%description
The MLIR project is a novel approach to building reusable and extensible
compiler infrastructure. MLIR aims to address software fragmentation,
improve compilation for heterogeneous hardware, significantly reduce
the cost of building domain specific compilers, and aid in connecting
existing compilers together.
