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.
llvm-link attempts to load the input files from the current directory. If that fails, it looks for each file in each of the directories specified by the -L options on the command line. The library search paths are global; each one is searched for every input file if necessary. The directories are searched in the order they were specified on the command line.
-L directory
Add the specified directory to the library search path. When looking for libraries, llvm-link will look in path name for libraries. This option can be specified multiple times; llvm-link will search inside these directories in the order in which they were specified on the command line.
-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.
If llvm-link succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.
