Here is information I've received about the performance of GCC on
certain very new Sparc machines:

The GNU compiler does not really support the Super SPARC processor that
is used in SPARC Station 10 and similar class machines.  You can get
code that runs by specifying @samp{sparc} as the cpu type; however, its
performance is not very good, and may vary widely according to the
compiler version and optimization options used.  This is because the
instruction scheduling parameters designed for the Sparc are not correct
for the Super SPARC.  Implementing scheduling parameters for the Super
SPARC might be a good project for someone who is willing to learn a
great deal about instruction scheduling in GNU CC.
