| 5 | SYNOPSIS |
| 6 | -------- |
| 7 | |
| 8 | |
| 9 | **llvm-as** [*options*] [*filename*] |
| 10 | |
| 11 | |
| 12 | DESCRIPTION |
| 13 | ----------- |
| 14 | |
| 15 | |
| 16 | **llvm-as** is the LLVM assembler. It reads a file containing human-readable |
| 17 | LLVM assembly language, translates it to LLVM bitcode, and writes the result |
| 18 | into a file or to standard output. |
| 19 | |
| 20 | If *filename* is omitted or is ``-``, then **llvm-as** reads its input from |
| 21 | standard input. |
| 22 | |
| 23 | If an output file is not specified with the **-o** option, then |
| 24 | **llvm-as** sends its output to a file or standard output by following |
| 25 | these rules: |
| 26 | |
| 27 | |
| 28 | \* |
| 29 | |
| 30 | If the input is standard input, then the output is standard output. |
| 31 | |
| 32 | |
| 33 | |
| 34 | \* |
| 35 | |
| 36 | If the input is a file that ends with ``.ll``, then the output file is of |
| 37 | the same name, except that the suffix is changed to ``.bc``. |
| 38 | |
| 39 | |
| 40 | |
| 41 | \* |
| 42 | |
| 43 | If the input is a file that does not end with the ``.ll`` suffix, then the |
| 44 | output file has the same name as the input file, except that the ``.bc`` |
| 45 | suffix is appended. |
| 46 | |

| 49 | |
| 50 | OPTIONS |
| 51 | ------- |
| 52 | |
| 53 | |
| 54 | |
| 55 | **-f** |
| 56 | |
| 57 | Enable binary output on terminals. Normally, **llvm-as** will refuse to |
| 58 | write raw bitcode output if the output stream is a terminal. With this option, |
| 59 | **llvm-as** will write raw bitcode regardless of the output device. |
| 60 | |
| 61 | |
| 62 | |
| 63 | **-help** |
| 64 | |
| 65 | Print a summary of command line options. |
| 66 | |
| 67 | |
| 68 | |
| 69 | **-o** *filename* |
| 70 | |
| 71 | Specify the output file name. If *filename* is ``-``, then **llvm-as** |
| 72 | sends its output to standard output. |
| 73 | |
| 74 | |
| 75 | |
| 76 | |
| 77 | EXIT STATUS |
| 78 | ----------- |
| 79 | |
| 80 | |
| 81 | If **llvm-as** succeeds, it will exit with 0. Otherwise, if an error |
| 82 | occurs, it will exit with a non-zero value. |
