-=head1 NAME
-
-llvm-extract - extract a function from an LLVM module
-
-=head1 SYNOPSIS
-
-B<llvm-extract> [I<options>] B<--func> I<function-name> [I<filename>]
-
-=head1 DESCRIPTION
-
-The B<llvm-extract> command takes the name of a function and extracts it from
-the specified LLVM bitcode file. It is primarily used as a debugging tool to
-reduce test cases from larger programs that are triggering a bug.
-
-In addition to extracting the bitcode of the specified function,
-B<llvm-extract> will also remove unreachable global variables, prototypes, and
-unused types.
-
-The B<llvm-extract> command reads its input from standard input if filename is
-omitted or if filename is -. The output is always written to standard output,
-unless the B<-o> option is specified (see below).
-
-=head1 OPTIONS
-
-=over
-
-=item B<-f>
-
-Enable binary output on terminals. Normally, B<llvm-extract> will refuse to
-write raw bitcode output if the output stream is a terminal. With this option,
-B<llvm-extract> will write raw bitcode regardless of the output device.
-
-=item B<--func> I<function-name>
-
-Extract the function named I<function-name> from the LLVM bitcode. May be
-specified multiple times to extract multiple functions at once.
-
-=item B<--rfunc> I<function-regular-expr>
-
-Extract the function(s) matching I<function-regular-expr> from the LLVM bitcode.
-All functions matching the regular expression will be extracted. May be
-specified multiple times.
-
-=item B<--glob> I<global-name>
-
-Extract the global variable named I<global-name> from the LLVM bitcode. May be
-specified multiple times to extract multiple global variables at once.
-
-=item B<--rglob> I<glob-regular-expr>
-
-Extract the global variable(s) matching I<global-regular-expr> from the LLVM
-bitcode. All global variables matching the regular expression will be extracted.
-May be specified multiple times.
-
-=item B<-help>
-
-Print a summary of command line options.
-
-=item B<-o> I<filename>
-
-Specify the output filename. If filename is "-" (the default), then
-B<llvm-extract> sends its output to standard output.
-
-=item B<-S>
-
-Write output in LLVM intermediate language (instead of bitcode).
-

-
-=head1 EXIT STATUS
-
-If B<llvm-extract> succeeds, it will exit with 0. Otherwise, if an error
-occurs, it will exit with a non-zero value.
