[uml-devel] Using -fcombine for UML

[uml-devel] Using -fcombine for UML

[Paolo Giarrusso]

Look there, it would be very useful IMHO for UML:

http://lkml.org/lkml/2006/8/24/212

But I will not have the time for the UML changes, so tune in for them.

Yeah, looks interesting, but a bunch of work.  When you build a directory
at a time, everything that is exposed to the outside needs to be declared
__global.

This is useful documentation in its own right, but it will take some time
to do.

I was thinking by thematic areas - for instance each _user with its _kern 
(there are still some such examples). Having little wrappers inlined 
(especially for some ones in the hot paths, I'm recalling something about mm 
fault handling or such) would help however, and could be prioritized.

That's an interesting idea.  However, I'm trying to get rid of the
_user/_kern pairs, and have mostly succeeded by now.  We would have to
pair up files in different directories.
