Hi,
In print_one_insn_test we have this cluster of skipped tests:
...
case bfd_arch_ia64:
case bfd_arch_mep:
case bfd_arch_mips:
case bfd_arch_tic6x:
case bfd_arch_xtensa:
return;
...
Enable some of these, and document in more detail why they're enabled or
skipped.
Likewise, document bfd_arch_or1k because it's an odd case.
Tested on x86_64-linux.
Any comments?
Thanks,
- Tom
