Hi Simon,
I'm wondering why in the GC we don't short out IND_STATICs like we do in INDs
and BLACKHOLEs. Is there a reason for that? In this code in evacuate():
case IND_STATIC:
evacuate_static_object(IND_STATIC_LINK((StgClosure *)q), q);
return;
Why not do something like
case IND_STATIC:
q = ((StgIndStatic*)q)->indirectee;
*p = q;
goto loop;
I actually tried it and it broke a lot of things, but I don't understand why.
We basically turn this
heap closure -> IND_STATIC -> heap closure
into
heap closure -> heap closure
To me this should work, but for some reason it doesn't. Could you comment on why
this doesn't work?
Thanks,
Ömer
