C Bootloader Experiment

Yeah I meant that it is 16bit code using 32bit registers and I´m looking for a way to get gcc to use 16bit registers.

Couldn't you just inline them, like: (From the GCC manual.)

Code: Select all

inline void foo (const char) __attribute__((always_inline));

I find a small macro like this very useful:

Code: Select all

#define INLINE_FUNCTION(_decl) \
    static inline _decl __attribute__((always_inline)); \
    _decl

Are you going to be running the code on a <= 286 processor?

[FlashBurn]

No, but I read that the "ret" instruction will also be 32bit, so that it tries to return to a 32bit address. I haven´t checked this. At the moment I try to get my old borland c++ 2.0 running and to compile for loader.
