<h3>NAME</h3>
|
|
<tt>llvmg++</tt>
|
|
|
|
<h3>SYNOPSIS</h3>
|
|
<tt>llvmg++ [options] filename</tt>
|
|
|
|
<h3>DESCRIPTION</h3>
|
|
|
|
The <tt>llvmg++</tt> command is the LLVM C++ front end. It is a modified
|
|
version of g++ that takes C++ programs and compiles them into LLVM bytecode or
|
|
assembly language, depending upon the options.
|
|
<p>
|
|
|
|
The <tt>llvmg++</tt> program uses the <tt>gccas</tt> and <tt>gccld</tt> to
|
|
assist with the creation of complete programs.
|
|
<p>
|
|
|
|
Being derived from the <a href="http://gcc.gnu.org">GNU Compiler Collection</a>,
|
|
<tt>llvmg++</tt> has many of g++'s features and accepts most of g++'s options.
|
|
It handles a number of g++'s extensions to the C++ programming language.
|
|
<p>
|
|
|
|
Below you will find several commonly used options:
|
|
|
|
<h3>
|
|
OPTIONS
|
|
</h3>
|
|
|
|
<ul>
|
|
<li> -S
|
|
<br>
|
|
Do not generate an LLVM bytecode file. Rather, compile the source file
|
|
into an LLVM assembly language file.
|
|
<p>
|
|
|
|
<li> -c
|
|
<br>
|
|
Do not generate a linked executable. Rather, compile the source file
|
|
into an LLVM bytecode file. This bytecode file can then be linked with
|
|
other bytecode files later on to generate a full LLVM executable.
|
|
<p>
|
|
|
|
<li> -o <i>filename</i>
|
|
<br>
|
|
Specify the output file to be <i>filename</i>.
|
|
<p>
|
|
|
|
<li> -I <i>directory</i>
|
|
<br>
|
|
Add a directory to the header file search path. This option can be
|
|
repeated.
|
|
<p>
|
|
|
|
<li> -L <i>directory</i>
|
|
<br>
|
|
Add <i>directory</i> to the library search path. This option can be
|
|
repeated.
|
|
<p>
|
|
|
|
<li> -l<i>name</i>
|
|
<br>
|
|
Link in the library lib<i>name</i>.[bc | a | so]. This library should
|
|
be a bytecode library.
|
|
<p>
|
|
|
|
<li>-Wl,<i>option</i>
|
|
<br>
|
|
Pass <i>option</i> to the linker (usually gccld).
|
|
<p>
|
|
|
|
</ul>
|
|
|

|
|
EXIT STATUS
|
|
