This patch provides a plugin callback for invoking selftests, so that a
plugin can add tests to those run by -fself-test=DIR. The callback
invocation uses invoke_plugin_callbacks, which is a no-op if plugin
support is disabled.
gcc/ChangeLog:
* plugin.c (register_callback): Add case for PLUGIN_RUN_SELFTESTS.
(invoke_plugin_callbacks_full): Likewise.
* plugin.def (PLUGIN_RUN_SELFTESTS): New event.
* selftest-run-tests.c: Include "plugin.h".
(selftest::run_tests): Run any plugin-provided selftests.
