LLVM: `llvm-link` tool

NAME

llvm-link

SYNOPSIS

llvm-link [options] <filename> [filename ...]

DESCRIPTION

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.

OPTIONS

-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.
-f
Overwrite output files. By default, llvm-link will not overwrite an output file if it alreadys exists.
-o <filename>
Output filename. If filename is -, then llvm-link will write its output to standard output.
-d
If specified, llvm-link prints a human-readable version of the output bytecode 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 bytecode 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.
