I (or somebody else from Oracle) will need to be the one committing/contributing the actual SLEEF code itself in the end. Can you take on the work of implementing the actual plan/logic and make sure it's all effectively ready for integration?

@vidmik Thanks for pushing forward this work.
Sure, I can take the work.

Just several questions, Sorry, as this is the first time I do this kind of work in jdk.
In this pr, we already have the pre-generated sleef files and the scripts to generate it, what we are missing is the sleef original file (in my understanding, we also need to checkin them), besides of sleef original files, do we need any other files or document? In particular, do you mind to clarify further about `plan/logic` mentioned above?
