<h3>
NAME
</h3>
llvm-as
<h3>
SYNOPSIS
</h3>
llvm-as [options] [filename]
<h3>
DESCRIPTION
</h3>
The llvm-as command is the LLVM assembler. 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 llvm-as reads its input from standard
input.
<p>
If an output file is not specified with the -o option, then llvm-as 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, llvm-as will refuse to overwrite an output
file that already exists. With this option, llvm-as 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 llvm-as 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 llvm-as succeeds, it will exit with 0. Otherwise, if an error occurs, it
will exit with a non-zero value.
