NAME
       llvm-as - LLVM assembler

SYNOPSIS
       llvm-as [options] [filename]

DESCRIPTION
       llvm-as is the LLVM assembler.  It reads a file containing human-
       readable LLVM assembly language, translates it to LLVM bitcode, and
       writes the result into a file or to standard output.

       If filename is omitted or is "-", then llvm-as reads its input from
       standard input.

       If an output file is not specified with the -o option, then llvm-as
       sends its output to a file or standard output by following these rules:

       o   If the input is standard input, then the output is standard output.

       o   If the input is a file that ends with ".ll", then the output file
           is of the same name, except that the suffix is changed to ".bc".

       o   If the input is a file that does not end with the ".ll" suffix,
           then the output file has the same name as the input file, except
           that the ".bc" suffix is appended.

OPTIONS
       -f  Enable binary output on terminals.  Normally, llvm-as will refuse
           to write raw bitcode output if the output stream is a terminal.
           With this option, llvm-as will write raw bitcode regardless of the
           output device.

       -help
           Print a summary of command line options.

       -o filename
           Specify the output file name.  If filename is "-", then llvm-as
           sends its output to standard output.

EXIT STATUS
       If llvm-as succeeds, it will exit with 0.  Otherwise, if an error
       occurs, it will exit with a non-zero value.
