Subject: [PATCH 00/13] libstdc++: Add support for running tests with multiple -std options
Date: Mon, 11 Sep 2023 17:16:31 +0100 [thread overview]
Message-ID: <20230911163534.1913512-1-jwakely@redhat.com> (raw)
This patch series replicates the behaviour of the g++ testsuite, so that
libstdc++ tests can easily be run for multiple different -std options in
a single testsuite run. As described in the updated docs, the -std
options to use for every test can be overridden by setting v3_std_list
in ~/.dejagnurc or $DEJAGNU, or setting $GLIBCXX_TESTSUITE_STDS in the
environment. If not overridden, the default is just to run with
-std=gnu++17 (so that we don't increase the time taken for a full
testsuite run).
Tests that require a newer standard than C++17 will default to that
newer standard and C++26, so e.g. std::format tests will be run with
both -std=gnu++20 and -std=gnu++26. This does increase the number of
tests, but only for the subset of tests for C++20/23/26 features. If
this is too costly for testers, we can change that (this might be
needed, because the C++20 tests for std::ranges and std::format are
particularly slow to compile).
Because a correct default will be chosen for tests that require
something newer than C++17, we no longer need dg-options "-std=gnu++20"
or similar in any tests. Removing the explicit -std option allows the
test to be run for later standards via the v3_std_list settings, so that
we can verify that C++20 features still work in C++23 and C++26, for
example. This change already found some tests which failed when run
with a later standard (see r14-3771-gf12e26f3496275).
Patches 2-13 in the series remove those unnecessary dg-options from
about half the relevant tests, but there are more than 500 others that
still need adjusting.
We can remove files like testsuite/std/format/functions/format_c++23.cc
which only exist to duplicate existing tests with a different -std
option. We can remove that file now, and rely on format.cc being run
with multiple -std options by libstdc++ maintainers.
It might also be useful to add a 'make check-quick' target which runs a
small subset of smoke tests with every standard version in v3_std_list.
This would be a suitable target for CI bots and for packagers who want
to verify that a build of GCC is functional, without running the entire
libstdc++ testsuite.
Any comments or suggestions?
