Re: different address spaces (was Re: internal compiler error at dwarf2out.c:8362)
Martin,
I think that the AVR people would very much appreciate if you would report
occasionally on your progresses concerning your realization of the different
address space issue on your personal HC05 port. (In my opionion, the lack for
support of different memory spaces is the key weakness of the present avr
port and I think that any avr-gcc user would be very happy if this weakness
could be removed some day.)
While I think, that I now have quite a clear picture on which kind of
modifications would be required for the back-end (namely more sophisticated
define_expand patterns and possibly some new unspecs (and corresponding
define_insn/define_split patterns) for EEPROM and PMEM ), I don't have any
idea on how complicated the work on the tree level would be and of course,
whether your approach generally would be suitable for being included in
mainline gcc.
Yours,
Björn
