No. It wouldn’t for a number of reasons. First, you can often mix hard-float and soft-float libraries with no ill effect tot he upgrade process (though not always). Second, I’ve implemented code in the run time linker to link in the correct hard vs soft libraries. Third, I’ve implemented a libsoft that’s like lib32 so you can run both types of binaries on the same system, if you need to for some reason. In fact, its so that the upgrade process results in better behavior that I’ve gone down this path. I have a few loose ends still to tidy up on this, but haven’t had the time to push it through to completion.
