PROFILE
Neelay Sant
Neelay Sant contributed to the tezos/riscv-pvm repository by developing core features for RISC-V atomic memory operations and enhancing the precision of control flow graph step counting. He implemented and standardized atomic operations across interpreter and JIT paths, refactored legacy naming for clarity, and integrated reservation-set handling to ensure alignment and test consistency. Neelay also introduced an instruction address mapping module to support sequence analysis, using Rust and C to design robust data structures and memory management routines. His work demonstrated depth in compiler development and low-level programming, focusing on maintainability, accurate program analysis, and groundwork for future JIT integration.

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.
