I thought I should give the brand new architecture a try. Unfortunately,
that was not very successful.

Build reference: v4.17-rc1
gcc version: nds32le-elf-gcc (GCC) 7.3.0

Building nds32:defconfig ... failed

Am I missing something ?

Hi, Guenter:

This built failure is because the toolchain version you used is not
supported the latest intrinsic function/macro.
We are sending the latest patchset now and we expect the whole new
features will be supported in gcc8.0.0 and binutil2.31+.

If you'd like to get these new features of toolchain, you may use the
github version.
This is the built-script repo. https://github.com/andestech/build_script.git

Hmm. How comes that the defines are not there ? Also, is nds32_intrinsic.h 
supposed to be auto-generated ?

Answering my own question. This file is part of gcc. Presumably, the missing 
are declared in that file ?
Interesting, I always thought that the Linux kernel is supposed not to include 
include files, to avoid issues such as license poisoning. One lives and learns.


The toolchain as provided isn't usable for me since it is not position 

Arnd, it might make sense to drop the nds32 toolchain from kernel.org; its 
presence is at best misleading.
