cisc-0.2 - An emulator for the Sux instruction set.

2020-08-08	Did a ton of stuff.	mrb0nk500
	- Changed the file structure of the SuB Suite, so that all variable declarations, symbols, and constants are in a single file. - Moved the C library functionss into a separate file, and made them use stack frames. - Added support for using the emulator's assembler for realtime debugging, to enter it, get in to stepping mode by pressing Ctrl+s, press any other key, then press F1, The reason for having to press some other key before pressing F1 is because it only allows entering the assembler when the keyboard is not ready. - Added the ".res" directive to the emulator's assembler, the ".res" directive tells the assembler to reserve however many bytes specified by the operand. - Fixed some bugs in the emulator's assembler.
2020-07-08	- Simplified some parts of the codebase.	mrb0nk500
	- Fixed some bugs with the push, and pull functions - Fixed a bug in the assembler.
2020-07-06	- Implemented a new opcode table.	mrb0nk500
	- Added a new preifx called the OF prefix, which adds the contents of a specific register to the current operand. - Added a table generator, which parses opcode table csv files.
2020-06-13	Optimized, and cleaned up the codebase.	mrb0nk500

2020-06-13	Renamed get_opsize(), to get_addrsize(), in order to	mrb0nk500
	make it clear about what it does.
2020-06-13	Make the registers single 64 bit uints, and convert	mrb0nk500
	all the value getting, and setting into macros. This is to make the codebase cleaner.
2020-06-11	Did some more stuff.	mrb0nk500
	- Fix some bugs with strings. - Started to refactor the instruction functions. - Added support for using RS prefixes on the memory based increment, and decrement instructions. - Started work on SuBAsm's lexer. Have fun looking at this, BieHDC. :)
2020-05-28	Refactored the assembler, yet again, and implemented	mrb0nk500
	support for comma separated values. The assembler now uses a linked list of tokenized lines, each containing a linked list of tokens for that line. I also moved all of the large tables into the higher parts of memory, in order to free up the lower part of memory for the user. Comma sepparated values only work with directives, and only with the byte", word, dword, and qword directives. I also added support for getting the upper, and lower halves of an address. The tokens for both of those are '<', and '>' respectively.
2020-05-18	Did alot of stuff while I was up at the family trailer.	mrb0nk500
	- Moved the large enums, and large tables into separate header files. - Added enums for implementing the base extension - Fixed a bug in the assembler. - Worked more on SuBAsm.
2020-05-06	Removed some duplicate code in the assembler, and made	mrb0nk500
	the processor status register, a union now.
2020-05-04	Made all address decoding, and memory reads/writes be	mrb0nk500
	done with a union, in order to make it more readable.
2020-05-03	Put the instruction, and I/O routines into separate	mrb0nk500
	functions. I did this to make it more readable, while still making it fast, due to inlining it.
