Assuming you're referring to cgen model files as opposed to cgen scheme
sources, such port maintainers can work this out amongst themselves.
I see no need for formal process to handle this (hypothetical?) problem.

Then as soon as the breakage is identified, the person causing the
breakage will have to negotiate to assure some sort of correction.
No big deal.

In line with dje's hints, I have no objection, as long as people
stand behind their patch if unforseen negative effects result.

[Just to be clear, the context of my remarks is changes to .cpu/.opc files.
Nothing else.]
A port maintainer is a port maintainer.
If redhat is the port maintainer for xstormy16 and checks in something to
xstormy16.cpu because they need to change binutils and later find out
they've broken gdb(sim) it's a problem of their own doing. They can undo it.
Similarily for any port maintainer.

I don't understand. The context here is .opc. files.
Changes to .opc files don't affect sid or gdb. Only binutils.

I'm not sure I would word it that way. Maybe it's ok, I dunno.
uber-hackers in binutils/gdb may be able to make port specific
changes as they deem necessary (are they?). I'm not sure this should extend
to .cpu files. But I certainly have no problem with authorized
port maintainers of binutils/gdb making changes to cgen port-specific
files (provided of course they're willing to work through any problems
that may arise).
Given the above seemingly misunderstandings, just so we're clear,
"port-specific changes" means changes to files in src/cgen/cpu
[or whereever they move to].

[flipping the pedantic bit]
Ok, gdb uses the disassembler.
Still, if src/opcodes is ok for binutils, I don't think
it's a problem for gdb or sid.
And if it is, the problem can be dealt with as it arises.

This would only all make sense if the .opc et.al. files were all (C)
FSF. Which is back to my things-to-do-today list of fill out the
src/cpu directory a little.

Sorry, I don't see how that relates to the issue. Regardless of whose
(C) is on the files, the current matter is which of several potential
maintainer types should feel free to commit changes.
