-------------------------------------------------------------------------------
-- These are the main simplifier phases used in DPH.
--  The phase is numbered after the set of bindings that are inlined in that
--  phase. We start from the "outermost" combinators produced by the
--  vectoriser and work our way down to the Data.Vector streams.
--

-- Inline bindings in user code, and closure functions.
-- This is dph-common-vseg:D.A.P.Lifted.Closure
#define PHASE_USER      [4]

-- Inline combinators that work on PArray and PData.
-- This is dph-common-vseg:D.A.P.PArray
#define PHASE_PA        [3]

-- Inline combinators from the unlifted backends
-- This is dph-prim-par:D.A.P.Unlifted.Parallel
--     and dph-prim-par:D.A.P.Unlifted.Sequential
#define PHASE_BACKEND   [2]

-- Inline combinators for distributed arrays.
-- This is dph-prim-par:D.A.P.Unlifted.Distributed
#define PHASE_DIST      [1]

-- Inline combinators for Data.Vector
#define PHASE_STREAM    [1]

-- Inline stuff in inner loops.
#define PHASE_INNER     [0]

-- More fine-grained inliner pragmas that we use to annotate the actual
-- bindings. When debugging it's useful to control exactly what gets inlined.
