PROFILE

Mikhail R. Gadelha

Mikhail worked on enhancing cross-platform robustness and vectorization in the esbmc/esbmc and espressif/llvm-project repositories. He improved HTML report generation and execution engine stability in esbmc by refactoring configuration handling, clarifying CLI usage, and consolidating breakpoint logic, which streamlined debugging and increased portability. In espressif/llvm-project, Mikhail focused on the RISC-V backend, enabling vrgather for constant indices and addressing build and code generation issues by removing problematic assertions and adding safety checks. His work, primarily in C++ and LLVM IR, demonstrated strong skills in compiler development, low-level optimization, and testing, delivering deeper reliability and correctness to complex toolchains.

Summary for 2025-01: Focused RISCV backend work in espressif/llvm-project delivering build stability, safety, and vectorization improvements. Key outcomes include enabling vrgather for in-bounds constant indices via a refactor of matchSplatAsGather, fixing rv32 builds by removing a static_assert in dup2.cpp, adding a null-pointer check in RISCV lowering to prevent potential clang crashes, and introducing a regression test for PR119527 to cover 32-bit to 64-bit promotion (add_shl_sext). These changes reduce CI flakiness, harden the toolchain, and improve correctness of vector code paths. Technologies demonstrated: C++, LLVM, RISCV backend development, regression testing, and vectorization.

December 2024: Delivered cross-platform robustness and improved reporting for esbmc/esbmc. Implemented HTML report improvements, reinforced execution engine stability (breakpoints and recursion), cleaned test infrastructure, and fixed build issues across Clang 18+. Resulting changes reduce debugging time, improve portability, and deliver clearer, more actionable outputs for stakeholders.
