Worked on the bytecodealliance/wasmtime repository to enhance AArch64 support by addressing non-PIC relocation handling in the cranelift-object component. Focused on preventing runtime panics by implementing Aarch64AdrPrelPgHi21 and Aarch64AddAbsLo12Nc relocations, enabling correct instruction pairing for colocated symbols in non-PIC mode. This involved fixing an unimplemented panic in process_reloc, directly improving build reliability and runtime stability for Wasmtime on AArch64 architectures. The work required deep understanding of system programming and backend development, leveraging Rust to ensure robust cross-architecture deployment. Contributed one targeted bug fix, demonstrating attention to edge cases and platform-specific reliability concerns.
