cisc-0.2/Makefile, branch new-instruction-handler

- Cleaned up a bit of the code.

2020-11-20T16:50:47Z

- Made the debug print for the CPU flags more readable. - Started work on implementing line number support into SuBAsm.

Refactored get_addr(), and all of the effective

2020-08-13T21:25:09Z

address handling. It's now all done using several functions for each addressing mode, with the result being the effective address. I did this to make the codebase cleaner, and more readable.

- Implemented a new opcode table.

2020-07-07T00:04:41Z

- 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.

Did some more stuff.

- 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. :)

Refactored the assembler, yet again, and implemented

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.

Put the instruction, and I/O routines into separate

functions. I did this to make it more readable, while still making it fast, due to inlining it.

Made both the assembly language monitor, and the

2020-04-18T02:07:14Z

emulator smaller, and faster. I am also starting to make SuBEditor's source code more readable.

Completely changed the assembler.

2020-04-09T06:06:50Z

It now has a lexer/tokenizer, along with a parser. I have also made the emulator even smaller.

Added support in SuBEditor for true backspace, and

2020-03-24T22:46:44Z

inserting characters without replacing the old ones.

Revamped the opcode table, made the emulator more

2020-03-17T19:36:07Z

efficient, and ported SuBEditor to C. I revamped the opcode table to add another prefix bit for the addressing mode, finally giving access to all addresses, without wasting any bytes. I made the stack based operations more efficient, by sort of applying Duff's device to it. And I ported SuBEditor to C, to make it easier for me to figure out how to implement SuBAsm.
