Subject: Question about pure space
Date: Thu, 18 Apr 2024 17:01:24 +0200 [thread overview]
Message-ID: <m2le5ag1ff.fsf@Pro.fritz.box> (raw)
I'm trying to understand pure space better for the scratch/igc branch.
From my flimsy recollection, there is a pure[] array in which Lisp
objects can be stored. That array still seems to exist, and it is quite
large on macOS, ca. 6Mb.
The odd thing is that I can't find where it is used. The function
pure_alloc always uses purebeg, which is initialized to NULL, and then
gets malloc'd.
What the heck?
Is pure[] used at all?
If yes, how?
(If not, why is it there?)
