Incorporation of Objective-C 2.0 changes into GCC trunk

Incorporation of Objective-C 2.0 changes into GCC trunk

[Gregory Casamento]

All,

Hey guys.... I'm wondering if there's a timeline for incorporating the
Objective-C 2.0 changes from Apple into the trunk of GCC.

If not, I would like to know what the GNUstep project can do to help
make this happen.

Thanks very much. :)

Sincerely, GC

No.  But you just have to take patches from Apple's GCC, polish them and
send them.

Do Apple's changes rely on the NeXT runtime?  If not, the job would be
easier.

As far as I'm aware apple has an assignment for changes to gcc, so it
should be possible to pull them in.

You're not forced to assign changes that you do not want to assign.

I don't understand.  Yes you are forced to assign copyright to the FSF
for changes you contribute to FSF GCC.  You are of course not forced
to do this for your own forks of GCC.

Yeah, if Apple didn't send the code to FSF GCC, the fact that Apple has 
an assignment does not count.  They're not forced to assign changes that 
they do not want to assign -- as long as they keep the changes local, 
which they did for Objective C 2.0.  The only way to know, would be to 
ask someone at Apple.

  Persuade Apple to de-embargo their engineers from showing their faces in
public round here?(*)

  At least from the outside, it appears that Apple(**) is simply not
interested in contributing to GCC.

    cheers,

If someone is seriously interested in merging pieces of the Apple GCC  
tree into the main FSF tree, and if there is a process in place to  
make the assignment happy, I would be happy to try to make it happen.

The major caveats are that the Apple GCC tree isn't in great shape (it  
will take some work to make the objc2 changes "submission quality"  
because they may break the gnu runtime, be overly darwin specific,  
etc), Apple engineers will not be able to help with this work, and it  
may take some time to get the approval to assign copyright of the code.

What is the process for getting a blob of code assigned to the FSF  
that is not just being committed into the tree?

Creating a branch on gcc.gnu.org and committing it there should be enough.
