Subject: mark_stack () vs GCPROn
Date: Thu, 6 Dec 2012 01:00:59 -0800 (PST) [thread overview]
Message-ID: <1354784459583-271770.post@n5.nabble.com> (raw)
Hello,
Emacs has a `mark_stack' function in alloc.c, which looks for (potential)
Lisp_Objects located on the current C stack. Does it mean that GCPROn
mechanism is not necessary for local Lisp_Object variables now ? It is
quite clear that gcprolist is still necessary for static Lisp_Objects.
What are the relationships between these 2 approaches for marking objects ?
My impression is that mark_stack() was introduced after the GCPRO thing and
partially superseded it, though I feel that I may be overlooking something.
Best regards,
Sergey Mozgovoy.
