None of the items you listed are SPARC-specific or absent from
other proprietary compilers. You previously said: "... relatively small
gap between gcc on x86 and icl [sic] ...", which means that the gap is in
the SPARC-specific part of GCC that Sun is ignoring and not fundamental to
GCC.
If Sun and its partners do not care about GCC performance on
SPARC, no one else will do it for them. No points for heckling from the
sidelines.

This is an oversimplified assertion. A small but lucrative
portion of the market cares about the absolute best performance and
specific HPC Features, while most of the market cares about good
performance and portability. Any customer who wants a proprietary,
lock-in compiler solution would chose Sun CC with GCC compatibility, with
or without "GCC for SPARC".
If Sun want customers to have a better experience with GCC, it
should help improve GCC.
