Futhark.IR.Primitive

Description

Definitions of primitive types, the values that inhabit these types, and operations on these values. A primitive value can also be called a scalar.

Essentially, this module describes the subset of the (internal) Futhark language that operates on primitive types.

Synopsis

Types

data IntType Source #

An integer type, ordered by size. Note that signedness is not a property of the type, but a property of the operations performed on values of these types.

Constructors

Int8 
Int16 
Int32 
Int64

Operations

data Overflow Source #

What to do in case of arithmetic overflow. Futhark's semantics are that overflow does wraparound, but for generated code (like address arithmetic), it can be beneficial for overflow to be undefined behaviour, as it allows better optimisation of things such as GPU kernels.

Note that all values of this type are considered equal for Eq and Ord.

data Safety Source #

Whether something is safe or unsafe (mostly function calls, and in the context of whether operations are dynamically checked). When we inline an Unsafe function, we remove all safety checks in its body. The Ord instance picks Unsafe as being less than Safe.

For operations like integer division, a safe division will not explode the computer in case of division by zero, but instead return some unspecified value. This always involves a run-time check, so generally the unsafe variant is what the compiler will insert, but guarded by an explicit assertion elsewhere. Safe operations are useful when the optimiser wants to move e.g. a division to a location where the divisor may be zero, but where the result will only be used when it is non-zero (so it doesn't matter what result is provided with a zero divisor, as long as the program keeps running).
