| NAME |
| </h3> |
| |
| llvmg++ |
| |
| <h3> |
| SYNOPSIS |
| </h3> |
| |
| llvmg++ [options] filename |
| <h3> |
| DESCRIPTION |
| </h3> |
| |
| The llvmg++ command is the LLVM C++ front end. It is a modified version of g++ |
| that takes C++ programs and compiles them into LLVM bytecode or assembly |
| language, depending upon the options. |
| <p> |
| |
| The llvmg++ program uses the LLVM assembler gccas and the LLVM linker gccld to |
| do the work of creating complete programs. |
| <p> |
| |
| Being derived from the GNU Compiler Collection, llvmg++ 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. |
| <p> |
| |
| Below you will find several commonly used options: |
| |
| <h3> |
| OPTIONS |
| </h3> |
| |
| <ul> |
| <li> -S |
| <br> |
| Do not generate an LLVM bytecode file. Rather, compile the source file |
| into an LLVM assembly language file. |
| <p> |
| |
| <li> -c |
| <br> |
| Do not generate a linked executable. Rather, compile the source file into |
| an LLVM bytecode file. This bytecode file can then be linked with other |
| bytecode files later on to generate a full LLVM executable. |
| <p> |
| |
| <li> -o <i>filename</i> |
| <br> |
| Specify the output file to be <i>filename</i>. If <i>filename</i> is -, |
| then llvmgcc sends its output to standard output. |
| <p> |
| |
| <li> -I <i>directory</i> |
| <br> |
| Add a directory to the header file search path. This option can be |
| repeated. |
| <p> |
| |
| <li> -L <i>directory</i> |
| <br> |
| Add <i>directory</i> to the library search path. This option can be |
| repeated. |
| <p> |
| |
| <li> -l<i>name</i> |
| <br> |
| Link in the library lib<i>name</i>.[bc | a | so]. This library should be |
| a bytecode library. |
| <p> |
| |
| <li>-Wl,<i>option</i> |
| <br> |
| Pass <i>option</i> to the linker (usually gccld). |
| <p> |
| |
| </ul> |
| |
| <h3> |
| EXIT STATUS |
| </h3> |
| |
| If llvmg++ succeeds, it will exit with 0. Otherwise, if an error occurs, it |
| will exit with a non-zero value. |
