This portal is to open public enhancement requests against IBM Z Software products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

Too little benefit? Drive up the compile time too much for testing the generation of an unknown instruction? For me that's very astonishing! The compiler has to know which instruction has been generated. IMHO(!!!) that code is in one or more special sections called via otherwise clauses. And that addional code drives up the compile time too much?
I think that point has to be discussed in our next meeting in May 2017 in Frankfurt!
we think this would drive up the compile time too much for too little benefit
we are investigating the compile-time cost of doing this
a question about this RFE was sent as part of the response to the parallel RFE for C/C++
we are discussing this with the backend team
