This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Note: this README is for users rather than contributors. If you wish to contribute to the compiler, you should read CONTRIBUTING.md instead.

MOS target depends on llvm-mos and llvm-mos-sdk. Installation of llvm-mos is described in project's README, but it needs to be slightly modified:
git clone https://github.com/llvm-mos/llvm-mos
cd llvm-mos
# For MacOS, use `-DLIBXML2_LIBRARY=/usr/local/opt/libxml2/lib/libxml2.dylib` instead of `-DLIBXML2_LIBRARY=/usr/lib/x86_64-linux-gnu/libxml2.so`
cmake -C clang/cmake/caches/MOS.cmake -G "Ninja" -S llvm -B build \
-DLLVM_INSTALL_TOOLCHAIN_ONLY=OFF \
-DLLVM_BUILD_LLVM_DYLIB=ON -DLLVM_LINK_LLVM_DYLIB=ON \
-DLLVM_INSTALL_UTILS=ON -DLLVM_BUILD_UTILS=ON -DLLVM_TOOLCHAIN_UTILITIES=FileCheck \
-DLLVM_TOOLCHAIN_TOOLS="llvm-addr2line;llvm-ar;llvm-cxxfilt;llvm-dwarfdump;llvm-mc;llvm-nm;llvm-objcopy;llvm-objdump;llvm-ranlib;llvm-readelf;llvm-readobj;llvm-size;llvm-strings;llvm-strip;llvm-symbolizer;llvm-config;llc" \
-DLIBXML2_LIBRARY=/usr/lib/x86_64-linux-gnu/libxml2.so \
-DLLVM_TARGETS_TO_BUILD="MOS;X86" \
-DLLVM_ENABLE_PROJECTS="clang;lld;lldb"
cmake --build build -t install
Build & install llvm-mos-sdk:
git clone https://github.com/llvm-mos/llvm-mos-sdk
cd llvm-mos-sdk
cmake -G "Ninja" -B build
cmake --build build -t install
And finally build rust mos toolchain:
export RUST_TARGET_PATH=/usr/local/rust-mos-targets/
cp config.toml.example config.toml
# in config.toml adjust path to llvm-config
# if llvm-mos is installed to other than /usr/local prefix
./x.py build -i --stage 0 src/tools/cargo
./x.py build -i && (
ln -s ../../stage0-tools-bin/cargo build/x86_64-unknown-linux-gnu/stage1/bin/cargo
rustup toolchain link mos build/x86_64-unknown-linux-gnu/stage1
rustup default mos
mkdir -p $RUST_TARGET_PATH
python3 create_mos_targets.py $RUST_TARGET_PATH
)
