Manipulate LLVM-IR in Pure Rust

Vicis

Manipulate LLVM IR in pure Rust (without LLVM).

Feel free to create issues and pull requests!

Requirements

• Vicis itself is not depending on llvm
  • However, I sometimes use llvm 13 for testing. (e.g. parsing the llvm-ir clang-13 emitted by vicis)

Examples

• Parse and dump *.ll file

cargo run --example parse FILE.ll

• Interpret *.ll file

cargo run --example interpreter FILE.ll # --release

• Iterate over instructions

• Compile LLVM IR into machine code

  • The example illustrates the way for x86_64, but it's easy to do the same thing for aarch64 (although aarch64 backend is still heavily under development.)
