Detailed Description

An analysis for type-inference for VPValues.

It infers the scalar type for a given VPValue by bottom-up traversing through defining recipes until root nodes with known types are reached (e.g. live-ins or load recipes). The types are then propagated top down through operations. Note that the analysis caches the inferred types. A new analysis object must be constructed once a VPlan has been modified in a way that invalidates any of the previously inferred types.
