1. AFAIK MC doesnt have an Intel CPU. So he cant really build specifically for Intel using ICC.
2. ICC is not free. The complete/paid version has the complete optimisations. The demo/free doesnt have all. So it would be similar to MSVC
3.Performance gains would probably be very limited.
4.you can try cross-compiling PM in linux with GCC4.7 for windows. That will definitely give you much much more control over optimisations. And you can build with march=native. So if you have an ivy bridge, you will get a browser built specifically using ivy-bridge instruction set.
Of course, it will still perform like PM, but you will get the satisfaction of using the fastest possible browser based on mozilla code.
5.Other possible PGO+SSE3+ICC build FF clones are :
Lawliet firefox and PCX firefox.
6. MC believes AMD processors are faster than Intel. So in any case he wont build for Intel.

Thank you for your reply stravinsky.
Moonchild can build with ICC, but not having an Intel CPU does prevent him from testing performance improvements, which is why a tester's group could be made.
I wasn't aware that ICC was paid, and if it follows similar brand products, licensing fees might be expensive. The fact that the free version lacks the complete optimization set is quite a letdown, unfortunately.
I do wonder whether performance gains would be that limited, even putting aside specific content that would benefit most from it.
The instruction set update of Ivy Bridge was smaller than expected over the previous generation, and most seem to improve over cryptography and little else, which is understandably moot for browser performance.
What do you think of Lawliet Firefox, PCX Firefox and Waterfox when compared to Pale Moon?
AMD had a good run during the Athlon 64 era, almost close to Intel's market share at the time, but ever since Intel released Core 2 Duo, AMD has been on a downslide ever since, up to the point AMD publicly stated it no longer competes with Intel in terms of performance, so that alone should point out that AMD simply isn't up to scratch, regardless of personal opinions
