A pure Go library for parsing, building, and manipulating LLVM IR without any C bindings or cgo. It provides an asm package for parsing LLVM IR assembly files and an ir package for constructing and operating on IR modules programmatically.

Use cases

• parse llvm ir assembly files in go
• generate llvm ir from a custom language compiler
• analyze and transform llvm ir modules
• build a compiler backend targeting llvm ir in pure go
• decompile llvm ir to go source
• inspect llvm bitcode-free ir without installing llvm

When to choose

• you need to work with LLVM IR in Go without compiling LLVM or using cgo
• you are writing a compiler frontend that emits LLVM IR
• you want to parse, analyze, or pretty-print .ll assembly files programmatically

When to avoid

• you need LLVM's optimization passes or code generation - this library only handles IR representation, not the LLVM toolchain
• you need to parse LLVM bitcode (.bc) binary files rather than textual IR
• you are not working in Go
