Hi Baoquan,

Sorry for the inconvenience, /root/0day/gcc-12.1.0-nolibc/sh4-linux/bin
/sh4-linux-gcc is for x86_64 machine, as the name "ampere-mtsnow-altra",
is it a arm server?

the tool for arm64 can be downloaded from 
https://cdn.kernel.org/pub/tools/crosstool/files/bin/arm64/12.1.0/

Best Regards,
Rong Chen
