# Annotated Exprs

collectAnnTypeArgs :: AnnExpr b ann -> (AnnExpr b ann, [Type])

collectAnnDictArgs :: AnnExpr Var ann -> (AnnExpr Var ann, [AnnExpr Var ann])

collectAnnTypeBinders :: AnnExpr Var ann -> ([Var], AnnExpr Var ann)

collectAnnValBinders :: AnnExpr Var ann -> ([Var], AnnExpr Var ann)

Collect all consecutive value binders that are not dictionaries.

isAnnTypeArg :: AnnExpr b ann -> Bool

# PD Functions

replicatePD

Arguments

:: CoreExpr | Number of copies in the resulting array.
-> CoreExpr | Value to replicate.
-> VM CoreExpr |

Produce an array containing copies of a given element.

emptyPD :: Type -> VM CoreExpr

An empty array of the given type.

packByTagPD

Arguments

:: Type | Element type.
-> CoreExpr | Source array.
-> CoreExpr | Length of resulting array.
-> CoreExpr | Tag values of elements in source array.
-> CoreExpr | The tag value for the elements to select.
-> VM CoreExpr |

Select some elements from an array that correspond to a particular tag value and pack them into a new array.

    packByTagPD Int# [:23, 42, 95, 50, 27, 49:]  3 [:1, 2, 1, 2, 3, 2:] 2
      ==> [:42, 50, 49:]

combinePD

Arguments

:: Type | Element type
-> CoreExpr | Length of resulting array
-> CoreExpr | Selector.
-> [CoreExpr] | Arrays to combine.
-> VM CoreExpr |

Combine some arrays based on a selector. The selector says which source array to choose for each element of the resulting array.

liftPD :: CoreExpr -> VM CoreExpr

Like `replicatePD` but use the lifting context in the vectoriser state.

# Scalars

isScalar :: Type -> VM Bool

zipScalars :: [Type] -> Type -> VM CoreExpr

scalarClosure :: [Type] -> Type -> CoreExpr -> CoreExpr -> VM CoreExpr

# Naming

newLocalVar :: FastString -> Type -> VM Var

Make a fresh local variable with the given type. The variable's name is formed using the given string as the prefix.
