To use this option, you must also specify /Qipo [v

I think icc has an option to limit pointer size to 32bit.

No, we have -mcmodel as well, but that only specifies the maximum size of the
data and code segments and does not change the size of pointers (-mcmodel=small
is the default btw).

Subject: Re: 32-bit pointers on 64-bit operating systems
The natural analogy would be with MIPS n32 (an ILP32 ABI for 64-bit MIPS
hardware), which also indicates the directory names (/lib32) to use.
There would c

This would be something like Intel's -mcmodel=small, see

Right, a new 32bit ABI would need to be defined with all its problems of
introducing another multilib variant.

environment sets int, lo
