Which shows that I need to merge the IRA and reload/lra passes. Honza tells me that they are considered "separate" has historical reasons only. Given that reload pushes TV_IRA and that the boundary isn't GC safe I don't think that is too bad (dump files will now be shared, of course). I'll schedule a gcac checking bootstrap over night as well. Richard.
