| 20 | SYNOPSIS |
| 21 | </h3> |
| 22 | |
| 23 | llvm-link [options] <filename> [filename ...] |
| 24 | <h3> |
| 25 | DESCRIPTION |
| 26 | </h3> |
| 27 | |
| John Criswell | 6243534 | 2003-09-26 16:32:00 +0000 | [diff] [blame] | 28 | The llvm-link command takes several LLVM bytecode files and links them together |
| 29 | into a single LLVM bytecode file. It writes the output file to standard |
| 30 | output, unless the -o option is used to specify a filename. |
| 31 | <p> |
| 32 | |
| 33 | The llvm-link command attempts to load the input files from the current |
| 34 | directory. If that fails, it attempts to locate each file within the |
| 35 | directories specified by the -L options on the command line. The library |
| 36 | search paths are global; each one is search for every input file if necessary. |
| 37 | The directories are searched in the order they were specified on the command |
| 38 | line. |

| John Criswell | 6243534 | 2003-09-26 16:32:00 +0000 | [diff] [blame] | 47 | Add the specified directory to the library search path. When looking for |
| 48 | libraries, llvm-link will look in pathname for libraries. This option can |
| 49 | be specified multiple times; llvm-link will search inside these directories |
| 50 | in the order in which they were specified on the command line. |

| 52 | |
| 53 | <li>-f |
| 54 | <br> |
| 55 | Overwrite output files. By default, llvm-link will not overwrite an |
| 56 | output file if it alreadys exists. |

| John Criswell | 6243534 | 2003-09-26 16:32:00 +0000 | [diff] [blame] | 61 | Output filename. If filename is -, then llvm-link will write its output to |
| 62 | standard output. |

| 66 | <br> |
| 67 | If specified, llvm-link prints a human readable version of the output |
| 68 | bytecode file to standard error. |
