[Qemu-devel] dumping processor state after each instruction executed

[Vince Weaver <vince@csl.cornell.edu>]

Hello,

I was wondering if it is possible to insert some code into the translated
basic-block in order to dump the processor state to a file after every
single instcution?  This would be every single executed instruction,
(meaning it couldn't be just dump the state once at translation time).

I'm trying to use qemu as a frontend to the TAXI tool
  (http://www.eecs.umich.edu/~vlaovic/L150_vlaovic_s.pdf) while doing some
computer architecture work.

I've figured out how to add a helper function to the load/store routines
to get a memory trace file, but getting an instruction trace is proving to
be a bit harder.

Thanks for any help,
