[Codegen] Add LowerStructuralPCFPass (#22915) Adds the LowerStructuralPCFPass which lowers structural PCF operations to SCF: - pcf.generic is lowered to scf.execute_region - pcf.loop is lowered to scf.forall - pcf.branch_cond_return is lowered to cf.cond_br The pass uses the scope attribute on each operation to determine how to generate worker IDs and counts for the lowered operations. Synchronization barriers are inserted when sync_on_return is set. Also adds loadStructuralLoweringDependentDialects to PCFConversionDialectInterface, allowing external dialects to register dependent dialects needed during lowering.
IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.
