Hi, XYZ is your actual architecture? Are you trolling? Alec

Hi I'm doing a port of Clang/LLVM - purely for the educational value - to the MC6809 (and HD6309 as a dub target) processors. I'll also want to eventually provide direct support for the AM9511 floating-point coprocessor as an option. I'm working with bleeding-edge code from the Git mirror. I've made some pretty decent progress; I copied the llvm/lib/Targets/MSP430 Target to
