The interpreter compiled with GCC is, on the average, 15% slower than the version which was compiled with the Sun 3.5 C compiler. I had been under the impression that GCC produced better code than the Sun C compiler. I have also tried smaller benchmarks, but they also indicate that Sun CC produces better code. Did I goof some place in the compilation of GCC, or does Sun CC produce better code?? Thanx for your help, arman. -- Arman Bostani // UCLA Computer Science Department // +1 213-825-3194 3417 Boelter Hall // Los Angeles, California 90024-1596 // USA arman@CS.UCLA.EDU ...!(ucbvax,rutgers)!ucla-cs!arman
