SYNOPSIS
llvm-g++ [options] filenameDESCRIPTION
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.
- -lname
- Link in the library libname.[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).
