      4 
      5 llvm-g++ - LLVM C++ front-end
      6 
      7 =head1 SYNOPSIS
      8 
      9 B<llvm-g++> [I<options>] I<filename>
     10 
     11 =head1 DESCRIPTION
     12 
     13 The B<llvm-g++> command is the LLVM C++ front end.  It is a modified
     14 version of g++ that compiles C++/ObjC++ programs into native code, 
     15 LLVM bitcode or assembly language, depending upon the options.
     16 
     17 By default, B<llvm-g++> compiles to native objects just like GCC does. If the
     18 B<-emit-llvm> option is given then it will generate LLVM bitcode files instead.
     19 If B<-S> (assembly) is also given, then it will generate LLVM assembly. 
     20 
     21 Being derived from the GNU Compiler Collection, B<llvm-g++> has many
     22 of g++'s features and accepts most of g++'s options.  It handles a
     23 number of g++'s extensions to the C++ programming language.

     25 =head1 OPTIONS
     26 
     27 =over
     28 
     29 =item B<--help>
     30 
     31 Print a summary of command line options.
     32 
     33 =item B<-S>
     34 
     35 Do not generate an LLVM bitcode file.  Rather, compile the source
     36 file into an LLVM assembly language file.
     37 
     38 =item B<-c>
     39 
     40 Do not generate a linked executable.  Rather, compile the source
     41 file into an LLVM bitcode file.  This bitcode file can then be
     42 linked with other bitcode files later on to generate a full LLVM
     43 executable.
     44 
     45 =item B<-o> I<filename>
     46 
     47 Specify the output file to be I<filename>.
     48 
     49 =item B<-I> I<directory>
     50 
     51 Add a directory to the header file search path.  This option can be
     52 repeated.
     53 
     54 =item B<-L> I<directory>
     55 
     56 Add I<directory> to the library search path.  This option can be
     57 repeated.
     58 
     59 =item B<-l>I<name>
     60 
     61 Link in the library libI<name>.[bc | a | so].  This library should
     62 be a bitcode library.
     63 
     64 =item B<-emit-llvm>
     65 
     66 Make the output be LLVM bitcode (or assembly) instead of native object (or
     67 assembly).
     68 
     69 =back
     70 
     71 =head1 EXIT STATUS
     72 
     73 If B<llvm-g++> succeeds, it will exit with 0.  Otherwise, if an error
     74 occurs, it will exit with a non-zero value.
