PROFILE
Alireza Torabian
Worked on the swiftlang/llvm-project repository to enhance loop fusion capabilities within the LLVM compiler infrastructure. Focused on expanding legal fusion opportunities by enabling cross-loop dependence analysis across SameSD loops and incorporating forward-dependency handling. This involved extending the Dependence Analysis flow and updating fusion decision logic to safely recognize and exploit forward loop-carried dependencies, allowing for more aggressive fusion across complex loop nests. Utilized C++ and LLVM IR, applying skills in compiler optimization, static analysis, and scalar evolution. The work improved the compiler’s ability to identify parallelism, supporting more efficient code generation and optimization for high-performance computing scenarios.
