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.
2020-06-13Made the source code cleaner.mrb0nk500
2020-06-01Did some more refactoring to the assembler.mrb0nk500
- Refactored the symbol, and fixup table to now use a linked list - Added support for local symbols to the assembler. - Rewrote SuBEditor, and SuBAsm to use local symbols.
2020-05-30Fixed a typo, oof.mrb0nk500
2020-05-30Refactored the assembler a bit more, in order to removemrb0nk500
code duplication. The assembler now uses pre-tokens, which are smaller tokens, that make up the larger tokens.
2020-05-29Make JSL, JSR absolute, and remove RTL.mrb0nk500
The reason for doing this was because JSL, and RTL are redundent, as they both do the same thing as JSR, and RTS.
2020-05-28Refactored the assembler, yet again, and implementedmrb0nk500
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.
2020-05-18Fixed some more bugs in the assembler.mrb0nk500
2020-05-18Did 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.
2020-05-09Added support for single quote marks to the emulator'smrb0nk500
assembler. Single quote marks works in the assembler just like they do in C, except that it only supports a handful of escaped characters, like '\n', and '\r'.
2020-04-27Added support for including source files to themrb0nk500
emulator's assembler. And removed three pointers, and the linewrap table from zero page, in SuBEditor. I moved the linewrap table to address $1000. And because of finally adding include support to the assembler, I can now start work on SuBAsm!
2020-04-17Made both the assembly language monitor, and themrb0nk500
emulator smaller, and faster. I am also starting to make SuBEditor's source code more readable.
2020-04-09Completely changed the assembler.mrb0nk500
It now has a lexer/tokenizer, along with a parser. I have also made the emulator even smaller.
