FlasCC uses a version of LLVM-GCC 4.2 with a custom LLVM backend that generates ActionScript bytecode capable of running within the Flash Runtime. More specifically, the bytecode runs in the ActionScript virtual machine (AVM). This lets you compile arbitrary C/C++ code into a managed bytecode format capable of high performance execution within the Flash Runtime on Mac, Windows, or Linux
