Avoid creation of unnecessary basic_string objects by using a simplified string_view type and performing comparisons on that type instead. A temporary basic_string object is still used when the sub_match's iterators are not contiguous, in order to get an object that the __string_view can reference. * include/bits/regex.h (sub_match::operator string_type): Call str(). (sub_match::compare): Use _M_str() instead of str(). (sub_match::_M_compare): New public function. (sub_match::__string_view): New helper type. (sub_match::_M_str): New overloaded functions to avoid creating a string_type object when not needed. (operator==, operator!=, operator<, operator>, operator<=, operator>=): Use sub_match::_M_compare instead of creating string_type objects. Fix Doxygen comments. * include/bits/regex_compiler.h (__has_contiguous_iter): Remove. (__is_contiguous_normal_iter): Rename to __is_contiguous_iter and simplify. (__enable_if_contiguous_iter, __disable_if_contiguous_iter): Use __enable_if_t. * include/std/type_traits (__enable_if_t): Define for C++11. * testsuite/28_regex/sub_match/compare.cc: New. * testsuite/util/testsuite_iterators.h (remove_cv): Add transformation trait. (input_iterator_wrapper): Use remove_cv for value_type argument of std::iterator base class. From-SVN: r262318 |

README
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.
