My patch to allow defining constraints in the machine description rather than with tm.h macros has been on mainline for a week now with no serious problems reported. Now would be a good time to start converting ports. Conversions are easy, but are best done by port maintainers, as careful testing is required. If we all chip in, we ought to be able to get all ports converted in time for 4.2, with the spiffy new things that that enables on track for early 4.3 -- e.g. preprocessing constraints so reload and recog have to do less work at runtime, and autogenerating the 'Machine Constraints' section of the manual.
