# 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.
        self.strings = strings

#
# 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
