You can use Qemu to generate traces for Dinero, patches for that were
previously mentioned in this thread.
Stalling is meaningless though... Qemu is not cycle-accurate.
If you really want cycle accurate values, you're going to have to feed the
traces from Qemu into a timing simulator. It might be possible to create
a simple mips timing simulator that hooks into Qemu (see my wddd 2008
paper) but that would involve significant hacking that's not really
related to Qemu development.
