Description Martin Nowak 2015-04-20 14:13:55 UTC

We should emit mutable data that can't alias GC memory to a separate .noptr section, so that it can be excluded when scanning GC roots.

Comment 1 Martin Nowak 2015-09-06 20:53:14 UTC

Might make more sense to add a special ptrdata section, so that the GC only has to scan that.

Comment 2 Martin Nowak 2015-09-07 15:44:19 UTC

Something along this line from Rainer.
