ffe40c4c20 Mark VR4300 exception handlers as cold. 2014-11-09 18:41:09 -05:00

e89f054674 Optimize extremely aggressively. 
Tell GCC to optimize cold functions for size and stash them away in
a separate part of the binary. Put the simulate core, meanwhile, on
the hot path. Also, bump optimization to -O3 as we can now "afford"
to do so.

e16a997119 Squash the longstanding memory bug. 
Forgot to mask the data by the dqm before writing it on the bus.
We should do this before putting the data on the bus to prevent
the extra operation in each consumer.
