Where do I find more info about new z15 instruction SORTL listed in Sept. APAR
but not in POP
I asked IBM about this pre-GA and was told that the doc was
*deliberately* left out of PoOp because there were not yet any
exploiters! WTF? How can anyone exploit something that isn't documented?
My "push back" on that was left unanswered... :-\
Thinking it through on my own, I came to realize IBM has deliberately
decided *NOT* to give SYNCSORT an opportunity to exploit this
performance enhancement before they get around to doing so in DFSORT.
So, in answer to my original question, they should have said there were
not yet any *IBM* exploiters...
