[GSoC] Rust Drop trait support in gccrs - Status Report 3

Janet Chien, a Google Summer of Code student, provides her third status report on implementing Rust’s Drop trait functionality in gccrs. Notable progress includes merging patches for Drop infrastructure refactoring and test cases for nested scopes, while other patches for function-scope drops, explicit returns, and non-unit tail expressions are currently under review. Future work involves refining existing patches and exploring a try/finally-based cleanup mechanism using the GCC Go frontend’s defer implementation.
