LLVM IR Binding for Rust

This LLVM IR Binding provides intuitive and well-organized safe Rust API for analyzing existing LLVM modules. Thus the whole library is thread-safe. This crate does not provide the functionality to produce new LLVM module or change existing module.

How to use

use llir;

// Create context
let context = llir::Context::create();

// Specify path to the byte code
let path = Path::new("path/to/your/llvm/bytecode.bc");

// Load the module with that path
let module = context.load_module(path)?;

// Iterate through functions, blocks, and instructions...
for func in module.iter_functions() {
  for block in func.iter_blocks() {
    for instr in block.iter_instructions() {
      // Do things to instr...
    }
  }
}
