Compiler Stacks: XLA, TVM, MLIR
Every deployment path covered so far in this folder eventually hands a graph to something that turns it into device code, and up to now that "something" has mostly been a fixed toolkit: TensorRT's builder, OpenVINO's plugins, a vendor NPU SDK. This page steps back and looks at the compilers underneath those toolkits and behind the frameworks themselves — what a graph compiler actually does that a kernel library doesn't, and the handful of stacks (XLA, TVM, MLIR, and torch.compile) that show up across nearly every deployment target in this section.
