then GDB isn't the place where you'd want to trade accuracy for a very
small speedup.
Yeah --- I'd be very concerned about GDB performance optimizations
that would cause GDB to not notice, say, corruptions of the stack by
buffer overruns.
If it's common for memory reads to be so expensive, you should buy a
better JTAG unit^W^W^W^W^W^W^W I'd rather we work on minimizing memory
accesses by unwinders than make assumptions which may not hold in
buggy programs.
Could you enable 'debug remote' while it's doing the unwinding, and
figure out what it's actually fetching?
