The example C code uses far pointers, e.g., to set up interrupt vectors: typedef void @far (*interrupt_handler_t)(void); struct interrupt_vector { unsigned char interrupt_instruction; interrupt_handler_t interrupt_handler; }; So I do need support for 24-bit pointers in the Clang frontend, in order for the struct to fill four bytes here.

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
