| 5 | SYNOPSIS |
| 6 | -------- |
| 7 | |
| 8 | |
| 9 | **llvm-link** [*options*] *filename ...* |
| 10 | |
| 11 | |
| 12 | DESCRIPTION |
| 13 | ----------- |
| 14 | |
| 15 | |
| 16 | **llvm-link** takes several LLVM bitcode files and links them together into a |
| 17 | single LLVM bitcode file. It writes the output file to standard output, unless |
| 18 | the **-o** option is used to specify a filename. |
| 19 | |
| 20 | **llvm-link** attempts to load the input files from the current directory. If |
| 21 | that 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 |
| 23 | one is searched for every input file if necessary. The directories are searched |
| 24 | in the order they were specified on the command line. |
| 25 | |
| 26 | |
| 27 | OPTIONS |
| 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. |
| 80 | |
| 81 | |
| 82 | |
| 83 | |
| 84 | EXIT STATUS |
| 85 | ----------- |
| 86 | |
| 87 | |
| 88 | If **llvm-link** succeeds, it will exit with 0. Otherwise, if an error |
| 89 | occurs, it will exit with a non-zero value. |
