Andreas, I think including spec numbers generated from more, er, mainstream compilers would be a great idea. All compilers optimize, but it's really not clear if Intel's compilers are much used in the real world. I recently looked up some old traffic on the Intel thread on this subject. I dug up this post from an Intel insider:

I would admit that few developers use Intel's compiler to build 100% of the application (i.e. exclusively). However, I will stand behind the statement that I made before that A LOT of software uses the Intel compiler for key performance parts (i.e. you might have your performance critical functions in a single or couple of source files that are compiled with the Intel compiler and then linked under MS VC with the rest of the sources - A VERY COMMON practice). Message 13880022

You can read this two ways, of course. One way is that the Intel compiler is good for critical stuff. The way I read it is that it's too fragile to just go out and compile your whole application with it, unless your application happens to be in the SPEC suite. Intel has turned SPEC into a compiler+hardware benchmark, rather than a hardware benchmark, and I think that needs to be made clear. Showing Spec scores compiled with Microsoft compilers would be a lot more indicative of what most users could expect.

Cheers, Dan.
