.SH "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.
