I thought I'd add some unit tests to make sure gdb::optional behaved correctly, and started writing some, but then thought/realized that libstdc++ already has extensive testing for C++17 std::optional, which gdb::optional is a subset of, and thought why bother writing something from scratch. So I tried copying over a subset of libstdc++'s tests (that ones that cover the subset supported by gdb::optional), and was positively surprised that they mostly work OOTB. This did help shake out a few bugs from what I was implementing in the previous patch to gdb::optional. Still, it's a good chunk of code being copied over, so if people dislike this copying/duplication, I can drop this patch. gdb/ChangeLog: 2017-04-18 Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/optional-selftests.c.
