January 2025 performance summary for VirisOnGithub/compilation. Delivered core enhancements to the CodeGenerator module, enabling more expressive and reliable generated code. Key features added include negation and bitwise opposite operations for bit-level manipulation with proper register handling, and support for variable declarations with register allocation and optional initialization expressions, including necessary imports and refactoring to accommodate variables. Business impact: Faster feature delivery for code-generation scenarios, reduced boilerplate, and lower risk of errors in generated code. Establishes a scalable foundation for future optimizations and language constructs in the code-generation backend. Technologies/skills demonstrated: code generator architecture, register allocation, bitwise operation support, import management, and module refactoring for variable support.
