through the following phases.
1) Construct all param contexts
2) Call the checkParams() on each context
3) Build the configuration hierarchy
4) Construct all SimObjects
5) Initialize all SimObjects by calling init() on each one
6) Unserialize the checkpoint
7) Register all statisitcs
8) Check validity of all statistics (after that, no new stats)
9) Reset all stats.
10) Call SimStartup() which calls startup() on all SimObjects,
ParamContexts, and any other object deriving from StartupCallback
SConscript:
no more SimInit() we have SimStartup() now
sim/param.hh:

beacuse x <= y should be the same as x < y || x == y. (This wasn't
the case before.)

cpu/beta_cpu/alpha_params.hh:
Make AlphaSimpleParams inherit from the BaseFullCPU so that it doesn't

Updated behavior for non-speculative instructions (stores, any
other non-spec instructions): once they reach the head of the ROB,
the ROB signals back to the IQ that it can go ahead and issue the
non-speculative instruction. The instruction itself is updated so that
commit won't try to commit it again until it is done executing.

non-speculative instructions as well, which are issued only when
commit signals backwards that a nonspeculative instruction is at
the head of the ROB.
cpu/beta_cpu/inst_queue_impl.hh:
Updated to allow for non-speculative instructions to be in the inst
