5 llvm-g++ - LLVM C++ front-end
9 B<llvm-g++> [I<options>] I<filename>
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.
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.
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.
31 Print a summary of command line options.
35 Do not generate an LLVM bitcode file. Rather, compile the source
36 file into an LLVM assembly language file.
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

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.
