# llvm-link - LLVM bitcode linker

## SYNOPSIS

llvm-link [options] filename …

## DESCRIPTION

llvm-link takes several LLVM bitcode files and links them together into a single LLVM bitcode file. It writes the output file to standard output, unless the `-o` option is used to specify a filename.

## OPTIONS

`-f```

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

`-o` `filename`

  Specify the output file name. If `filename` is “`-`“, then llvm-link will write its output to standard output.

`-S```

  Write output in LLVM intermediate language (instead of bitcode).

`-d```

  If specified, llvm-link prints a human-readable version of the output bitcode file to standard error.

`-help```

  Print a summary of command line options.

`-v```

  Verbose mode. Print information about what llvm-link is doing. This typically includes a message for each bitcode file linked in and for each library found.

## EXIT STATUS

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