PROFILE
Arun Thangamani
Arun Thangamani developed an AVX2 8-bit integer dot product operation, DotInt8Op, for the X86Vector dialect in the llvm/clangir repository. He defined the operation in TableGen and implemented the lowering logic in C++, enabling the feature to map directly to the LLVM intrinsic llvm.x86.avx2.vpdpbssd. This work supported both 128-bit and 256-bit vector widths, allowing efficient int8 dot-product code generation on AVX2 backends. Arun’s contribution demonstrated depth in low-level programming, vectorization, and compiler development, addressing the need for optimized integer dot product operations in modern vectorized workloads and integrating seamlessly with the existing LLVM infrastructure.
