/string_01.cc: Fix comment.

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.
