DESCRIPTION
|
|
</h3>
|
|
|
|
The <tt>extract</tt> command takes the name of a function and extracts it from
|
|
the specified LLVM bytecode file. It is primarily used as a debugging tool to
|
|
reduce test cases from larger programs that are triggering a bug.
|
|
<p>
|
|
|
|
In addition to extracting the bytecode of the specified function,
|
|
<tt>extract</tt> will also remove unreachable global variables, prototypes, and
|
|
unused types.
|
|
<p>
|
|
|
|
The <tt>extract</tt> command reads its input from standard input if filename is
|
|
omitted or if filename is -. The output is always written to standard output.
|
|
