11DESCRIPTION
12-----------
13
14**llvm-as** is the LLVM assembler.  It reads a file containing human-readable
15LLVM assembly language, translates it to LLVM bitcode, and writes the result
16into a file or to standard output.
17
18If *filename* is omitted or is ``-``, then **llvm-as** reads its input from
19standard input.
20
21If an output file is not specified with the **-o** option, then
22**llvm-as** sends its output to a file or standard output by following
23these rules:
24
25* If the input is standard input, then the output is standard output.
26
27* If the input is a file that ends with ``.ll``, then the output file is of the
28  same name, except that the suffix is changed to ``.bc``.
29
30* If the input is a file that does not end with the ``.ll`` suffix, then the
31  output file has the same name as the input file, except that the ``.bc``
32  suffix is appended.
33
34OPTIONS
35-------
36
37**-f**
38 Enable binary output on terminals.  Normally, **llvm-as** will refuse to
39 write raw bitcode output if the output stream is a terminal. With this option,
40 **llvm-as** will write raw bitcode regardless of the output device.
41
42**-help**
43 Print a summary of command line options.
44
45**-o** *filename*
46 Specify the output file name.  If *filename* is ``-``, then **llvm-as**
47 sends its output to standard output.
48
49EXIT STATUS
50-----------
51
52If **llvm-as** succeeds, it will exit with 0.  Otherwise, if an error occurs, it
53will exit with a non-zero value.
