Add selftests run filtering
With the growing number of selftests, I think it would be useful to be able to run only a subset of the tests. This patch associates a name to each registered selftest. It then allows doing something like: (gdb) maintenance selftest aarch64 Running self-tests. Running selftest aarch64-analyze-prologue. Running selftest aarch64-process-record. Ran 2 unit tests, 0 failed or with gdbserver: ./gdbserver --selftest=aarch64 In both cases, only the tests that contain "aarch64" in their name are ran. To help validate that the tests you want to run were actually ran, it also prints a message with the test name before running each test. Right now, all the arch-dependent tests are registered as a single test of the selftests. To be able to filter those too, I made them "first-class citizen" selftests. The selftest type is an interface, with different implementations for "simple selftests" and "arch selftests". The run_tests function simply iterates on that an invokes operator() on each test. I changed the tests data structure from a vector to a map, because - it allows iterating in a stable (alphabetical) order - it allows to easily verify if a test with a given name has been registered, to avoid duplicates There's also a new command "maintenance info selftests" that lists the registered selftests. gdb/ChangeLog: * common/selftest.h (selftest): New struct/interface. (register_test): Add name parameter, add new overload. (run_tests): Add filter parameter. (for_each_selftest_ftype): New typedef.

(maintenance_info_selftests): New function. (_initialize_maint_cmds): Register "maintenance info selftests" command. Update "maintenance selftest" doc. * regcache.c (_initialize_regcache): Add names when registering selftests. * rust-exp.y (_initialize_rust_exp): Likewise. * selftest-arch.c (gdbarch_selftest): New struct. (gdbarch_tests): Remove. (register_test_foreach_arch): Add name parameter. Call register_test. (tests_with_arch): Remove, move most content to gdbarch_selftest::operator().
