2023-10-31Added new macro for bitwise comparison constructionAryadev Chavali
This pushes a datum of the same type as the operands, which is why it cannot use the comparator macro as that always pushes bytes.
2023-10-31Added flag which forces the printing of hexesAryadev Chavali
Anything other than char (which can just use print.byte to print the hex) and byte (which prints hexes anyway), all other types may be forced to print a hex rather than a number if PRINT_HEX is 1.
2023-10-31Use macros to stop duplication of codeAryadev Chavali
I've made a single macro which defines a function through some common metric, removing code duplication. Not particularly readable per se, but using a macro expansion in your IDE allows one to inspect the code.
2023-10-31Introduced 3 new union members to data_tAryadev Chavali
These new members are just signed versions of the previous members. This makes type punning and usage for signed versions easier than before (no need for memcpy).
2023-10-31Remove duplicated codeAryadev Chavali
2023-10-31Implemented all the comparatorsAryadev Chavali
So much reused code, I definitely need to find a way to make this cleaner.
2023-10-31Use standardised signed version of word type from base.hAryadev Chavali
2023-10-31Moved inst module to libAryadev Chavali
As it has no dependencies on vm specifically, and it's more necessary for any vendors who wish to target the virtual machine, it makes more sense for inst to be a lib module rather than a vm module.
2023-10-31Implemented new types of EQ, forced all comparators to push bytesAryadev Chavali
Just need to call their unsigned versions. All comparators should push bytes as it makes return types uniform.
2023-10-31vm_execute_all: Print every cycle on VERBOSE >= 2, just print final state ↵Aryadev Chavali
otherwise Changed VERBOSE checks to ensure a degree of information.
2023-10-31Created routines for new comparator opcodes (not implemented)Aryadev Chavali
Will cause error if used currently, which is fine.
2023-10-31Introduced new instructions for comparisonAryadev Chavali
Comparing signed and unsigned versions of numbers. Same for EQ as well. Notice the irregular pattern of BYTE, CHAR, INT, HWORD,LONG,WORD as OPCODE_IS_TYPE requires the subcodes to be surrounded by BYTE and WORD.
2023-10-29Added a "usage" message and colours for assemblerAryadev Chavali
Prints useful and pretty messages when verbose being at least 1.
2023-10-29Fixed bug where JUMP_REGISTER couldn't be in bytecode readAryadev Chavali
2023-10-29Fixed bug where reading operand bytecode may stop prematurelyAryadev Chavali
This is due to checking for equality instead of just greater than in darr->used against darr->available.
2023-10-26Fixed bug where printing hword of an instruction prints number not hexAryadev Chavali
This is an easy fix.
2023-10-26Moved base functions from inst.c to dedicated fileAryadev Chavali
Doesn't make sense for them to be in the VM module when they have a more general purpose now.
2023-10-26vm/main takes a filename as input to execute bytecodeAryadev Chavali
Also prints a usage for incorrect usage.
2023-10-23Make root directory an include path, set #include's properlyAryadev Chavali
Easier to write includes now just using < with the module name, in comparison to using relative paths.
2023-10-23Added lib folder for general stuff, introduced as target to MakefileAryadev Chavali
2023-10-23Implemented simple example of a for loop in mainAryadev Chavali
2023-10-23src->vm, Makefile is now a bit more abstracted and pretty coloursAryadev Chavali
Changed folder names for sake of clarity (will be introducing a new build target soon), and Makefile can now easily support more targets.
