Enable vectorization of call instructions in the loop vectorizer

[James Molloy]

Hi Renato,

Valid question! Originally yes that was the intent, but after having tried implementing this interface I realized of course that we need to query if functions are vectorizable in const context.

Therefore, the has* functions are able to be const, and the get* are not and take a Module& to code generate into.

Sorry for the churn – one last version! This one adds predicate functions “has*”, and adds a Module& parameter to the “get*” functions to allow them to create the function on demand if needs be.

Hi James,

I may be wrong, but I'd assume the has* functions would return get* != NULL, so not really value added.

Are you implementing them in a different way?

cheers,
