Worked on the jasmin-lang/jasmin repository to improve the correctness of vector instruction semantics within the compiler. Focused on a targeted bug fix in the VPCMPGT operation by updating the comparison logic in JWord.ec, replacing the <= operator with < to ensure accurate 'greater than' evaluation. This change addressed a subtle issue in vector compare paths, reducing the risk of incorrect outcomes in downstream code generation. Leveraged skills in compiler development and low-level programming, specifically using ECL, to deliver a precise, low-risk update that enhanced the reliability and predictability of vector operations for users relying on VPCMPGT semantics.
