Having an architecture in make universe isn't about making the code work, it's
about encouraging the code to remain compilable even though most developers
don't actually work with the architecture. Sun4v is arguably our most
edge-case architecture right now, but given that it shares a lot of code with
sparc64 and sparc64 is run by a non-trivial number of people (more than arm?),
keeping it compiling hasn't proven very difficult. And recent universe
breakage has often-as-not been in i386 and amd64, not sun4v.
Is there something in your recent work that prevents sun4v from compiling and
hence justifies disabling it entirely, and hence guaranteeing it won't compile
in the future because it falls off the "make it compile" radar? If so, then a
policy decision to drop sun4v support may be called for -- but this is
something to discuss with the people who added support for the architecture,
the release engineering team, etc, and not to make unilaterally.
