The register_test_foreach_arch is used to instantiate a given selftest
for all architectures supported by GDB. It is used in many _initialize_*
functions (under initialize_all_files, called by gdb_init).
Because the call is done during GDB's initialization, and because there
is no guaranty about the order in which all the _initialize_* functions
are executed, when register_test_foreach_arch is called, GDB is not
fully initialized. Specifically, when a particular initialize function
is executed, only the architectures registered at that point are listed
by gdbarch_printable_names.
As a consequence, the list of selftest effectively executed depends on
the order the _initialize_* functions are called. This can be observed
with the following:
$ ./gdb/gdb \
-data-directory ./gdb/data-directory \
-quiet -batch -ex "maint selftest" 2>&1 \
| grep -E "Ran [0-9]+ unit tests"
Ran 145 unit tests, 0 failed
$ GDB_REVERSE_INIT_FUNCTIONS=1 ./gdb/gdb \
-data-directory ./gdb/data-directory \
-quiet -batch -ex "maint selftest" 2>&1 \
| grep -E "Ran [0-9]+ unit tests"
Ran 82 unit tests, 0 failed
To fix this, make register_test_foreach_arch register a lazy selftest
generator. This way when the test generator is eventually executed, all
architectures are registered and we do not have a dependency on the
order the initialize functions are executed in.
Tested on x86_64-linux
