=head1 NAME
llvm-link - LLVM linker
=head1 SYNOPSIS
B<llvm-link> [I<options>] I<filename ...>
=head1 DESCRIPTION
B<llvm-link> takes several LLVM bitcode files and links them together into a
single LLVM bitcode file. It writes the output file to standard output, unless
the B<-o> option is used to specify a filename.
B<llvm-link> attempts to load the input files from the current directory. If
that fails, it looks for each file in each of the directories specified by the
B<-L> options on the command line. The library search paths are global; each
one is searched for every input file if necessary. The directories are searched
in the order they were specified on the command line.
=head1 OPTIONS
=over
=item B<-L> F<directory>
Add the specified F<directory> to the library search path. When looking for
libraries, B<llvm-link> will look in path name for libraries. This option can be
specified multiple times; B<llvm-link> will search inside these directories in
the order in which they were specified on the command line.
=item B<-f>
Enable binary output on terminals. Normally, B<llvm-link> will refuse to
write raw bitcode output if the output stream is a terminal. With this option,
B<llvm-link> will write raw bitcode regardless of the output device.
=item B<-o> F<filename>
Specify the output file name. If F<filename> is C<->, then B<llvm-link> will
write its output to standard output.
=item B<-S>
Write output in LLVM intermediate language (instead of bitcode).
=item B<-d>
If specified, B<llvm-link> prints a human-readable version of the output
bitcode file to standard error.
=item B<-help>
Print a summary of command line options.
=item B<-v>
Verbose mode. Print information about what B<llvm-link> is doing. This
typically includes a message for each bitcode file linked in and for each
library found.
=back
=head1 EXIT STATUS
If B<llvm-link> succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
