Re: z14 PoO Available - VFLL instruction

[MELVYN MALTZ]

And wouldn't it be great if it was called z390 and available on a website 
called www.z390.org and if just a few Java programmers could be bothered to 
spend a few hours achieving just that as Don, Melvyn, Abe and several others 
tried to do over the past years...doh.


And while I'm on the subject, does anyone remember that a few months ago I 
wanted the PoOPS ripped apart and reconstructed so that every single 
instruction had a page to itself with links ?
My suggestion got trashed...I still can't believe that the guys and gals 
here have so little imagination.


53 years of assembler coding and still no-one listens to me.

And just to annoy people even more, enhancing the IBM360 architecture is 
like redesigning the T-Rex...it's already extinct guys...time to move on.

But wouldn't be great if the PoO could just be fed into a software 
emulator creator (in machine-readable format, of course) and out would 
come a software emulator. And the another process could create all the 
chips and microcode. That way the PoO would always exactly match the 
processor.

All,

In the new PoO, on page 24-26, Programming Note for VFLL instruction,
there is what seems to be another copy-paste error. I quote:

*Programming Note*: If a trapping IEEE exception is
   encountered during execution of VECTOR LOAD
   LENGTHENED it is model dependent if the VIX in
   the VXC field is the index of the source or target element
   unless the IBM z/Architecture Principles of
   Operation is installed in which case it is always the
   index of the source element.

Beats me how the PoO could be installed in the processor,
but maybe I'm taking things too literally?

Can it be it should have referred to the vector-enhancement
facility 1 ?

Kind regards,
Abe Kornelis

Except that currently there are far more defects in the PoO than in the
chips and microcode.

Re: z14 PoO Available - VFLR instruction

[Abe Kornelis]

All,

another typo in the new PoO. This time on page 24-27, where extended
mnemonic VLED
is specified as taking two vector registers and three masks, but the
VFLR equivalent has
M4,M4,M5 which I think should have been M3,M4,M5.

Kind regards,
Abe Kornelis

Re: z14 PoO Available

[Abe Kornelis]

All,

In the new PoO, on page 24-14, the extended mnemonics for VFCHE are listed.
It looks like the last one went missing: WFKHEXBS with mask values 4,12,1

I assume it should have been present?

Kind regards,
Abe Kornelis.

Dan,

thanks for the explanation. I've marked order code 20 as unavailable.

Thanks also for your answers to my other posts.

Kind regards, and do enjoy your retirement!

My favourite pet peeve since ages:

"two-column material"

how on earth is someone with a reduced size screen (let alone
tablet or mobile) supposed to read that (without printing!) ?
