ovm - ARCHIVED - A stack based virtual machine to act as a target for other programming languages

Age	Commit message (Collapse)	Author
2023-11-03	Added a start address (equivalent to `main`) to assembler	Aryadev Chavali
	Creates a jump address to the label delegated by "global" so program starts at that point.
2023-11-02	Implemented CALL(_STACK) and RET on the assembler	Aryadev Chavali

2023-11-02	Made separate tokens for JUMP_ABS and JUMP_STACK	Aryadev Chavali
	Makes more sense, don't need to fiddle around with strings as much in the parser due to this!
2023-11-02	Started work on preprocessing jump addresses	Aryadev Chavali

2023-11-01	Implemented MALLOC_STACK and SUB in the assembler	Aryadev Chavali

2023-11-01	Implemented stack versions of MGET and MSET in assembler	Aryadev Chavali

2023-11-01	Implemented OP_MSIZE into lexer/parser of ASM	Aryadev Chavali

2023-11-01	Implemented lexer and parser for new memory management instructions	Aryadev Chavali

2023-11-01	Add MULT to lexer and parser for assembler	Aryadev Chavali

2023-11-01	Lexer now returns more descriptive tokens	Aryadev Chavali
	More useful tokens, in particular for each opcode possible. This makes parsing a simpler task to reason as now we're just checking against an enum rather than doing a string check in linear time. It makes more sense to do this at the tokeniser as the local data from the buffer will be in the cache most likely as the buffer is contiguously allocated. While it will always be slow to do linear time checks on strings, when doing it at the parser we're having to check strings that may be allocated in a variety of different places. This means caching becomes a harder task, but with this approach we're less likely to have cache misses as long as the buffer stays there.
2023-10-31	Lexer now returns errors on failure	Aryadev Chavali
	Currently only for invalid character literals, but still a possible problem.
2023-10-28	Introduced a column and line for each token	Aryadev Chavali
	Accurate error reporting can be introduced using this.
2023-10-26	Lexer forces uppercase for symbols	Aryadev Chavali

2023-10-26	Auto fill licenses	Aryadev Chavali

2023-10-26	Unified literal for numbers, main program now tokenises	Aryadev Chavali

2023-10-25	Separated lexer from main file in asm	Aryadev Chavali
