Description

A generic Python code generator which is polymorphic in the type of the operations. Concretely, we use this to handle both sequential and PyOpenCL Python code.

Synopsis

Documentation

data Constructor Source #

The class generated by the code generator must have a constructor, although it can be vacuous.

Constructors

Constructor [String] [PyStmt] 

emptyConstructor :: Constructor Source #

A constructor that takes no arguments and does nothing.

compileCode :: Code op -> CompilerM op s () Source #

compilePrimType :: PrimType -> String Source #

The ctypes type corresponding to a PrimType.

compilePrimTypeExt :: PrimType -> Signedness -> String Source #

The ctypes type corresponding to a PrimType, taking sign into account.

compilePrimToNp :: PrimType -> String Source #

The Numpy type corresponding to a PrimType.

compilePrimToExtNp :: PrimType -> Signedness -> String Source #

The Numpy type corresponding to a PrimType, taking sign into account.

defaultOperations :: Operations op s Source #

A set of operations that fail for every operation involving non-default memory spaces. Uses plain pointers and malloc for memory management.
