Thanks for the help everyone.
I would like to begin working on this (== supporting this natively in
the compiler with a keyword/modifier (not sure about the correct term
:))).
What steps do I need to take before beginning in order to ensure this
effort will go into the main branch once it's comple

Seems like a strange assumption. If the application can use 32GB
what stops it from using 40GB or 64GB? Systems with that much
memory are readily available these days.

The application does go well beyond the 4GB range.
By using this implementation I can use 32-bit pointers for most
objects (those that do not require <8byte alignment, i.e. chars, etc.)
while still have a 32GB address range.

Hi,
I hope I'm not flooding with this topic. I've did some research and
couldn't find anything relevant on this topic.
My team is developing a large scale CAD application that has a large
memory footprint, requiring strong machines to run.
The application uses pointers mass
