SYNOPSIS

llvm-as [options] &lt; filename&gt;
llvm-as [options] [filename]
<h3>
DESCRIPTION
</h3>
The llvm-as command is the LLVM assembler. It takes a human readable LLVM
assembly language file and translates it into LLVM bytecode.
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>
By default, llvm-as places its output into filename.bc.
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.

</ul>

DESCRIPTION
</h3>
The llvm-dis command is the LLVM disassembler. It takes an LLVM bytecode file
and converts it into one of several human readable formats.
and converts it into LLVM assembly language or C source code with equivalent
functionality.
<p>
If filename is omitted, llvm-dis reads its input from standard input.
<p>
The default output file for llvm-dis is determined by the following logic:
<ul>
<li>
If the input is standard input or the file -, then the output is standard
output.
<p>
<li>
If the input filename ends in .bc, then the output filename will be
identical, except that the .bc suffix will be replaced by the .ll or .c
suffix (for LLVM assembly language and C code, respectively).
<p>
<li>
If the input filename does not end in .bc, then the output filename will be
identical to the input filename, except that the .ll or .c suffix will be
appended to the filename (for LLVM assembly language and C code,
respectively).
</ul>
By default, llvm-dis places its output in filename.ll, removing the .bc suffix
if it exists.
