NAME

|
|
|
|
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.
