tvm::tir::MatchBufferRegionNode Class Reference

Match introduces a constraint that the source buffer region can be remapped to the data layout specified by the buffer field. The constraint can be checked in later part of lowering (or optionally during runtime). More...

Detailed Description

Match introduces a constraint that the source buffer region can be remapped to the data layout specified by the buffer field. The constraint can be checked in later part of lowering (or optionally during runtime).

MatchBufferRegion provides a mechanism to represent data layout and compactness constraints in low-level hardware primitives in the IR and defer the check after the sequence of transformations.
