Pin1Yin1-rustc

Pin1Yin1Yu3Yan2's compiler written in rust.

Backends

There are two code generation backends: llvm and c. By default, both are enabled. You can disable all of them by using the --no-default-features flag.

e.g. enable c backend only

cargo build --release --no-default-features --features=backend-c

LLVM Backend

The version of llvm is llvm@18, by default, it's preferred to dynamic link to the system's llvm library.

If you want to use a different version of llvm, or you want to statically link to the llvm library, you can order the feature flags of inkwell

cargo build --release --no-default-features --features=backend-llvm,inkwell/llvm18-0-force-static

Enable the feature flag backend-llvm to not enough to compile, you must also enable one of the inkwell feature flags.

C Backend

C backend is just a code printer, it doesn't need any extra dependencies.

Feature flags

• default: Enable all features follow, and inkwell/llvm18-0-prefer-dynamic.
• backend-llvm: Enable llvm backend.
• backend-c: Enable c backend.
• parallel-declare: Enable parallel type declaration of items(like functions).

Note

• In archlinux, llvm is installed in /opt/llvm and only dynamic library is provided. If you want to compile and use llvm backend, you must set the LD_LIBRARY_PATH to /opt/llvm/lib.
