The proposal looks fine. I have another question.

What problems exist with cross compiling.

We are still using the cross-compiler for all of our building & testing.
We use:
	gcc version 2.96-ia64-000717 snap 001117 (plus some patches that Ralf added last Dec).


I know that at some point we need to convert to native builds but right now we
dont have sufficient bigsur/lion boxes to do that.

We have not seen any problems with the compiler we are using - at least we 
have not attributed a problem to the compiler.

Should we upgrade to gcc3.0 yet???


Any info on this subject would be appreciated......

The changes to the copy_user pipeline code in the latest 2.4.7-ia64
patch break snap 001117 in some circumstances.  There are workarounds
but they require changes to code that is not IA64 related, not
satisfactory.

I have not succeeded building a cross compiler ix86 to ia64 for gcc
3.0, using a current CVS tree.  The flow insn code breaks on some type
conversions in cross compile mode, even when using gcc 3.0 as the base
compiler.  Debugging is still in progress.

Probably not yet. I would stick to gcc-2.96 based on what you can find
in Red Hat's (or one of the other distributions') ia64 SRPMS.
