AQ Code

Updated BytecodeGenerator's processing logic for virtual machine operators such as IF, and updated the padding method for virtual machine operators.

Refactoring the parameter acquisition function simplifies the code and improves readability and maintainability.

Updated the logic for handling operators such as GOTO, IF, etc. for virtual machines. Removed obsolete test bytecode.

The runtime logic of virtual machine functions has been modified and may contain unknown errors.

Refactoring the parameter fetch function to simplify the code using decoding Uleb128 to improve readability and maintainability. Sample bytecode has not been changed yet.

The VM design contains partial errors, temporarily stopping compiler.cc development until the VM fixes the errors.

Updated README.md

Optimized constructors and assignment operators for Token structures to simplify code and ensure correct move semantics.

Add the delete function of LexMap class and the code of HandleFuncDecl function, and simplify the handling of function declaration in BytecodeGenerator.

Fixed warnings in compiler.cc. Fixed unused variable warnings in functions and renamed SetType method to SetSubType to improve code readability.
