are current fixes for 48 bits sufficient to later extend it to 52
bits? It would be good if userland can already support 52 bits to
avoid fixing it again.
Well, just to muddy the waters a bit. Its possible there will be further
problems with 52-bit VA's. Its hard to predict what other latent
applications are using tagged pointers in bits that aren't affected by
the 48bit VA. Plus, the js 1.85 changes just bump the tags a little
higher. So anything still using 1.85 with 52-bit VA's will have
problems. That is part of the reason why i'm trying to move everything
that is still on js185 to mozjs24/38.
