RFC: Enable vectorization of call instructions in the loop vectorizer

[James Molloy]

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.

 

Again, sorry for the churn!

Hi Renato,

 

Thanks. Updated patch attached - I've also added a function for querying if
a libfunc reads or writes the rounding mode for legalization.

 

Cheers,

 

James

"getTransformedFunction()"? That way it's obvious that it's doing
*something*, but not tied to vectorization or scalarization and suggests the
user looks at the doxygen.

 

Yeah, I could go for that. ;)

 

I'd wait until Hal, Nadav and Arnold had a look at it before committing, but
my concerns were addressed, and I'm happy with it.

 

cheers,
