PROFILE
José Bacelar Almeida
Worked on the jasmin-lang/jasmin repository over a two-month period, focusing on correctness and reliability in low-level programming and formal verification. Addressed a critical edge case in AVX2 bitwise shift operations by aligning Jasmin’s shift semantics with the AVX2 specification, reducing subtle vectorization bugs and improving cross-platform consistency. Enhanced the theorem prover’s precision by introducing a [rigid] attribute for modulus-related hints in JWord.ec, strengthening the core hints mechanism and laying groundwork for future improvements. Utilized ECMAScript and Ec, applying expertise in bitwise operations, compiler development, and theorem proving to deliver targeted, maintainable enhancements and bug fixes.
