In general, the biggest gap in my knowledge relates to registers, how the ABI defines their use and how GDB likes to number them. Things that eventually need to be implemented: o KGDB * src/sys/powerpc/include/gdb_machdep.h * src/gnu/usr.bin/gdb/kgdb/trgt_powerpc.c o Threading: * src/lib/libthread_db/arch/powerpc/* -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
