The goal of DragonEgg is to make gcc-4.5 act like llvm-gcc without requiring any gcc modifications whatsoever. -DragonEgg is a shared library (llvm.so) that is loaded by gcc at runtime. It -uses the new gcc plugin architecture to disable the GCC optimizers and code -generators, and schedule the LLVM optimizers and code generators (or direct -output of LLVM IR) instead. Currently only Linux and Darwin are supported, -and only on x86-32 and x86-64. It should be easy to add additional unix-like -architectures and other processor families. Since gcc-4.5 has not yet been -released, neither has DragonEgg. -To build DragonEgg you will need to -check out the development versions of -gcc, llvm -and DragonEgg from their respective -subversion repositories. +DragonEgg is a shared library (llvm.so) +that is loaded by gcc at runtime.
