Debian Dropping Support For Older CPUs (distrowatch.com)
An anonymous reader shares DistroWatch's report that the Debian distribution will soon be dropping support for older, 32-bit processors.
The Debian project supports a wide range of hardware architectures, including 32-bit x86 CPUs. Changes are happening in Debian's development branches which will make older versions of the 32-bit architecture obsolete. Ben Hutchings provides the details:
"Last year it was decided to increase the minimum CPU features for the i386 architecture to 686-class in the Stretch release cycle. This means dropping support for 586-class and hybrid 586/686 processors. (Support for 486-class processors was dropped, somewhat accidentally, in Squeeze.) This was implemented in the Linux kernel packages starting with Linux 4.3, which was uploaded to Unstable in December last year. In case you missed that change, GCC for i386 has recently been changed to target 686-class processors and is generating code that will crash on other processors. Any such systems still running Testing or Unstable will need to be switched to run Stable (Jessie)." Hutching's announcement includes a list of processors which will no longer be supported after Debian "Jessie".

xp supports 32 bit so does 7 8 and 10.
So does debian.
its way to early to be killing off 32 bit support
They're not.
as low end machines where all 32 bit until just a few years ago so many are still in use.netbooks embedded etc.
I guess it's a good thing debian isn't killing off 32 bit support isn't it?
Did you try reading the summary? It says right there, minimum 686 class. Not that they're killing 32 bit support.
They aren't dropping 32-bit x86, just 486/586-level CPUs. AMD's K5 and K6, Intel's original Pentium and the MMX version; plus a few of the oddballs you don't hear much about these days, SiS, Cyrix, IDT Winchip, and VIA(C3, I don't know if they updated their newer parts).
Probably not zero impact; but those are some ancient devices; and Debian Stable will still support them until either 2018 or 2020 depending on whether they make it into LTS or not.

No they're dropping support for older cpus as the headline says. Those 30 year old cpu designs won't be supported in debian. No where in the headline does it imply debian 9 will be 64-bit only.
Maintaining useless old CPU architectures costs time and money. Given you can buy a Pentium 4 class CPU for $3 (or a quad core 2.8GHz i7 for $50), and a good developer's time is easily worth $100 per hour, it just plain doesn't make sense to support 20+ year old Intel chips.
If you believe differently, well - GCC is an open source project. How much are you paying to use it? Support it yourself, or spend $100 and get a new i686 capable computer.

He did read the summary. The summary states that Debian will be dropping support for "older, 32-bit processors." There should not have been a comma. The comma makes "older" and "32-bit" coordinate adjectives rather than having "older" modify "32-bit." It is written as if the 32-bit processors are the older processors. And while technically both adjectives apply and it is ambiguous, the implication of a normal reading would be that 32-bit processor support was being discontinued.
Unless you read the whole summary and happened to know which of the processor families have a 32-bit architecture. But many people aren't going to bother when the first sentence says they're discontinuing support for "older, 32-bit processors."
So his mistake is perfectly understandable.
Real lawyers write in C++
But you're not using a 30 year old system in production are you?
I'd wager the only place you'll find a 30 year old system is in production.
