* Store CpuRegister on a single byte
* Store operation sizes (0, 1, 2, 4) on a single byte
* Share the (disp) and (imm) fields of instruction arguments
* Store instructions as char[12] instead of std::string (>32B)
* Store instruction args in Argument[2], not std::vector (>24B)
Size changes:
CpuRegister: 4B -> 1B
Argument: 24B -> 8B
Instruction: >64B -> 32B
This reduced the malloc size from 3.3M to 177k after a standard 40-line
disassembly (this excludes OS files mapped to memory), and improved the
loading time for the SH3 instruction table by about 30% (100 ms -> 65
ms).
