primExpFromExp :: (MonadFail m, RepTypes rep) => (VName -> m (PrimExp v)) -> Exp rep -> m (PrimExp v)

Convert an expression to a PrimExp. The provided function is used to convert expressions that are not trivially PrimExps. This includes constants and variable names, which are passed as SubExps.

primExpFromSubExp :: PrimType -> SubExp -> PrimExp VName

Convert SubExps of a given type.

pe32 :: SubExp -> TPrimExp Int32 VName

Shorthand for constructing a TPrimExp of type Int32.

le32 :: a -> TPrimExp Int32 a

Shorthand for constructing a TPrimExp of type Int32, from a leaf.

pe64 :: SubExp -> TPrimExp Int64 VName

Shorthand for constructing a TPrimExp of type Int64.

le64 :: a -> TPrimExp Int64 a

Shorthand for constructing a TPrimExp of type Int64, from a leaf.

f32pe :: SubExp -> TPrimExp Float VName

Shorthand for constructing a TPrimExp of type Float32.

f32le :: a -> TPrimExp Float a

Shorthand for constructing a TPrimExp of type Float32, from a leaf.

f64pe :: SubExp -> TPrimExp Double VName

Shorthand for constructing a TPrimExp of type Float64.

f64le :: a -> TPrimExp Double a

Shorthand for constructing a TPrimExp of type Float64, from a leaf.

primExpFromSubExpM :: Applicative m => (VName -> m (PrimExp v)) -> SubExp -> m (PrimExp v)

Like primExpFromExp, but for a SubExp.

replaceInPrimExp :: (a -> PrimType -> PrimExp b) -> PrimExp a -> PrimExp b

As replaceInPrimExpM, but in the identity monad.

replaceInPrimExpM :: Monad m => (a -> PrimType -> m (PrimExp b)) -> PrimExp a -> m (PrimExp b)

Applying a monadic transformation to the leaves in a PrimExp.

substituteInPrimExp :: Ord v => Map v (PrimExp v) -> PrimExp v -> PrimExp v

Substituting names in a PrimExp with other PrimExps

primExpSlice :: Slice SubExp -> Slice (TPrimExp Int64 VName)

Convert a SubExp slice to a PrimExp slice.

subExpSlice :: MonadBuilder m => Slice (TPrimExp Int64 VName) -> m (Slice SubExp)

Convert a PrimExp slice to a SubExp slice.
