advanced Published 8 Jun 2026
Action Steps
  1. Implement a parser combinator library in JavaScript to handle ARM32 instructions
  2. Use the library to parse ARM32 assembly code and generate an abstract syntax tree (AST)
  3. Write tests to validate the parser's correctness and robustness
  4. Integrate the parser with the existing emulator codebase
  5. Optimize the parser for performance and readability
