I also hawe to ask if there are thoughts for introducing a flag with which it
will be possible to generate code that uses relative addressing for
intra-function calls (e.g. loops) but absolute addressing for out-of-function
branches (e.g. function calls).
The intent is to be able to move during runtime the image of a function to a
different memory location without any processing needed on the function image.
Currently this can only be achieved if out-ofsfunction relative references are
manually adjusted
