glm94 bca2ad67f1 Fixed a bug with single parameter instructions that land at the end of a file expecting a comma. 2022-10-08 22:02:51 -05:00
glm94 fd44e03b1b Updated the Parser to try and give 'AddressParameter's more meaning depending on the SymbolType. 2022-10-08 18:21:11 -05:00
glm94 48a77950be Updated the way string symbols are handled, allowing the programmer to terminate a string with any byte or none at all. 2022-10-08 16:35:05 -05:00
glm94 8b6edc39be Updated the Parser to handle the variable declaration directive. 2022-10-08 16:15:10 -05:00
glm94 c142d2c6d0 Cleaned up the Symbol struct and updated code accordingly. 2022-10-08 14:43:00 -05:00
glm94 4b08707e67 Cleaned up the list implementation so as to NOT copy items into a new buffer. 2022-10-07 20:46:55 +00:00
glm94 bdb4d2b241 Updated the way Instructions keep track of symbols. Only their name is important but we need the Symbols to be able to track which Instruction they point to (if they do that is, i.e. a label symbol). 2022-10-06 21:11:22 -05:00
glm94 d53833c25f Added some debug print out for the instruction list and a helper function to get a string for any Registers enum. 2022-10-06 21:05:57 +00:00
glm94 f38da9cc74 A bit of cleanup. 2022-10-04 21:05:15 +00:00
glm94 33309a2759 Updated the Instruction's structure and updated the Parser accordingly. 2022-10-04 20:37:47 +00:00
glm94 1f7989533b Fixed a bug in the SymbolsTable where it wouldn't update its size. 2022-10-03 20:11:04 -05:00
glm94 cd1258a724 Fixed various Parser bugs. 2022-10-03 19:58:44 -05:00
glm94 be91e3c112 Updated the parser to better handle parameters, sort of and including a string length assembly program to use as a test for the whole assembler. 2022-10-03 21:26:28 +00:00
glm94 706f480e31 The Scanner will now check for empty lines (is the previous token and the current token a new line?) and simply not emit a NewLine Token. 2022-10-03 19:40:00 +00:00
glm94 a949007c75 Updated the ISA so the program will correctly see things like 'load', 'inc' and 'dec'. 2022-10-03 16:56:39 +00:00
glm94 a0d5d62a34 Fixed a bug in the Scanner when parsing a hex number, still not super robust but it'll work. 2022-10-03 15:20:31 +00:00
glm94 f7cd87f13f Started reworking the Parser to simplify how instructions will be represented. It will act like a 'first pass' that will do grammar checks but not verify the parameters of the opcodes. 2022-10-02 22:54:18 -05:00
glm94 55f4c32764 Missed this for the Scanner fix. 2022-10-02 22:12:16 -05:00
glm94 097eca383b Fixed a bug with the Scanner adding a blank line via a single NewLine Token when a file starts with a block of comments. 2022-10-01 20:43:55 -05:00
glm94 984683bfc5 Minor adjustment to Figure 1.1 2022-09-29 22:57:12 -05:00
glm94 0f42ad2997 Updated the ISA and added links in the table of contents. 2022-09-29 22:11:19 -05:00
glm94 63438b551b Got the scanner running again. Seems to be picking up punctuation, labels, identifiers and strings as expected. 2022-09-29 21:32:08 -05:00
glm94 e94e486e18 More refinements to the loading data instructions. I am truly bad at this whole thing... 2022-09-29 20:42:37 +00:00
glm94 2b71ac05a0 Added a note about a proposal regarding assembly language design. 2022-09-27 17:46:50 +00:00
glm94 02cf72902e Updated the load instructions. 2022-09-26 22:13:48 -05:00
glm94 afa84076c8 Added a command to make generating an opcode table a one liner. Updated the ISA. 2022-09-23 19:36:27 +00:00
glm94 925f7703d6 Updated the ISA, hopefully I can get this all put together in a thought out way. 2022-09-22 20:49:20 +00:00
glm94 a82a4c23ad Updated the docs. 2022-09-21 21:44:38 -05:00
glm94 f5c82d1c36 Added a LaTex document to put in writing how the machine should behave. 2022-09-21 16:23:11 +00:00
glm94 0b58e0124f Some refactoring to update everything to use the new structures and some new considerations for how Symbols and Instructions shoudl be represented. 2022-09-15 22:14:38 -05:00
glm94 2ae60a607c Incomplete, but I want to make sure the ideas I have here don't get wiped. Sadly this commit won't compile. 2022-09-15 21:29:27 +00:00
glm94 6d17dffcdf Added a SymbolTable object (untested at the moment) and redefined the Symbol object. I think when a Symbol is made only the size of it should matter to the code that will assemble the final binary. 2022-09-08 20:56:02 +00:00
glm94 2518214585 Added a length attribute to the symbol. 2022-09-06 14:15:45 +00:00
glm94 7004fff659 This feels like a trainwreck but eh. Changed the way the opcodes are managed. Hopefully this is the right direction when I add support for multiple ASM files. 2022-09-01 18:46:59 +00:00
glm94 13f8ff194b Smoothbrain indeed... 2022-08-30 22:48:49 -05:00
glm94 dac01ffd0c Changed the TokenClass from opcode to nomic, a less smoothbrain name IMO and also frees up Opcode for a better use later on. 2022-08-30 22:06:50 -05:00
glm94 3c7056c5e6 The main function will now write out the output of the parser. 2022-08-29 21:23:02 +00:00
glm94 6c7b8d5356 Fixed a bug where CMP REG, REG wouldn't get encoded and a disassembler bug related to said CMP bug. 2022-08-29 19:29:34 +00:00
glm94 5f437b6869 Both the assembler and the disassembler should now support all the instructions I've layed out thus far. 2022-08-29 18:51:48 +00:00
glm94 e3b4293314 Fixed a bug in the parser where the size of the binary was too big. 2022-08-29 18:02:11 +00:00
glm94 ae1e73e00f Fixed a bug to correct the location of symbols in the heap. 2022-08-29 16:00:02 +00:00
glm94 7385a807a5 Created a basic binary format to help guide the disassembler. 2022-08-29 15:57:14 +00:00
glm94 0d3f8a460e Added more instructions for the parser to emit and refactored the code in doing so. 2022-08-28 15:37:56 -05:00
glm94 c2111e2b88 Added support for the ADD and SUB opcodes to the disassembler. 2022-08-28 13:08:18 -05:00
glm94 8e9d1aefe8 Fixed some disassembler issues. At least some instuctions are being disassembled correctly. 2022-08-26 21:43:03 -05:00
glm94 0785f21805 Added a disassembler which is still very buggy. Also fixed some bugs with the opcode mask getting function. 2022-08-26 21:41:02 +00:00
glm94 e4a191a17e Refined the encoding some more. 2022-08-26 19:00:37 +00:00
glm94 eb5e2c506e Got the start of encoding opcodes. 2022-08-26 18:27:41 +00:00
glm94 0d060248cb Forgot about the bloody IN instruction... 2022-08-25 21:01:35 -05:00
glm94 80bea6f1a8 I'm dumb, fixed the CMP opcode overlap.. 2022-08-25 20:57:33 -05:00
