I heard a lot of this compiler and expected a better results for it. 
 Using -O2 -mtune=nocona for gcc4 and -O2 -mtune=em64t for open64 on 
em64t machine in 32-bit mode, I found preliminarily  that pathscale 
compiler generates about 10% worse and 30% larger code (text segment) 
for SPECInt2000.  It is also 70% slower than gcc4.  I just hope results 
for 64-bit mode, amd machine, or SPECFP2000 are better.
