*              proctab.cpp                                              *
* Tables of processor instructions. The whole of this file is full of   *
* tables that I constructed some time ago. The main instruction tables  *
* include three arguments for instructions, which was necessary to      *
* easily include instructions like shld r/m16,r16,CL. I was maybe       *
* overexcessive with the number of slightly different modr/ms that I    *
* included but the tables have served well, and when you build them up  *
* from scratch instruction by instruction you do actually find a lot of *
* slightly different encodings, and the modrm encodings generally       *
* indicate what is actually being referenced (like a 16:32 pointer in   *
* memory, etc). I included the Z80 processor because I knew the Z80     *
* processor quite well, but mostly just to show it isnt hard to do.     *
* At one point I decided that I needed a uid for each instruction to    *
* enable proper reconstruction of the disassembly from a saved database *
* and so each instruction also has a uid for this purpose.              *
* Flags for modrm may seem excessive, but consider encodings like 0fae  *
* which includes the strange sfence instruction with no arguments and a *
* code of 0fae /7, along with stmxcsr m32 with the encoding 0fae /3     *
* Hence the flag FLAGS_MODRM indicates a modrm byte. Any argument       *
* encodings may indicate usage of that byte, but may not be present at  *
* all.                                                                  *
* Whilst I havent found any errors in here for some time it would need  *
* a very careful analysis to find any which may be present. Certainly   *
* newer instruction encodings (mmx, kni) may need more work, and it is  *
* worth looking at decodings which should not be possible (eg forced    *
* memory operands only may require looking at as some possible          *
* instructions are illegal)                                             *
