In r14-289-gf9412cedd6c0e7 I made the std::random_device constructor throw std::system_error for unrecognized tokens. But it still throws std::runtime_error for a token such as "rdseed" that is recognized but not supported at runtime by the CPU the program is running on. With this change we throw std::system_error for those cases too. This fixes the following failures on Intel CPUs withour rdseed support: FAIL: 26_numerics/random/random_device/94087.cc execution test FAIL: 26_numerics/random/random_device/cons/token.cc execution test FAIL: 26_numerics/random/random_device/entropy.cc execution test libstdc++-v3/ChangeLog: PR libstdc++/105081 * src/c++11/random.cc (random_device::_M_init): Throw std::system_error when the requested device is a valid token but not available at runtime. |

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.
