After a few evenings of serious hacking, I've integrated precise heap
scanning
into the GC.
Awesome! Thank you so much for doing this. Does the GC have knowledge of
pointers on both the stack as well as the heap?
3. new only takes RTTI. It is not a template. Unless RTTI gets bitmasks
in
the format I created (which I'll document once I clean things up and
release,
but has only deviated slightly from what I had talked about here), stuff
allocated using it won't be able to take advantage of precise heap
scanning.
The default bitmask, if none is provided, uses good (bad) old-fashioned
conservative scanning unless the entire block has no pointers, in which
case
it isn't scanned. This means that we have all the more incentive to
replace
new with a template of some kind.
I'm surprised nobody commented on this. Andrei said Walter decided that new
shouldn't be a template. But it seems like a good idea to me. Templated
new has received positive feedback from the community, and here is another
advantage of templated new.
