Hi, all,
In this patch of nds32 port:
https://gcc.gnu.org/ml/gcc-patches/2015-01/msg00969.html
Since we remove the implementation of -mforce-fp-as-gp, -mforbid-fp-as-gp,
and -mex9 options, we need to update documentation as well.
The patch is attached and the plaintext ChangeLog is as follow.
gcc/ChangeLog
2015-01-14 Chung-Ju Wu <jasonwucj@gmail.com>
* doc/invoke.texi (NDS32 Options): Remove -mforce-fp-as-gp,
-mforbid-fp-as-gp, and -mex9 options.
Although these changes are target-specific part, I think it would be better
for others to have review comments, if any, on its format and layout.
If there is no other comments about this patch, I will commit it into
trunk after 24 hours.
Best regards,
jasonwucj

Can you cover these, and similar changes, in the release notes
at htdocs/gcc-5/changes.html, please? (Cf. gcc.gnu.org/about.html
for the web pages side of things.)

Thank for reminding me.
I am preparing such patch to describe nds32 port in the
release note of gcc5 changes.html, including the new options,
the options are removed, and ABI changes for variadic function:
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg00316.html
https://gcc.gnu.org/ml/gcc-patches/2015-01/msg00992.html
https://gcc.gnu.org/ml/gcc-patches/2015-01/msg00993.html
I will post that patch for web page soon. :)
Best regards,
jasonwucj
