llvm-link - LLVM linker


llvm-link [options] filename ...


llvm-link takes several LLVM bytecode files and links them together into a single LLVM bytecode 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 pathname 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.

Overwrite output files. By default, llvm-link will not overwrite an output file if it alreadys exists.

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

If specified, llvm-link prints a human-readable version of the output bytecode 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 bytecode 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.
