PROFILE
Kyle Huey
Worked on the DynamoRIO/dynamorio repository, focusing on expanding x86 instruction set support and improving disassembly robustness for modern Intel CPUs. Over four months, implemented decode and encode support for new instructions such as SERIALIZE, MOVDIR64B, and AVX512 extensions, updating decoding tables and API headers to ensure compatibility and accuracy. Enhanced test coverage and reliability by enabling additional binutils tests and refining operand handling. Addressed correctness issues in the x86 decoder and disassembly pipeline through targeted bug fixes and assertion-based refactoring. Utilized Assembly and C, applying skills in low-level programming, compiler development, and instruction set architecture to strengthen instrumentation tooling.

Mar 1, 2025March 2025: DynamoRIO/dynamorio — Implemented a correctness-focused fix in the x86 decoder by enforcing ModR/M value f8 for xbegin/xabort. This change replaces the previous broader acceptance, improving decoding accuracy and reducing false positives in dynamic instrumentation.

Nov 1, 2024November 2024 highlights: Implemented Intel SERIALIZE support in DynamoRIO/dynamorio to improve compatibility with newer Intel CPUs and ensure correct instrumentation of serialized operations. This included decode/encode support and updates to decoding tables and API headers to recognize SERIALIZE. The work is anchored by commit 55c707afe840132f90f48c247134050596e01fa0 ("Add decode/encode support for the Intel SERIALIZE extension. (#7096)"). No major bugs reported this month; the feature lays groundwork for broader deployment and reliability on modern hardware. Technologies demonstrated include low-level instruction decoding/encoding, API/header maintenance, and cross-CPU compatibility engineering.
