Worked on the rust-lang/gcc repository to enhance RISC-V architecture support in GCC, focusing on compiler development and embedded systems. Over two months, addressed a critical backend issue by ensuring the Zve32x extension correctly implies Zicsr, updating both configuration logic and test coverage to prevent misconfiguration in production builds. Additionally, implemented minimal support for the RISC-V double trap extension version 1.0, including new extension definitions, option mask updates, documentation, and tests. Used C and C++ to deliver these changes, improving code generation correctness and expanding GCC’s ability to target architectures with advanced trap handling mechanisms for embedded applications.

May 1, 2025In May 2025, rust-lang/gcc delivered minimal support for the RISC-V double trap extension (version 1.0), expanding GCC's target coverage to include the smdbltrp and ssdbltrp extensions. The work includes extension definitions, updates to option masks, documentation, and tests to ensure correct recognition and handling during compilation. This enables developers targeting architectures with double-trap trap mechanisms to compile and link code with GCC more reliably.

Apr 1, 2025Monthly work summary for 2025-04 focusing on RISC-V GCC maintenance and test updates. Delivered a critical fix ensuring Zve32x implies Zicsr in the common RISC-V configuration, and updated tests to reflect the dependency by using rv64im_zve32x instead of rv64gc_zve32x. This work improves backend stability, correctness of code generation for the Zve32x extension, and prevents misconfiguration in production builds. Commit included: a992164c2899735525a7a267654473b7e527ef0d.
