LLVM C++ front-end

## NAME

llvm-g++ - LLVM C++ front-end

## SYNOPSIS

**llvm-g++** \[*options*\] *filename*

## DESCRIPTION

The **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, **llvm-g++** compiles to native objects just like GCC does. If the **-emit-llvm** option is given then it will generate LLVM bitcode files instead. If **-S** (assembly) is also given, then it will generate LLVM assembly.

Being derived from the GNU Compiler Collection, **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.

## OPTIONS

- **--help**

  Print a summary of command line options.

- **-S**

  Do not generate an LLVM bitcode file.  Rather, compile the source file into an LLVM assembly language file.

- **-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.

- **-o** *filename*

  Specify the output file to be *filename*.

- **-I** *directory*

  Add a directory to the header file search path.  This option can be repeated.

- **-L** *directory*

  Add *directory* to the library search path.  This option can be repeated.

- **-l***name*

  Link in the library lib*name*.\[bc \| a \| so\].  This library should be a bitcode library.

- **-emit-llvm**

  Make the output be LLVM bitcode (or assembly) instead of native object (or assembly).

## EXIT STATUS

If **llvm-g++** succeeds, it will exit with 0.  Otherwise, if an error occurs, it will exit with a non-zero value.
