oh please .. no.

Although I don't have much of a preference for 32bit sparc userland, as
there is no kernel support for old SPARC gear, but anything substantial
on why not, Dennis?

I enjoy historical and archaeological computing as much as the other old
grey beard suspender wearing UNIX geeks but it is largely just a waste
of time.  A curiosity to be sure. However nothing more. At least we have
32-bit ppc FreeScale and Motorola type hardware literally everywhere but
I have not seen 32-bit sparc in the wild for at least a decade.

Running ILP32 software on a 64-bit CPU sure seems unpopular these days...
(but it's still half the memory and bandwidth nonwithstanding the
beating x32 took not too long ago).


I agree with a "bit less" memory. A "bit less" bandwidth?  Maybe.
However the overhead in a code base isn't worth the effort.
