It reads a file containing human readable LLVM assembly language, translates it to LLVM bytecode, and writes the result into a file or to standard output. <p> If filename is omitted or is -, then <tt>llvm-as</tt> reads its input from standard input. <p> If an output file is not specified with the <tt>-o</tt> option, then <tt>llvm-as</tt> sends its output to a file or standard output by the following logic: <ul> <li> If the input is standard input, then the output is standard output. <p> <li> 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. <p> <li> 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. <p> </ul> <h3>OPTIONS</h3> <ul> <li> -f <br> Force overwrite. Normally, <tt>llvm-as</tt> will refuse to overwrite an output file that already exists. With this option, <tt>llvm-as</tt> will overwrite the output file and replace it with new bytecode. <p> <li> -help <br> Print a summary of command line options. <p> <li> -o <filename> <br> Specify the output filename. If filename is -, then <tt>llvm-as</tt> sends its output to standard output. <p> <li> -stats <br> Print statistics. <p> <li> -time-passes <br> Record the amount of time needed for each pass and print it to standard error. <p> </ul> <h3>EXIT STATUS</h3> If <tt>llvm-as</tt> succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value. <h3>SEE ALSO</h3> <a href="llvm-dis.html"><tt>llvm-dis</tt></a> <a href="gccas.html"><tt>gccas</tt></a> <HR> Maintained by the <a href="http://llvm.cs.uiuc.edu">LLVM Team</a>. </body> </html>
