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  re-
     sult 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:

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

     * 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.

     * 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 suf-
       fix 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.
