# opt
> Runs optimizations and analyse LLVM source files.
> More information: <https://llvm.org/docs/CommandGuide/opt.html>.
- Run an optimization or analysis on a bitcode file:
`opt -{{passname}} {{path/to/file.bc}} -S -o {{file_opt.bc}}`
- Output the Control Flow Graph of a function to a `.dot` file:
`opt {{-dot-cfg}} -S {{path/to/file.bc}} -disable-output`
- Optimize the program at level 2 and output the result to another file:
`opt -O2 {{path/to/file.bc}} -S -o {{path/to/output_file.bc}}`
