Hi, Joseph,

Sorry for the late revised patch.
We have completed all of it based on your review comments.

Thanks for the comments.
We added GPLv3+exception in nds32_intrinsic.h header.

Thanks for the suggestion.
In the config.gcc, we used tm_defines for default endianness
so that we can define proper MULTILIB_DEFAULTS setting in nds32.h.
Now we can have only one t-mlibs used.


A revised patch is provided and here is a summary:

  1. Add GPLv3+exception copyright and license notice in nds32_intrinsic.h.
  2. Using only one t-mlibs is enough.
  3. Remove nds32-isa-v2.h, nds32-isa-v3.h, and nds32-isa-v3m.h.
  4. Add nds32-opts.h included by nds32.opt.
