Chisel building riscv-gnu-toolchain for Sodor

I want to build 'riscv-gnu-toolchain' for Sodor Project available in :

ucb-bar/riscv-sodor

I failed to clone it as suggested by its readMe using :

 'git clone [email protected]:riscv/riscv-gnu-toolchain.git'

I also tried to use the latest version of the repository, and it generates the following warning :

 'configure: WARNING: unrecognized options: --disable-float, --with-xlen'

Which suggests that this is not the right version. I tried to use the version in ROCKET CHIP, but I failed also.

Which version of 'riscv-gnu-toolchain' I can use to compile Sodor's tests?

Thank you Chris. I found a version that work with Sodor. Here are the commands that can be used to checkout this version and build it:

git clone https://github.com/riscv/riscv-gnu-toolchain cd riscv-gnu-toolchain git submodule update --init --recursive git checkout 06c957ab mkdir build cd build ../configure --prefix=${INSTALL_LOC} --disable-float --disable-atomic --with-xlen=32 --with-arch=RV32I make

Sodor currently only supports the Privileged Spec v1.7, so you need to use an older version of riscv-gnu-toolchain. Older versions of the toolchain will recognize the options --disable-float and --with-xlen. It appears that there are no tags on riscv-gnu-toolchain, so you'll have to do some detective work to find the correct commit.
