This function has a lengthy comment about Harvard-architecture address mapping and its side effects. It then calls gdbarch_integer_to_address(), from there avr_integer_to_address(), which eventually calls avr_make_saddr(). This functions adds AVR_SMEM_START to everything except 0. Something in that sequence is not quite right ;-), but I can't decide what. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
