.SH "NAME"
llvm\-link \- LLVM linker
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-link\fR [\fIoptions\fR] \fIfilename ...\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBllvm-link\fR takes several \s-1LLVM\s0 bitcode files and links them together into a
single \s-1LLVM\s0 bitcode file.  It writes the output file to standard output, unless
the \fB\-o\fR option is used to specify a filename.
.PP
\&\fBllvm-link\fR 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
\&\fB\-L\fR 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.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-L\fR \fIdirectory\fR" 4
.IX Item "-L directory"
Add the specified \fIdirectory\fR to the library search path.  When looking for
libraries, \fBllvm-link\fR will look in path name for libraries.  This option can be
specified multiple times; \fBllvm-link\fR will search inside these directories in
the order in which they were specified on the command line.
.IP "\fB\-f\fR" 4
.IX Item "-f"
Enable binary output on terminals.  Normally, \fBllvm-link\fR will refuse to
write raw bitcode output if the output stream is a terminal. With this option,
\&\fBllvm-link\fR will write raw bitcode regardless of the output device.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name.  If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-link\fR will
write its output to standard output.
.IP "\fB\-S\fR" 4
.IX Item "-S"
Write output in \s-1LLVM\s0 intermediate language (instead of bitcode).
.IP "\fB\-d\fR" 4
.IX Item "-d"
If specified, \fBllvm-link\fR prints a human-readable version of the output
bitcode file to standard error.
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print a summary of command line options.
.IP "\fB\-v\fR" 4
.IX Item "-v"
Verbose mode.  Print information about what \fBllvm-link\fR is doing.  This
typically includes a message for each bitcode file linked in and for each
library found.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBllvm-link\fR succeeds, it will exit with 0.  Otherwise, if an error
occurs, it will exit with a non-zero value.
