Hi, all, The nds32 target supports two features, fp-as-gp and ex9, designed for code size optimizations. They are majorly performed by linker so that compiler is merely to give some hints or directives with -mforce-fp-as-gp, -mforbid-fp-as-gp, and -mex9 options.
However, those two features are not available yet in the current nds32 port of GNU binutils package. For consistency concern, I think it would be better to remove them from gcc trunk as well for now. Committed as Rev. 219576: https://gcc.gnu.org/r219576 gcc/ChangeLog 2015-01-14 Chung-Ju Wu <jasonw...@gmail.com> * config/nds32/nds32.opt (mforce-fp-as-gp): Remove. (mforbid-fp-as-gp): Remove.
