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.
