ICC has 64bit cross to 32bit compiler/linker?

Hi,

Because building Firefox X86 using icc ipo needs very much memory (32bit linker request more than 4G), I want to know whether intel has the 64bit cross to 32bit tools.

I had tried to use -Qipo100, but it don't effect. Is there any other method to reduce Qipo memory?

Thanks.

If you don't use'-Qipo100' option IPO should be disabled ( a default value is'OFF' ).

This is what 'Intel C++ Compiler User and Reference Guides' say.

The IA32 compilers run native in a 64-bit OS. That's an entirely viable way to develop. Of course, the 32-bit compiler is still limited to 4GB address space, where in practice it is limited to less than that when running on a 32-bit OS.
The compiler manuals discuss in detail ways to partition IPO.

But I want to use ipo.

Thanks.
It seems my origin method is right.
When I change -Qipo128 to -Qipo256, it works.
