LLVM RISC-V Target Backend Instruction for Reshape Operator

LLVM is an open-source collection of compiler and tool-chain technologies designed to be modular and reusable. Its goal is to provide a modern Static Single Assignment compilation strategy capable of supporting the both static and dynamic compilation of arbitrary programming languages. ONNX is an open format built to represent machine learning models. ONNX defines a common set of operators, the building blocks of machine learning and deep learning models, and a common file format to enable artificial intelligence developers to use models with a variety of frameworks, tools, runtimes, and compilers. RISC-V is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. This paper presents an implementation of a backend instruction for compiling Reshape operator from ONNX machine-learning standard. This instruction has the purpose to compile the operator and generate low-level code specific for RISC-V architecture.
