v59 v60 26 26 This pragma can also be used for imported functions `f`. In this case, `f_v` and a suitable vectorisation mapping of `f` to `f_v` is exported implicitly — just like `RULES` applied to imported identifiers. By vectorising imported functions, we can vectorise functions of modules that have not been compiled with `-fvectorise`. This is crucial to using the standard `Prelude` in vectorised code. 27 27 28 ''Parallelism:'' A vectorised value is marked as parallel if its code includes a parallel value or if it includes any parallel types. The detailed rules are in the '''Vectorisation Avoidance''' paper. 28 ''Parallelism:'' . 29 29 30 30 '''IMPLEMENTATION RESTRICTION:''' Currently the right-hand side of the equation —i.e., `e`— may only be a simple identifier '''and''' it must be at the correct type instance. More precisely, the Core type of the right-hand side must be identical to the vectorised version of `t`.
