Futhark.Representation.AST.Attributes.Constants

Description

Possibly convenient facilities for constructing constants.

Synopsis

class IsValue a where
- value :: a -> PrimValue
constant :: IsValue v => v -> SubExp
intConst :: IntType -> Integer -> SubExp
floatConst :: FloatType -> Double -> SubExp

Documentation

class IsValue a where Source #

If a Haskell type is an instance of IsValue, it means that a value of that type can be converted to a Futhark PrimValue. This is intended to cut down on boilerplate when writing compiler code - for example, you'll quickly grow tired of writing Constant (LogVal True) loc.
