PROFILE
Neelay Sant
Worked on the tezos/riscv-pvm repository, focusing on core architectural enhancements for RISC-V emulation and JIT compilation. Developed and standardized atomic memory operations across interpreter and JIT paths, improving alignment checks and naming conventions for maintainability. Introduced a dedicated instruction address mapping module to support sequence analysis, using Rust and C to implement robust data structures and initialization patterns. Enhanced control flow graph step counting by refining the step-counting mechanism and introducing precise exit tracking, which improved loop and termination analysis. The work demonstrated depth in low-level programming, compiler optimization, and systems programming, with an emphasis on code clarity and testability.

Oct 1, 2025Monthly work summary for 2025-10 focusing on tezos/riscv-pvm: Implemented Control Flow Graph step counting precision enhancement to improve analysis of program termination and loop behavior. Refactored the step-counting mechanism and introduced exit_delta to accurately account for steps when a program exits after a specific outcome, increasing precision in loops and termination scenarios. This work improves reliability of JIT sequence analysis and reduces miscounted steps in edge cases.

Jul 1, 2025Month: 2025-07 — Architecture groundwork for Tezos riscv-pvm continues with a new instruction address mapping module to support sequence analysis. Implemented design for address-to-info mappings with AddrMap and InstrMap, plus a builder for consistent initialization. The module is currently isolated for testing ahead of JIT integration.
