[PATCH 3/8] Disassembly unit test: disassemble one instruction

[Pedro Alves]

I'd much prefer if the core of the unit testing framework doesn't learn
about different random subsystems.  Consider what we'd do if we
wanted to reuse selftest.c in gdbserver.  I think we will at some point.

How about we move all this gdbarch stuff elsewhere, like
gdb/arch-utils.c or a new gdb/arch-selftests.c?

You'd then have,

- call the new function typedef "arch_self_test_function"

- in arch-selftests.c:

static std::vector<arch_self_test_function *> gdbarch_tests;

void
register_arch_self_test (arch_self_test_function *function)
{
  gdbarch_tests.push_back (function);
}

namespace selftests {

arch_tests ()
{
  for (const auto &f : gdbarch_tests)
    {
      const char **arches = gdbarch_printable_names ();
      int i;
   [...]
}

} /* namespace selftests */

void
_initialize_arch_selftests (void)
{
#if GDB_SELF_TEST
  register_self_test (selftests::arch_tests);
#endif
}

Thanks,
