12DESCRIPTION
13-----------
14
15
16**llvm-link** takes several LLVM bitcode files and links them together into a
17single LLVM bitcode file.  It writes the output file to standard output, unless
18the **-o** option is used to specify a filename.
19
20**llvm-link** attempts to load the input files from the current directory.  If
21that fails, it looks for each file in each of the directories specified by the
22**-L** options on the command line.  The library search paths are global; each
23one is searched for every input file if necessary.  The directories are searched
24in the order they were specified on the command line.

27OPTIONS
28-------
29
30
31
32**-L** *directory*
33
34 Add the specified *directory* to the library search path.  When looking for
35 libraries, **llvm-link** will look in path name for libraries.  This option can be
36 specified multiple times; **llvm-link** will search inside these directories in
37 the order in which they were specified on the command line.
38
39
40
41**-f**
42
43 Enable binary output on terminals.  Normally, **llvm-link** will refuse to
44 write raw bitcode output if the output stream is a terminal. With this option,
45 **llvm-link** will write raw bitcode regardless of the output device.
46
47
48
49**-o** *filename*
50
51 Specify the output file name.  If *filename* is ``-``, then **llvm-link** will
52 write its output to standard output.
53
54
55
56**-S**
57
58 Write output in LLVM intermediate language (instead of bitcode).
59
60
61
62**-d**
63
64 If specified, **llvm-link** prints a human-readable version of the output
65 bitcode file to standard error.
66
67
68
69**-help**
70
71 Print a summary of command line options.
72
73
74
75**-v**
76
77 Verbose mode.  Print information about what **llvm-link** is doing.  This
78 typically includes a message for each bitcode file linked in and for each
79 library found.

84EXIT STATUS
85-----------
86
87
88If **llvm-link** succeeds, it will exit with 0.  Otherwise, if an error
89occurs, it will exit with a non-zero value.
