 2026-02-10 10:05:13 +00:00
zxq5 931af90789 - renamed assembler_runner to just assembler 
- implemented type parsing including custom types and generics (useless
  for now as we do no semantic analysis)
- implemented struct literal parsing
- implemented struct definition parsing (no generics yet)
- implemented tuple parsing
- registers are now allocated starting from zero
- updated to-dos

zxq5 509b3465f1 docs update 2026-02-09 00:10:49 +00:00
zxq5 22241a5633 - implementation of <var> <op> = <expr> type statements such as `x += 
5`
- implementation of logical and shift operations in parser and codegen.
- implementation of sizeof keyword as unary operator

in progress (non functional)
- implementation of prefix and postfix inc/dec operators

- array access by index (implemented, untested as arrays aren't
  implemented yet). essentially just a pointer write with offset.
- struct/member access (parsing implemented, untested.)

zxq5 98668c681e more optimisations test program ~54MIPS -> ~110MIPS 2025-06-29 02:04:14 +01:00
zxq5 05a25447b2 minor optimisation to reduce unnecessary allocations 2025-06-28 03:43:20 +01:00
zxq5 56d2abe17f - optimised main emulator loop, allowing updates only once every roughly 32,000 instructions. 
- optimised memory access patterns, removing unecessary mutability and accesses.
- replaced the standard HashMap with an implementation that uses a faster hashing algorithm.

results:

before:
    - our benchmark program with ~4m instructions would take around for their data to make it to the UI, and a bit over 200ms to actually run

after:
    - our benchmark program with ~4m instructions can run in around 75ms, and the UI receives the update almost instantly.

conclusion:
- emulator performance should be around 2-3x faster than before.
