DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.

For the bindings it would be quite a mess to not have the binding factory not be able to handle stuff for method descriptors. I need an available set which is used to show which registers are available for each pool and such.

13:58

I will have to fixup some of the PowerPC generation code for this new binding stuff. I can keep slots to their fixed size of 32-bits for example and have a dynamically growing stack location set.

This new standard binding code will at least unify various architectures and reduce duplicate code when they need to refer to registers and stack locations. On another note, I could add types to field information in the information decoder and then have MutableOpCode show that specific information. This way I can have stuff such as register selections and memory addresses. So then if the architecture definition contains registers again I can add extra information to the information decoder to include that information in fields. As previously stated this would make MutableOpCode printing much easier and could allow for setting of values based on register contents. I could then adapat the StandardBindings to use these real registers also. To be smart and type safe I would need to have the type of value to be placed be a bit more dynamic since some architectures might specify a specific range or set of bit for registers.

I can also include special alias groups and such, a mnemonic of sort for specific fields in instructions. So for PowerPC's mfspr, I can instead use for example "lr" instead of giving an integral amount.

I should split the builder for instruction information off to a separated class so it does not clutter the pimary info class.
