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.
