I listened to the Oracle webcast about their new upcoming development tools. They mentioned that their C/C++ compiler "far outperforms all open source alternatives".
I asked the question if they have any benchmark URL supporting this statement.
They actually answered. They said that they stopped publishing benchmark results. But they said that on Intel platform their compiler outperforms gcc by 43% for integers and 3X for floating point. And on Sparc they outperform gcc by 80% on integers and 4X on floating point.
And "LLVM produces no competitive results", that's what they said.
I have the feeling that all mentioned results are just for marketing people who like to hear high percentage numbers not really understanding what they are about, or maybe achievable on some specific testcases. Actually, what really matters is the performance of some real life application with mix of various things in it, not just some specific test algorithm.
Are there any benchmark comparisons available, comparing LLVM C/C++ compiler with gcc, Intel, Oracle (Sun) compilers?
