What is MLIR?

MLIR (Multi-Level Intermediate Representation) is a compiler infrastructure developed as part of the LLVM project. It is designed to represent code at various levels of abstraction, from high-level language constructs to low-level machine instructions. MLIR facilitates the construction of domain-specific compilers and tools by providing a flexible and extensible framework for representing, analyzing, and transforming code. It's commonly used for building compilers for new programming languages, optimizing existing compilers, and accelerating domain-specific computations such as machine learning.
