Using Intel C++ Compiler to build Firefox on Windows

[xunxun]

I have built some Firefox editions using Intel Compiler from Firefox 10.

At present, I think the build process, patches, and some bug workaround methods are very stable, so I have reconstructed my wiki.

Wiki English Edition :

http://code.google.com/p/pcxfirefox/wiki/MozillaBuiltICC

Wiki Chinese Edition :

Hope this can be useful for the people interested in building Firefox using Intel Compiler on Windows.

Latest Firefox 13 x86 edition using ICC13 is here:

If you have some problems, you can discuss with me. I won't continue Firefox ICC edition building until I have a strong need because of very much time cost.

Thanks.

Thank you sharing those instructions.

Did you run any test suite?

Here is some test results:

official13 my13 ICC

sunspider 330.8ms +/- 0.7% 284.8ms +/- 1.1%

V8 4803 5084

Kraken 5140.2ms +/- 0.7% 4678.9ms +/- 0.9%

Aquarium 15-16 fps 22-30 fps

Tested on Win7 x64 and Intel Core2 CPU

Doesn't look bad at all.

Another question, I just read your wiki and saw several issues with Intel C++ compiler. Have you reported all the issues yet?

Thanks again!

I haven't.

Because when I build using IPO&PGO, I usually don't use -Zi (It will cause time long or some build stop if a very many objs), which make me can't debug it.

That is why I can't raise any code change/suggestion for this, and if I report the issue, I don't know how to discribe them...

I just checked your changes to build environment and this doesn't make sense to me:

- OPTIMIZER += -Ox # maximum optimization for freebl
+ OPTIMIZER += -O2 # maximum optimization for freebl

With Intel Compiler /Ox and /O2 produce the same level of optimization. Perhaps you wanted to put /O3?

freebl is a part of security module.

I did, I just wanted to say that /Ox and /O2 produce same code with ICC:

/O2 optimize for maximum speed (DEFAULT)
/Ox enable maximum optimizations (same as /O2)

Oh, I thought Ox is the same as ICC's O3 ago ...

Changing Ox to O2 is not too bad ... :)
