From: Alexandre Oliva <aoliva@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc(refs/users/aoliva/heads/testme)] libstdc++: xfail experimental/net tests on rtems Date: Mon, 27 Jun 2022 09:33:12 +0000 (GMT) [thread overview] Message-ID: <20220627093312.B9686384188D@sourceware.org> (raw) https://gcc.gnu.org/g:7da2378aaa5638d89b8404841cfafdc1cbc027e9 commit 7da2378aaa5638d89b8404841cfafdc1cbc027e9 Author: Alexandre Oliva <oliva@adacore.com> Date: Mon Jun 27 05:30:44 2022 -0300 libstdc++: xfail experimental/net tests on rtems Some net/timer/waitable tests fail on rtems because poll() is not available. The above, as well as net/internet/resolver/ops tests and net/timer/waitable/cons.cc, will fail early at runtime unless mkfifo is enabled in the RTEMS configuration, because the io_context ctor throws when pipe() fails. However, even enabling pipes and adjusting the net_ts link command to use --gc-sections for -lbsd as recommended, both net/internet/resolver/ops still fail at runtime. for libstdc++-v3/ChangeLog * testsuite/lib/dg-options.exp (add_options_for_net_ts): Add -Wl,--gc-sections for RTEMS targets. * testsuite/experimental/net/timer/waitable/dest.cc: Link-time xfail on RTEMS. * testsuite/experimental/net/timer/waitable/ops.cc: Likewise. * testsuite/experimental/net/internet/resolver/ops/lookup.cc: Execution-time xfail on RTEMS. * testsuite/experimental/net/internet/resolver/ops/reverse.cc: Likewise.
