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

Age	Commit message (Collapse)	Author
2023-10-22	Added opcode OP_DUP_*	Aryadev Chavali
	Duplicates the nth datum off the stack, pushing it to the top. Useful for operations such as MOV which eat the stack.
2023-10-22	Cleaned up inst.c	Aryadev Chavali
	Use (H)WORD_SIZE more, added some notes, etc
2023-10-22	Functions which convert (h)words to and from bytes	Aryadev Chavali
	Uses memcpy internally, so we don't need to care about endianness.
2023-10-22	Changed format of inst_print	Aryadev Chavali
	Prints the opcode then any operands in the following brackets
2023-10-21	Implemented opcode_as_cstr for NOT,OR,AND,XOR,EQ	Aryadev Chavali

2023-10-21	Helper functions for read/write instructions from darr or FILE*	Aryadev Chavali

2023-10-21	Switched from floats to halfword	Aryadev Chavali
	Registers are now just words, with pushing from and moving to registers with specified subtypes just pushing those types into the word registers. That means there are 8 word registers which can act as 16 half word registers, which themselves can act as 64 byte registers.
2023-10-16	Added opcode_as_cstr, opcode_type_as_cstr and inst_print	Aryadev Chavali
	Pretty self explanatory, helps with logging.
2023-10-16	Fixed bug with get_opcode_data_type	Aryadev Chavali
	Pushed the bits one step too far.
2023-10-16	Set opcode after reading parameters in inst_read_byte	Aryadev Chavali

2023-10-16	Added functionality to read and write instruction bytecode	Aryadev Chavali
	Uses some bit hacks to quickly check what data type an opcode may have by shifting down to units then casting it to a data_type_t. Not very well tested yet, we'll need to see now.
