   Depends which Sun compiler you're talking about.  I was favorably impressed
   by g++'s object code and encouraged some friends to try it out.  They 
   installed gcc and benchmarked it, but they had a newer Sun C++ compiler than 
   I do.  It trounced g++; they tell me their code runs in about 40% more time 
   when compiled with g++.  This was about two months ago--I don't know the 
   name or version number of the Sun C++ compiler they were using, but they 
   were comparing it to g++ 2.6.3.  (To be fair, g++ optimization for Sparc 
   seems to do a better job in 2.7.0 than it did in 2.6.3.)

My benchmarks had g++ heavily outperform sun's 3.0 c++ compiler. Sun's
4.0 c++ compiler (their latest as far as I know) is closer to g++ but
g++ still easily outperforms it most of the time.

ps. I ran my test on sparcstation 5 and used the following gcc flags:
 -mno-epilogue -mv8 -msupersparc -O6 -fforce-mem -fforce-addr 

I tried many combinations of sun's flags but gcc/g++ always
outperformed sun (although in some cases by a very small margin).
