PROFILE

Mingzhu Yan

Over a three-month period, this developer enhanced RISC-V support across multiple repositories, focusing on both feature development and reliability. In riscv/sdtrigpend, they implemented a new seed CSR to enable cryptographic RNG seeding and improved documentation for clarity and maintainability, using C and technical writing skills. For riscv/sail-riscv, they resolved a simulator bug by ensuring the instruction limit from the command line was correctly parsed and enforced, improving test reproducibility. In rust-lang/gcc, they added svadu and svade extension support to the RISC-V back-end, updating internal tables and tests in C and C++ to expand embedded systems compatibility.

March 2025 monthly summary for riscv/sail-riscv: Fixed a bug in the simulator where the parsed instruction limit (insn_limit) was not correctly stored after command-line parsing, ensuring the instruction limit is respected during simulation. This resolved inaccurate instruction counting and improved reliability of benchmarks and tests. The fix was implemented and committed (c8f8a24662917e4a95c3d62889cabd63ea64f1cb) with the message 'Fix --inst-limit'.
