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