Hi, all, In this patch of nds32 port: https://gcc.gnu.org/ml/gcc-patches/2017-11/msg01585.html
We add new options for NDS32 target. So we need to update documentation as well. The patch is attached and the plaintext ChangeLog is as follow: gcc/ChangeLog * doc/invoke.texi (NDS32 Options): Add -mext-perf, -mext-perf2 and -mext-string options. Committed as https://gcc.gnu.org/r256564 I will also cover these changes in the release notes at htdocs/gcc-8/changes.html with another wwwdoc patch soon. Best regards, jasonwucj
