Too late: to see the effects again I should revert the patches and
rebuild without them.

The largest patch I have contains several enhancements for
ColdFire targets made by Peter Barada. I believe he will eventually
push these changes by himself.

Another big patch by Paul Dale adds a flavour of PIC code that
allows executing binaries from romfs without loading the text segment
in memory (XIP). This is just for uClinux, along with some clever GOT
tricks required to support shared libraries in position independent
code.

Most of my work has involved merging these patches and forward-porting
them to gcc 3.3. I've tried them on a recent 3.3 CVS to make sure they
will still apply when 3.3.1 gets out.

Unfortunately, I have no time to mantain another set of patches for
gcc's CVS trunk. Anyway, fixing bugs in these changes will take some
more time.

I've reported the only bug which is likely to affect code already present
in the official tree to Peter Barada. He told me there was already an open
PR for it. I think he's been discussing the issue some days ago on the
gcc ml.

All my other fixes are not appropriate for GCC's bugzilla until Peter and
Paul's patches get in. Some of the patches, such as uClinux's unique way
of implementing shared libraries, are also too controversial to be
submitted.

I've just filed for copyright assignment, so I'll be able to submit my
patches when the time will come.
