- llvm-dis - LLVM disassembler
- opt - LLVM optimizer
- llc - LLVM static compiler
- lli - directly execute programs from LLVM bitcode
- llvm-link - LLVM bitcode linker
- llvm-ar - LLVM archiver
- llvm-nm - list LLVM bitcode and object file’s symbol table
- llvm-prof - print execution profile of LLVM program
- llvm-config - Print LLVM compilation options
- llvm-diff - LLVM structural ‘diff’
- llvm-cov - emit coverage information
- llvm-stress - generate random .ll files
- llvm-symbolizer - convert addresses into source code locations

## Debugging Tools

- bugpoint - automatic test case reduction tool
- llvm-extract - extract a function from an LLVM module
