Member Function Documentation
|
protected |
Loads the iproc table with instruction processing functors.
This normally happens from the constructor.
|
protected |
Load the cached register descriptors.
This happens at construction and on set_register_dictionary() calls.
|
protected |
Make sure memory is set up correctly.
For instance, byte order should be little endian.
|
inlinestatic |
Construct a prototypical dispatcher.
The only thing this dispatcher can be used for is to create another dispatcher with the virtual create method.

Access the register dictionary.
The register dictionary defines the set of registers over which the RISC operators may operate. This should be same registers (or superset thereof) whose values are stored in the machine state(s). This dictionary is used by the Dispatcher class to translate register names to register descriptors. For instance, to read from the "eax" register, the dispatcher will look up "eax" in its register dictionary and then pass that descriptor to the RiscOperators::readRegister operation. Register descriptors are also stored in instructions when the instruction is disassembled, so the dispatcher should probably be using the same registers as the disassembler, or a superset thereof.
The register dictionary should not be changed after a dispatcher is instantiated because the dispatcher's constructor may query the dictionary and cache the resultant register descriptors.
