Running rust LLVM IR in the graalVM Raw graalAndRust.md You need to first install GraalVM, and then set your PATH so that you get the GraalVM binaries Then you need the rust tool chain installed, easiest way to do it is with rustup Create a simple program with rust eg: $ > cargo new --bin --vcs git graalRust However, it's more common to interact with cargo than with rustc directly. The output is generated in the test.s file, which is the assembly code. Cargo subcommand to easily use LLVM source-based code coverage. For development or debugging, you may want LLVM text-format (*.ll) files in $ cargo rustc--release-- --emit=llvm-bc This command calls cargo rustc, a cargo subcommand designed to pass arguments directly to rustc during a cargo build. What can be a compilation unit depends on what you are compiling to. Now run it with graal's llvm's IR interpreter, and don't forget to add rust's stdlib. fargo cargo rustc -- ++ --emit=llvm-ir will get cargo to cause rustc to emil llvm ir files. [PATCH v7 00/25] Rust support For rustc to generate LLVM IR, you need to pass the --emit=llvm-ir flag. You can pass this option to rustc in one of two ways: common Code that is useful in various codegen modules. There is cargo rustc to pass arbitrary compiler flags through Cargo to rustc. Rustc internally first compiles each .rs file to a HIR unit, then each HIR unit to a MIR unit, then combines the MIR units to compile a whole-program LLVM-IR unit. rustc - The Cargo Book - GitHub Pages How to get assembly output from building with Cargo? 1.
