...to distinguish between near and far pointers? LLVM doesn't support distinguishing between near and far pointers. Depending on how much work you want to put in and what exactly you're trying to build, you might be able to get away with just pretending all pointers are near and implementing __builtin_stm8_far_loadn() and __builtin_stm8_far_storen() intrinsics, though. > Anyway, I've put together enough skeleton code to successfully > compile, but on Mac OS X v10.5 ppc host this is what I get: > > $ Debug+Asserts/bin/clang -ccc-host-triple stm8-unknown-elf ../hello.c > -S -o ../hello.s >...

Hi there, Inspired by the recent FOSDEM keynote, I've tried to write an LLVM backend for the STM8 microcontroller platform. The STM8S-Discovery evaluation board [1] has been handed out for free or is sold dirt- cheap, but there is no Open Source cross-compiler for it. The available ST assembler, linker and USB flash programmer are closed- source Windows binaries. And the compiler
