this is very WIP.

zxq5 added 50 commits 2026-02-14 02:47:33 +00:00

started work on compiler 2582ad10fa

rust macros make me want to unalive. b33fdbfeec

started work on c compiler fd5b305576

Merge remote-tracking branch 'refs/remotes/origin/compiler' into compiler 091dabfbf3

started on codegen, scaffolding basically done b9f98bff7b

codegen progress 259746558f

updated gitignore 782c842a42

added a to-do list and bacon.toml for developing the compiler 63c9d858b4

fixed a bug with the multiply function in core.dsa and added a print_num e31deb594f

function to print.dsa for decimal numbers

compiler working for some mathematical expressions, function calls and 52ef7872f0

simple conditionals

added some documentation and started on compiler for custom language (not C) based on previous prototypes. pretty broken state rn. 8f7163c459

minor code changes for codegen 5573c5a609

- compiler works for basic maths expressions and functions 3afeafc9d4

- basic pointers and reading values from pointers works
- writing to pointers not yet implemented (looks painful so a problem
  for tomorrow)
- updated print library. the compiler has this hardcoded in all programs
  for now

updated roadmap with progress ce2eda72a0

- refactored lexer 7973b2afca

- updated lexer to allow hex and binary integer literals
- updated parser with support for writing to pointers
- updated code generation to support writing to pointers
- fixed a bug with codegen where args are loaded from incorrect offsets
  due to saving registers prior to calling.

updated dsc example to reflect current feature set. 48a74bfde2

updated assembler logging f25db6c8fd

added support for DSA libraries to compiler and made some optimisations. 14a04a524c

provided an API for the editor to use.

forgot to commit this f4933b55fb

added basic logging to common dd20401ad6

TODO: improve logging

wrote dsa/dsc code examples including an allocator 889ee8ef71

deleted old files and modified some dsa source files 7780f5804f

integrated compiler in DSA editor fa8aa1cd29

fixed bug where stack inspector shows incorrect addresses cb65a928c8

updated roadmap a1099249e9

deleted the c compiler 8d130a870c

updated compiler to support multiple frontends and backends a35cfbe864

updated docs 89762b54e3

reorganised code examples 2f91c4127c

added a (very incomplete) C frontend for DSAC c2bf9f6667

added a brainf&&k module to the compiler (specialised module so no b8abbfd02f

frontend/backend distinction or use of standard model)

modified editor to include syntax for .dsc files e69514e46e

started working on build system 1fcfb3120b

updated assembler to write to binary files correctly 🤦 bbcef7178f

fix broken build system commit 250b780e14

update roadmap and ISA spec e9329eca95

- C frontend broken for now 6699333b2c

- If statements work properly now (hopefully)
- still issues with while loops pushing vars to the stack. need scoping
  implemented to fix this!

- refactored registers.rs and fixed faulty logic.
- made register allocation optimisations

fixed pointers and stuff. 828f5bfb2d

block allocator implementation and example 9f35fc9415

updated compiler with support for more operators. 328741eb51

(only the unary operators from this are implemented for now)

renamed NoReg to Null in common f7ed764e96

- updated assembler to support new shift implementation e2be83414b

- updated emulator to support new shift implementation
- updated emulator to rename NoReg to Null as in the common lib

- implementation of <var> <op> = <expr> type statements such as `x += 22241a5633

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.)

docs update 509b3465f1

- renamed assembler_runner to just assembler 931af90789

- 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

used claude to write a language spec (syntax and simple examples) for 5e575e2cd8

DSC that we can follow as a reference for implementation.

broken commit, started working on scopes 8361833b1c

forgot to commit these 75ad04cf95

moved loc d66baf6f99

continued on register allocator rewrite, slow progress as scoping is 201b18069b

proving to be a challenge
