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:

       • 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 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.
