Project something from the global environment.

Set the value of the global environment.

Update the global environment using the provided function.

Should we avoid as much vectorisation as possible?

Set by '-f[no]-vectorisation-avoidance'

Add a mapping between a global var and its vectorised version to the state.

Remove the mapping of a variable in the vectorisation map.

Check whether a variable has a vectorisation declaration.

The first component of the result indicates whether the variable has a NOVECTORISE declaration. The second component contains the given type and expression in case of a VECTORISE declaration.

Get the set of global parallel variables.

Get the set of all parallel type constructors (those that may embed parallelism) including both both those parallel type constructors declared in an imported module and those declared in the current module.

Determine the vectorised version of a TyCon. The vectorisation map in the global environment contains a vectorised version if the original TyCon embeds any parallel arrays.

Add a mapping between plain and vectorised TyCons to the global environment.

The second argument is only to enable tracing for (mutually) recursively defined type constructors, where we must not pull at the vectorised type constructors (because that would pull too early at the recursive knot).

Add a mapping between plain and vectorised TyCons to the global environment.

Get the set of all vectorised type constructors.

Lookup the vectorised version of a DataCon from the global environment.

Add the mapping between plain and vectorised DataCons to the global environment.

Lookup the PA dfun of a vectorised type constructor in the global environment.

Associate vectorised type constructors with the dfun of their PA instances in the global environment.
