Over three months, contributed to lfortran/lfortran by building end-to-end support for BOZ literals to real number conversions, integrating this feature from frontend parsing through AST transformation to backend serialization and comprehensive testing. Addressed compiler correctness by fixing type conversion issues in semantic analysis, particularly for BOZ literal assignments and DATA statement validation, ensuring accurate handling of real variables and arrays. Expanded and refined the test suite to cover array initializers, implied DO loops, and type compatibility, improving reliability for downstream optimizations. The work leveraged C++, Fortran, and advanced compiler development skills, with a strong emphasis on static and semantic analysis.
