Six and a half hours this time ... one new opcode, and all old opcodes
now in a deprecated format. Hooray, progress!
For building the table, I've decided to move from:
for(uint opcode : range(65536)) {
if(match(...)) bind(opNAME, ...);
}
To instead having separate for loops for each supported opcode. This
lets me specialize parts I want with templates.
And to this aim, I'm moving to replace all of the
(read,write)(size, ...) functions with (read,write)<Size>(...) functions.
This will amount to the ~70ish instructions being triplicated ot ~210ish
instructions; but I think this is really important.
When I was getting into flag calculations, a ton of conditionals
were needed to mask sizes to byte/word/long. There was also lots of
conditionals in all the memory access handlers.
The template code is ugly, but we eliminate a huge amount of branch
conditions this way.
