altos/lisp: Move stack recursion check after null check

2016-11-19T07:37:44+00:00

Don't crash when printing null stack this way. Signed-off-by: Keith Packard

altos/lisp: Cleanup some DBG defines

2016-11-19T06:53:36+00:00

Get rid of the remaining duplicate defines. Signed-off-by: Keith Packard

altos/lisp: Share binary search for memory chunk between mark and move

2016-11-19T06:52:53+00:00

Save some text space. Signed-off-by: Keith Packard

altos/lisp: Add builtin 'collect'

2016-11-19T06:52:10+00:00

Collect memory, return amount free. Signed-off-by: Keith Packard

altos/lisp: Sort frames by atom

2016-11-19T06:43:28+00:00

Fortunately, the collector always retains the relative order between addresses, so we can sort based on the atom address itself. This reduces the time spent looking for names in larger (e.g. global) frames. Signed-off-by: Keith Packard

altos/lisp: bounds check in move_map plus binary search

2016-11-19T05:16:11+00:00

This makes move_map faster by skipping all addresses which aren't changing. Also changed the interface from address to offset to avoid computing the offset multiple times. Signed-off-by: Keith Packard

altos/lisp: Empty lambda body is not an error

2016-11-19T05:15:33+00:00

It's not very exciting, but it's still legal Signed-off-by: Keith Packard

altos/lisp: Use poly stashes for stacks

2016-11-19T05:14:47+00:00

Saves some memory. Signed-off-by: Keith Packard

altos/lisp: Make DBG settings global

2016-11-19T05:12:50+00:00

This avoids having different values in different files, which wasn't useful. Signed-off-by: Keith Packard

altos/lisp: Add continuations

2016-11-19T03:04:05+00:00

This provides call/cc and makes 'stacks' visible to the application. Signed-off-by: Keith Packard
