How to evaluate gcc13 for nuclei sdk

If you want to take a try with gcc13 for nuclei sdk, you need to download our prebuilt still in development gcc13/clang17 toolchain from https://drive.weixin.qq.com/s?k=ABcAKgdSAFcdQ1noOT, and use a develop branch of nuclei sdk https://github.com/Nuclei-Software/nuclei-sdk/tree/develop.

From 2023.10.9, now develop branch is changing to use gcc13, and merged all the changes from feature/llvm branch, please switch to use develop branch.

Latest qemu for this branch can be found here: https://drive.weixin.qq.com/s?k=ABcAKgdSAFcWD95meC

About how to use this toolchain, please click(In Chinese) https://doc.weixin.qq.com/doc/w3_ASUAMQZqALwUNtgZUvFTH2hR2F7KD?scode=ABcAKgdSAFc1u2vvWl

Download the toolchain, and export it to system PATH, and just try it.

If you want to try nuclei llvm toolchain, just pass TOOLCHAIN=nuclei_llvm when run make command.

If you want to test gnu toolchain support Zc and Xxlcz, you can try it like this:

nuclei llvm not yet support Zc

cd application/baremetal/benchmark/coremark
# default TOOLCHAIN is nuclei_gnu, no need to pass TOOLCHAIN=nuclei_gnu
## Test cpu arch rv32imafc, which means n300 with single float point, and C extension
make CORE=n300f ARCH_EXT=_zca_zcb_zcf_zcmp_zcmt clean
make CORE=n300f ARCH_EXT=_zca_zcb_zcf_zcmp_zcmt all

## Test cpu arch rv32imaf_zca_zcb_zcf_zcmp_zcmt, which means n300 with single float point, and Zc extension
make CORE=n300f ARCH_EXT=_zca_zcb_zcf_zcmp_zcmt clean
make CORE=n300f ARCH_EXT=_zca_zcb_zcf_zcmp_zcmt all

## Test cpu arch rv32imaf_zca_zcb_zcf_zcmp_zcmt_xxlcz, which means n300 with single float point, and Zc extension, and Xxlcz extension
make CORE=n300f ARCH_EXT=_zca_zcb_zcf_zcmp_zcmt_xxlcz clean
make CORE=n300f ARCH_EXT=_zca_zcb_zcf_zcmp_zcmt_xxlcz all
