Jeff Hi Jeff & Andrew, After a brief discussion with the previous maintainers of the Linux nds32 port, it is reasonable to deprecate nds32-linux for GCC 14 and remove it for GCC 15. However, considering that there are still customers relying on nds32le-elf and nds32be-elf for their embedded systems, it would be great to keep nds32le-elf and nds32be-elf in the GCC/binutils-gdb/newlib-cygwin repository.

Jeff Hi Jeff, As for gdbsim/openocd, I remember that we did have nds32 contributions previously: - gdb: http://sourceware.org/ml/gdb-patches/2013-07/msg00223.html - openocd: http://openocd.zylin.com/1259 I suppose they have recently been dropped from the current gdb/openocd repository due to the lack of maintenance. I will reach out to Andes members to inquire whether the architecture is still considered to be available in gdb/openocd. Regards, jasonwucj
