I am new at Unix field, so if this question is too trivial, please take
patience... :-)
By using "file" command I found some of binaries I built are
"SPARC32PLUS V8+" while the others are "SPARC32 V8" only. What's the
difference between the two? Also I find V8+ format executable can not
be recoginzed by Solaris 2.6, in other words, it's not runnable.
Any one can help to explain that ?

The V8 binary can run on any sparc system, the V8+ has been compiled to
use UltraSparc specific ops (like VIS) and therefore can only run on a
UltraSparc. (V9 is also UltraSparc only, and will only run on a 64-bit
Solaris 7 or later kernel on an Ultra.)

To be more precise, V8+ is just "SPARC v9 instructions", not VIS (i.e.,
64 bit SPARC, not UltraSPARC specific)
v8plusa includes vis 1.0
