Futhark.Transform.Rename

Description

This module provides facilities for transforming Futhark programs such that names are unique, via the renameProg function.

Synopsis

Renaming programs

renameProg :: (Renameable lore, MonadFreshNames m) => Prog lore -> m (Prog lore) Source #

Rename variables such that each is unique. The semantics of the program are unaffected, under the assumption that the program was correct to begin with. In particular, the renaming may make an invalid program valid.

Renaming parts of a program.

renameExp :: (Renameable lore, MonadFreshNames m) => Exp lore -> m (Exp lore) Source #

Rename bound variables such that each is unique. The semantics of the expression is unaffected, under the assumption that the expression was correct to begin with. Any free variables are left untouched.

renameStm :: (Renameable lore, MonadFreshNames m) => Stm lore -> m (Stm lore) Source #

Rename bound variables such that each is unique. The semantics of the binding is unaffected, under the assumption that the binding was correct to begin with. Any free variables are left untouched, as are the names in the pattern of the binding.

renameBody :: (Renameable lore, MonadFreshNames m) => Body lore -> m (Body lore) Source #

Rename bound variables such that each is unique. The semantics of the body is unaffected, under the assumption that the body was correct to begin with. Any free variables are left untouched.

renameLambda :: (Renameable lore, MonadFreshNames m) => Lambda lore -> m (Lambda lore) Source #

Rename bound variables such that each is unique. The semantics of the lambda is unaffected, under the assumption that the body was correct to begin with. Any free variables are left untouched. Note in particular that the parameters of the lambda are renamed.

renamePattern :: (Rename dec, MonadFreshNames m) => PatternT dec -> m (PatternT dec) Source #

Produce an equivalent pattern but with each pattern element given a new name.

renameSomething :: (Rename a, MonadFreshNames m) => a -> m a Source #

Rename the bound variables in something (does not affect free variables).

Renaming annotations

data RenameM a Source #

The monad in which renaming is performed.

substituteRename :: Substitute a => a -> RenameM a Source #

Perform a renaming using the Substitute instance. This only works if the argument does not itself perform any name binding, but it can save on boilerplate for simple types.

renamingStms :: Renameable lore => Stms lore -> (Stms lore -> RenameM a) -> RenameM a Source #

Rename some statements, then execute an action with the name substitutions induced by the statements active.

class Rename a where Source #

Members of class Rename can be uniquely renamed.

Methods

rename :: a -> RenameM a Source #

Rename the given value such that it does not contain shadowing, and has incorporated any substitutions present in the RenameM environment.
