Summary of Changes
Hello @dearblue, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request undertakes a significant refactoring of the virtual machine's dispatch macros. The core objective is to eliminate code duplication and enhance the clarity and maintainability of the VM dispatch mechanism. By abstracting common operations such as operand decoding, code hook invocation, and task state checking into dedicated helper macros, the codebase becomes more streamlined and organized, benefiting both switch-based and computed goto dispatch implementations.
Highlights
- Macro Refactoring: Consolidated duplicate code within VM dispatch macros (INIT_DISPATCH, CASE, NEXT, END_DISPATCH) by extracting common logic into new helper macros, reducing redundancy across different dispatch modes.
- New Helper Macros: Introduced
DECODE_OPERANDS,CALL_CODE_HOOKS, andRETURN_IF_TASK_STOPPEDto encapsulate repetitive code segments, improving modularity and maintainability of the VM dispatch logic. - Improved Readability: Simplified the main dispatch macros by replacing inline duplicated code with calls to the new helper macros, making the dispatch logic clearer and easier to understand, especially with conditional compilation for task scheduling.
