1llvm-as - LLVM assembler2========================3 4.. program:: llvm-as5 6SYNOPSIS7--------8 9**llvm-as** [*options*] [*filename*]10 11DESCRIPTION12-----------13 14**llvm-as** is the LLVM assembler. It reads a file containing human-readable15LLVM assembly language, translates it to LLVM bitcode, and writes the result16into a file or to standard output.17 18If *filename* is omitted or is ``-``, then **llvm-as** reads its input from19standard input.20 21If an output file is not specified with the **-o** option, then22**llvm-as** sends its output to a file or standard output by following23these 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 the28 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 the31 output file has the same name as the input file, except that the ``.bc``32 suffix is appended.33 34OPTIONS35-------36 37**-f**38 Enable binary output on terminals. Normally, **llvm-as** will refuse to39 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 STATUS50-----------51 52If **llvm-as** succeeds, it will exit with 0. Otherwise, if an error occurs, it53will exit with a non-zero value.54 55SEE ALSO56--------57 58:manpage:`llvm-dis(1)`, as(1)59
