According to its documentation, exc_unwind on IRIX 6.5 currently uses .debug_frame information for unwinding purposes (and its native assembler now does not produce PDR sections there). I am not familiar with the set of all MIPS platforms, so I am moved to ask whether it would (1) be a good idea if or (2) be unnecessary for GDB to do the same thing. Paul
