llvm-link - LLVM linker
llvm-link [options] filename ...
The llvm-link command 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.
The llvm-link command 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.
-, then llvm-link will write its output to standard output.
If llvm-link succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.
