$ cd /opt/kde*/bin
$ file kate
kate:		ELF 32-bit MSB executable SPARC32PLUS Version 1, V8+ Required, UltraSPARC1 Extensions Required, dynamically linked, stripped

Has likely been compiled with " -xtarget=ultra -xarch=v8plus "

This is what you need to use if you want to address a large audience.
the potential users here are all UltraSparc computers. ( i.e UltraSparc 1, UltraSparc II , UltraSparc III & IV )

if you target UltraSparc III specifically with :
-xtarget=ultra3 -xarch=v8plusb

Or a unic chip like UltraSparc IIIi :
-xtarget=ultra3i -xarch=v8plusb -xcache=64/32/4:1024/64/4

you get better performance but have to make lots of binary distributions, one for each CPU chip,
probably more than 5 different sets, and then handhold all the people who
cant be bothered to find out which exact binary distro that will run
on their particular workstation.

Pls Note that -xarch=v9  generates 64 bit binaries.
