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. 24 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. 75 76 =head1 SEE ALSO 77 78 L<llvm-gcc|llvmgcc> 79 80 =head1 AUTHORS 81 82 Maintained by the LLVM Team (L<http://llvm.org/>). 83 84 =cut 85 86
