Crate cargo_compiler_interrupts

cargo-compiler-interrupts provides you a seamless way to integrate the Compiler Interrupts to any Rust packages. Check out the Compiler Interrupts main repository for more info.

Requirements

• Rust 1.45.0 - 1.64.0 and LLVM 9 - 14 are required. Both must have the same LLVM version. Later LLVM versions are currently not supported due to the new LLVM pass manager.
• You can check the LLVM version from Rust and LLVM toolchains by running rustc -vV and llvm-config --version respectively.
• x86-64 architecture with Linux or macOS is highly recommended. Other architectures and platforms have not been tested and not guaranteed to work.

Installation

cargo-compiler-interrupts can be installed via cargo install.

cargo install cargo-compiler-interrupts

You can also fetch the repo and install using --path.

git clone https://github.com/bitslab/cargo-compiler-interrupts
cargo install --path ./cargo-compiler-interrupts

Getting started

cargo-compiler-interrupts provides three binaries:

cargo-lib-ci install    # install the CI library
cargo-build-ci          # build and integrate CI to the binary
cargo-run-ci            # run the CI-integrated binary

• cargo-lib-ci — manage the Compiler Interrupts library.
• cargo-build-ci — build and integrate the Compiler Interrupts to the package.
• cargo-run-ci — run the integrated binary. You can specify which binary to run by passing --bin <BINARY>.

Run cargo-lib-ci install to install the Compiler Interrupts library first. Before running cargo-build-ci, add the Compiler Interrupts API package as the dependency for your Cargo package and registers the Compiler Interrupts handler in your program. Compiler Interrupts API is provided through the compiler-interrupts package.

fn interrupt_handler(ic: i64) {
    println!("Compiler interrupt called with instruction count: {}", ic);
}

unsafe {
    compiler_interrupts::register(1000, 1000, interrupt_handler);
}

For more detailed usages and internals, run the command with --help option and check out the documentation.
