For some reason the type printer for std::string doesn't work in C++20 mode, so std::basic_string<char, char_traits<char>, allocator<char> is printed out in full rather than being shown as std::string. It's probably related to the fact that the extern template declarations are disabled for C++20, but I don't know why that affects GDB. For now I'm just marking the relevant tests as XFAIL. That requires adding support for target selectors to individual GDB directives such as note-test and whatis-regexp-test. libstdc++-v3/ChangeLog: * testsuite/lib/gdb-test.exp: Add target selector support to the dg-final directives. * testsuite/libstdc++-prettyprinters/80276.cc: Add xfail for C++20. * testsuite/libstdc++-prettyprinters/libfundts.cc: Likewise. * testsuite/libstdc++-prettyprinters/prettyprinters.exp: Tweak 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.
