Description Jan-Benedict Glaw 2021-05-30 18:55:47 UTC 
Hi!

As I started automated testing again, I found an issue with the nds32 backend code. Host/build compiler is nearly master, GCC source tree is a8f588be038317bf1e9c71f7e626a3d23255ab37.

./gcc/configure --target=nds32le-linux --enable-werror-always --enable-languages=all --disable-gcov --disable-shared --disable-threads --without-headers --prefix=/var/lib/laminar/run/gcc-nds32le-linux/1/toolchain-install

make all-gcc
