Hey,
So I'm looking over my setups again at what we do and do not have build testing and run-time testing, and I see that for nds32 I just cannot find a good toolchain. If I try for example https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/7.3.0/x... 64-gcc-7.3.0-nolibc-nds32-elf.tar.xz it first fails on the -G0 flag that we have set in and then it complains about a lack of position independent code support. Is the kernel.org toolchain perhaps configured incorrectly?
Hi Tom
You may try the following paths:

Oddly, his 6.4.0 gets farther along than his 7.3.0 ones, but still doesn't work as I get things like this: AS arch/nds32/cpu/n1213/start.o arch/nds32/cpu/n1213/start.S: Assembler messages: arch/nds32/cpu/n1213/start.S:256: Error: Incorrect syntax, sethi $ta,hi20(_start@GOTOFF). arch/nds32/cpu/n1213/start.S:256: Error: Incorrect syntax, ori $ta,$ta,lo12(_start@GOTOFF). arch/nds32/cpu/n1213/start.S:256: Warning: relax hint unrecognized instruction: line 254.
and it just keeps going from there. You may want to drop him an email about how he's configuring for nds32le. Last time I talked with him, he wasn't planning to re-spin the 7.3.x ones, but he might do gcc-8 once it's ready.
Related, is there a QEMU target for nds32 that we could leverage so that once the toolchain issue is resolved we can update .travis.yml to run tests on it? Thanks!
I am applying the QEMU offering permit. If it is ok. I will prepare it for you.
Thanks!
