Hi,

I think that maybe we can already deprecate supporting 32 bit builds.



I expect that at some point even the linux kernel will drop support.

The impacted runtimes will probably be very low.

And, maybe with PHP 9, or PHP 10, or with a future version that might exist in about 6/7 years, completely drop 32 bits support. As far as I checked a bit, all major OSs where PHP could run already dropped or will drop support for 32 bits builds.

100% agree. We are already running out of space on some bitmasks (there are a couple with exactly one bit left, or even none in the case of GC flags) for 32 bit support.

Dropping 32bit builds entirely is an option I would support as well.

Would you be able to help me writing an RFC for it as I don't have enough knowledge of PHP internals to know where 32bit build is going to be problematic there as well?
