libstdc++: Make std::random_device throw more std::system_error [PR105081]
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.
