Futhark.IR.Syntax.Core

Description

The most primitive ("core") aspects of the AST. Split out of Futhark.IR.Syntax in order for Futhark.IR.Decorations to use these definitions. This module is re-exported from Futhark.IR.Syntax and there should be no reason to include it explicitly.

Synopsis

Documentation

Types

data Uniqueness Source #

The uniqueness attribute of a type. This essentially indicates whether or not in-place modifications are acceptable. With respect to ordering, Unique is greater than Nonunique.

Constructors

Nonunique

May have references outside current function.

Unique

No references outside current function.

data Space Source #

The memory space of a block. If DefaultSpace, this is the "default" space, whatever that is. The exact meaning of the SpaceId depends on the backend used. In GPU kernels, for example, this is used to distinguish between constant, global and shared memory spaces. In GPU-enabled host code, it is used to distinguish between host memory (DefaultSpace) and GPU space.

Constructors

DefaultSpace 
Space SpaceId 
ScalarSpace [SubExp] PrimType

A special kind of memory that is a statically sized array of some primitive type. Used for private memory on GPUs.

type Type = TypeBase Shape NoUniqueness Source #

A type with shape information, used for describing the type of variables.

type ExtType = TypeBase ExtShape NoUniqueness Source #

A type with existentially quantified shapes - used as part of function (and function-like) return types. Generally only makes sense when used in a list.

type DeclType = TypeBase Shape Uniqueness Source #

A type with shape and uniqueness information, used declaring return- and parameters types.

type DeclExtType = TypeBase ExtShape Uniqueness Source #

An ExtType with uniqueness information, used for function return types.

data Diet Source #

Information about which parts of a value/type are consumed. For example, we might say that a function taking three arguments of types ([int], *[int], [int]) has diet [Observe, Consume, Observe].

Constructors

Consume

Consumes this value.

Observe

Only observes value in this position, does not consume. A result may alias this.

ObservePrim

As Observe, but the result will not alias, because the parameter does not carry aliases.
