We had a few times the need for a data structure that does essentially what C++17's std::string_view does, which is to give an std::string-like interface (only the read-only operations) to an arbitrary character buffer. This patch adapts the files copied from libstdc++ by the previous patch to integrate them with GDB. Here's a summary of the changes: * Remove things related to wstring_view, u16string_view and u32string_view (I don't think we need them, but we can always add them later). * Remove usages of _GLIBCXX_BEGIN_NAMESPACE_VERSION and _GLIBCXX_END_NAMESPACE_VERSION. * Put the code in the gdb namespace. I had to add a few "std::" in front of std type usages. * Change __throw_out_of_range_fmt() for error(). * Make gdb::string_view an alias of std::string_view when building with >= c++17. * Remove a bunch of constexpr, because they are not valid in c++11 (e.g. they are not a single return line). * Use std::common_type<_Tp>::type instead of std::common_type_t<_Tp>, because c++11 doesn't have the later. * Remove the #pragma GCC system_header, since that silences some warnings that we might want to have if we're doing something not correctly. * Remove operator ""sv. It would need a lot of work to make all supported compilers happy, and we can easily live without it. * Remove operator<<. It is implemented using __ostream_insert (a libstdc++ internal). Bringing it in might be possible, but I don't think that would be worth the effort, since we don't really use streams at the moment. * Replace internal libstdc++ asserts ( __glibcxx_assert and __glibcxx_requires_string_len) with gdb_assert. * Remove hash helpers, because they use libstdc++ internal functions. If we need them we always import them later. The string_view class in cli/cli-script.c is removed and its usage replaced with the new gdb::string_view. gdb/ChangeLog: * common/gdb_string_view.h: Remove libstdc++ implementation details, adjust to gdb reality. * common/gdb_string_view.tcc: Likewise. * cli/cli-script.c (struct string_view): Remove. (user_args) <m_args>: Change element type to gdb::string_view. (user_args::insert_args): Adjust. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
