Hey, as one of the key co-designers of the latest XPLINK (and
hopefully last) calling convention for C/C++ on IBM/390 I would
actually say the history is a very interesting. This latest design
was done for performance reasons but with a strong thought to
compatibility (hence some of the complexities of the design). The
previous calling conventions were also chosen for valid reasons.
