=head1 NAME
llvm-g++ - LLVM C++ front-end
=head1 SYNOPSIS
B<llvm-g++> [I<options>] I<filename>
=head1 DESCRIPTION
The B<llvm-g++> command is the LLVM C++ front end. It is a modified
version of g++ that compiles C++/ObjC++ programs into native code,
LLVM bitcode or assembly language, depending upon the options.
By default, B<llvm-g++> compiles to native objects just like GCC does. If the
B<-emit-llvm> option is given then it will generate LLVM bitcode files instead.
If B<-S> (assembly) is also given, then it will generate LLVM assembly.
Being derived from the GNU Compiler Collection, B<llvm-g++> 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.
=head1 OPTIONS
=over
=item B<--help>
Print a summary of command line options.
=item B<-S>
Do not generate an LLVM bitcode file. Rather, compile the source
file into an LLVM assembly language file.
=item B<-c>
Do not generate a linked executable. Rather, compile the source
file into an LLVM bitcode file. This bitcode file can then be
linked with other bitcode files later on to generate a full LLVM
executable.
=item B<-o> I<filename>
Specify the output file to be I<filename>.
=item B<-I> I<directory>
Add a directory to the header file search path. This option can be
repeated.
=item B<-L> I<directory>
Add I<directory> to the library search path. This option can be
repeated.
=item B<-l>I<name>
Link in the library libI<name>.[bc | a | so]. This library should
be a bitcode library.
=item B<-emit-llvm>
Make the output be LLVM bitcode (or assembly) instead of native object (or
assembly).
=back
=head1 EXIT STATUS
If B<llvm-g++> succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
