Based on the announced capability to use new (to COBOL) TUNE and ARCH compiler

backend.
I heard a rumour that COBOL was going to use the same back-end that the
Java JIT uses. It was also suggested PL/1 and C/C++ would also be using
the same universal back-end in the future.
Having seen the output of that backend during a recent research project in
MetalC, I am quite impressed by its capabilities to *really* optimize the
instruction stream, unlike the sadly lacking current COBOL backend.
I think we're going to like it. A *lot*.
At least, I have some real hope that we will, though this *is* IBM we are
talking about. Do they really want to significantly optimize the existing
COBOL executable base as it is recompiled for maintenance and enhancements,
reducing MSU usage all over the place? They have, time and again, shown
themselves quite capable of deliberately reducing the effectiveness of new
technology to preserve their revenue stream for a few more quarters.
We will see.

It has taken us a while, but we now have a modern backend (code generator
and optimizer) for COBOL that can exploit the latest hardware, and will
support DFP, AMODE 64 and many of the other z/OS system features that we
have not be able to exploit in the past.
Is that new backend bespoke for COBOL or is it shared with PL/1, C/C++,
Java?
