The builder generates C and quake invokes the C compiler. Just like for gcc: the builder generates .mc and quake invokes m3cgc1. I will want much the same for LLVM. The builder will generate LLVM IR binaries and the LLVM tools will do the rest (invoked from quake). This makes it relatively easy to do cross builds from quake.<div><div>
