PROFILE

Nicholas Coughlin

Worked on the UQ-PAC/BASIL repository to enhance the GTIRB loader by adding support for unsigned division operations, specifically targeting the parsing and translation of unsigned bitwise arithmetic. The approach involved introducing a dedicated case for 'udiv_bits.0' and mapping it to the BVUDIV operation, thereby enabling accurate handling of unsigned division within the loader’s workflow. This update improved binary analysis accuracy and expanded operator coverage for downstream tooling. The work leveraged skills in compiler development and reverse engineering, utilizing Scala to implement the feature. The contribution focused on deepening the loader’s capabilities for unsigned arithmetic without addressing bug fixes.
