NAME
     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 out-
	    put 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 out-
	    put 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.

     --override <filename>
	    Adds the passed-in file to the link and overrides symbols that  have
	    already  been  declared  with  the	definitions  in the file that is
	    passed in. This flag can be specified multiple times to have  multi-
	    ple files act as overrides. If a symbol is declared more than twice,
	    the definition from the file declared last takes precedence.

     --import <function:filename>
	    Specify  a	function that should be imported from the specified file
	    for linking with ThinLTO. This  option  can  be  specified	multiple
	    times to import multiple functions.

     --summary-index <filename>
	    Specify  the path to a file containing the module summary index with
	    the results of an earlier ThinLTO link. This option is required when
	    --import is used.

     --internalize
	    Internalize the linked symbols.

     --disable-debug-info-type-map
	    Disables the use of a uniquing type map for debug info.

     --only-needed
	    Link only needed symbols.

     --disable-lazy-loading
	    Disable lazy module loading.

     --suppress-warnings
	    Suppress all linker warnings.

     --preserve-bc-uselistorder
	    Preserve the use-list order when writing LLVM bitcode.

     --preserve-ll-uselistorder
	    Preserve the use-list order when writing LLVM assembly.

     --ignore-non-bitcode
	    Do not error out when a non-bitcode file is encountered  while  pro-
	    cessing an archive.

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