SYNOPSIS

|

extract [options] [filename]

DESCRIPTION
|
|
</h3>
|
|
|
|
The extract 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, extract will
|
|
also remove unreachable global variables, prototypes, and unused types.
|
|
<p>
|
|
|
|
The extract command will read its input from standard input if filename is
|
|
omitted or if filename is -. The output is always written to standard output.
|
|
|
|
