* altos/lisp: Use poly stashes for stacksKeith Packard2017-02-20
| | | | | | Saves some memory. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Change GC to do moves in batches of 32Keith Packard2017-02-20
| | | | | | This should make it quite a bit faster than doing one at a time. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: add length, pack, unpack and flushKeith Packard2017-02-20

* altos/lisp: more GC issues. add patomKeith Packard2017-02-20
| | | | | | | Use global ao_lisp_stack instead of local stack so that gc moves of that item work. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Change lisp objects to use ao_poly everywhere. Add constKeith Packard2017-02-20
| | | | | | | | | | | This makes all lisp objects use 16-bit ints for references so we can hold more stuff in small amounts of memory. Also adds a separate constant pool of lisp objects for builtins, initial atoms and constant lisp code. Now builds (and runs!) on the nucleo-32 boards. Signed-off-by: Keith Packard <keithp@keithp.com>
