llvm-dis - LLVM disassembler — LLVM 22.1.1 documentation

# llvm-dis - LLVM disassembler

## SYNOPSIS

llvm-dis [options] [filename]

## DESCRIPTION

The llvm-dis command is the LLVM disassembler. It takes an LLVM bitcode file and converts it into human-readable LLVM assembly language.

If filename is omitted or specified as `-`, llvm-dis reads its input from standard input.

If the input is being read from standard input, then llvm-dis will send its output to standard output by default. Otherwise, the output will be written to a file named after the input file, with a `.ll` suffix added (any existing `.bc` suffix will first be removed). You can override the choice of output file using the -o option.

## OPTIONS

-f

> Enable binary output on terminals. Normally, llvm-dis will refuse to write raw bitcode output if the output stream is a terminal. With this option, llvm-dis will write raw bitcode regardless of the output device.

-help

> Print a summary of command line options.

-o filename

> Specify the output file name. If filename is -, then the output is sent to standard output.

## EXIT STATUS

If llvm-dis succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.
