Summary: Improve IPA for propagating scalar strings into functions
Key: SYSTEMML-2284
URL: https://issues.apache.org/jira/browse/SYSTEMML-2284
Project: SystemML
Issue Type: Task
Reporter: Matthias Boehm
So far strings are not subject to IPA scalar propagation into functions (and
the determination if it would be safe to do so). However, there are a number of
functions that pass parameters like "train" / "eval" used in branches. If we
would propagate consistent scalars into this functions, we can fold these
constant predicates, removal unnecessary branches, and finally inline
single-block functions into the caller.
