Re: dropping CONFIG_IA32_SUPPORT from ia64
I will offer the opinion that support of the IA32 ABI is
important. That is, the ability to install and run
an IA32 binary (doesn't matter how, just matters it is
the same binary as used on an IA32 machine).
And I am certainly happy with the IA32-EL approach.
This feature provides a bridge for a customer with certainly
a lot more IA32 machines in their shop. No customer will
have a dominate number of IA64 systems. Hence the
ability for the IA64 to fit it and blend it, and run
any code there, and in addition do its special work,
is a much, much easier sell.
The reverse story, that IA64 runs only IA64 binaries,
is a tough sell.

Acrobat is the only thing I use it for... and firefox when I *have*

I think that IA32 support is important for those (few) of us who use
Zx2000 or similar as workstations on Debian. And I'm hoping that that
number will increase now that some of the 2nd generation clusters are
reaching eol, so there should be starting to be zx6000 on the 2nd hand
market relatively cheap. I've seen a few here for $1300AUD --- and
even as old (1.2GHz) machines they beat the pants off anything else
you can buy here at that price.
The new system calls are irrelevant for most apps.
