Kevin Lim c23b23f4e7 Add in checker. Supports dynamically verifying the execution of instructions, as well as limited amount of control path verification. It will verify anything within the program, but anything external (traps, interrupts, XC) it assumes is redirected properly by the CPU. Similarly it assumes the results of store conditionals, uncached loads, and instructions marked as "unverifiable" are correct from the CPU.
base/traceflags.py:
build/SConstruct:
cpu/SConscript:
cpu/cpu_models.py:
    Add in Checker.
cpu/base.cc:
    Add in checker support.  Also XC status starts off as suspended.
cpu/base.hh:
    Add in checker.

# CpuModel class
#
# The CpuModel class encapsulates everything the ISA parser needs to
# know about a particular CPU model.
class CpuModel:
# Dict of available CPU model objects. Accessible as CpuModel.dict.
dict = {}
# Constructor. Automatically adds models to CpuModel.dict.
def __init__(self, name, filename, includes, strings):
self.name = name
self.filename = filename # filename for output exec code
self.includes = includes # include files needed in exec file
# The 'strings' dict holds all the per-CPU symbols we can
# substitute into templates etc.

# Define CPU models.
#
# Parameters are:
# - name of model
# - filename for generated ISA execution file
# - includes needed for generated ISA execution file
# - substitution strings for ISA description templates
