4SYNOPSIS

7:program:`llvm-link` [*options*] *filename ...*

9DESCRIPTION
10-----------
11
12:program:`llvm-link` takes several LLVM bitcode files and links them together
13into a single LLVM bitcode file.  It writes the output file to standard output,
14unless the :option:`-o` option is used to specify a filename.
15
16:program:`llvm-link` attempts to load the input files from the current
17directory.  If that fails, it looks for each file in each of the directories
18specified by the :option:`-L` options on the command line.  The library search
19paths are global; each one is searched for every input file if necessary.  The
20directories are searched in the order they were specified on the command line.
21
22OPTIONS
23-------
24
25.. option:: -L directory
26
27 Add the specified ``directory`` to the library search path.  When looking for
28 libraries, :program:`llvm-link` will look in path name for libraries.  This
29 option can be specified multiple times; :program:`llvm-link` will search
30 inside these directories in the order in which they were specified on the
31 command line.
32
33.. option:: -f
34
35 Enable binary output on terminals.  Normally, :program:`llvm-link` will refuse
36 to write raw bitcode output if the output stream is a terminal. With this
37 option, :program:`llvm-link` will write raw bitcode regardless of the output
38 device.
39
40.. option:: -o filename
41
42 Specify the output file name.  If ``filename`` is "``-``", then
43 :program:`llvm-link` will write its output to standard output.
44
45.. option:: -S
46
47 Write output in LLVM intermediate language (instead of bitcode).
48
49.. option:: -d
50
51 If specified, :program:`llvm-link` prints a human-readable version of the output
52 bitcode file to standard error.
53
54.. option:: -help
55
56 Print a summary of command line options.
57
58.. option:: -v
59
60 Verbose mode.  Print information about what :program:`llvm-link` is doing.
61 This typically includes a message for each bitcode file linked in and for each
62 library found.
63
64EXIT STATUS
65-----------
66
67If :program:`llvm-link` succeeds, it will exit with 0.  Otherwise, if an error
68occurs, it will exit with a non-zero value.
