llvm-link — LLVM bitcode linker


llvm-link [options] filename ...


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.



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.


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


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


Print a summary of command line options.


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.
