Greetings! Following up on a request from a GCL user, I've just
committed some minor bugfixes to both branches which enable GCL to
allocate a billion cons elements and higher. The machine in question
has 8Gb physical memory and 60Gb swap, 64bit Itanium, GCL max image
size 32Gb, PAGESIZE 16k.
Here's a somewhat silly test of creating a billion element list:
=============================================================================
>(setq si::*notify-gbc* t l '(nil))
(setq si::*notify-gbc* t l '(nil))
(NIL)
>(si::sgc-on t)
(si::sgc-on t)
T
>(dotimes (i 10) (format t "~S~%" (length l))(room)(setq l (append l l)))
(dotimes (i 10) (format t "~S~%" (length l))(room)(setq l (append l l)))
