While the code is namespaced out properly, the files weren't separated
into their own directory. This moves the files so that introducing a general
interface is easier in the future for supporting other architectures.
Hides the opcode tables that the interpreter and JIT interface with to
execute instructions.
This does not, however, hide the read-only tables that the assembler and
disassembler use.
This is actually used as the DSP JIT, so this should be with the other JIT
source files.
This commit also makes it so changes to the JIT emitter don't require
recompiling all of the DSP core (i.e. changing the JIT won't require the
interpreter to be rebuilt).
Previously the two operand register selection bits were inverted, causing "CMPAR AC1, AX0.H" to be disassembled as "CMPAR AC0, AX1.H".
DSP RE is always fun: on the one hand Nintendo does a lot of stupid shit, so anything weird could be a legitimate bug of the UCode that is not supposed to make any sense. On the other hand, Dolphin *also* does a lot of stupid shit, so there's always that doubt.
Note: completely untested change - done with the GH text editor, just to show you how much I care :) . These operand descriptions are only used for disassembly, so no real behavior change is expected.
While further increasing the table width doesn't make the code any less
ugly, it makes it easy to generate auto-comments in the IDA processor
plugin. Also, use spaces for alignment instead of tabs.
