MLIR: one compiler, many IRs

LLVM relies on a single IR for everything. MLIR bets on the opposite, and the diagram traces why that bet pays off for AI compilers.

These are my notes from learning MLIR, why LLVM's one-IR-for-everything model breaks down, what a dialect actually is, and how progressive lowering replaces LLVM's fixed compiler stages. The diagram above is the source; pan and zoom into it directly.
