Thought about using a trick for handling long values on 32-bit systems as
splitting them up in register form, however that would be a bit ugly. What I
need is a way to have a growable buffer where I can still access it as a
buffer directly, rather than just say being an output stream. Well, I suppose
IntBuffer works, I can go back as needed, but if it ever needs resizing I will
have to reallocate and recopy the data. I will need an Assembler base class in
NARF that will be extended to by the DynaRec assembler, it can act on a base
buffer. Say for PowerPC the instructions are all 32-bit in length while on x86
they would not be so much like that. Sadly Buffer cannot be extended so I
cannot write a 24-bit integer or oddly sized buffers at all. I could always
just write my own extendable thing that uses a ByteBuffer, if the result gets
too large I can re-allocate them as needed.

I am going to need a key I can use in a map to specify an operation, although
I can just use the class of operands.

And using a MethodHandle should simplify things.

Had this idea that the base assembler could create the CodeBank that is used
for target of code execution.

Perhaps I can write my own simulated system of sorts so I can make sure the
logic of my operands is correct as desired. But that would duplicate effort
sort of. Perhaps instead of PowerPC I should target MIPS first instead since
that is far simpler. I have written a MIPS instruction simulator before, which
was quite easy.

However, MIPSr6 is a complete game changer as I will actually need two code
generators. One for r5 and older and one for r6 and newer since so much has
changed.
