and finally, interactivity &hexplorer
the new jump list allows you to quickly find global variables, stack frames, or instances of a given type.
you can now follow pointers by clicking their values.
and, among other things, the new inspector shows you the incoming and outgoing pointers for the selected object.

drawing the memory map from yesterday! &hexplorer
as i scroll through memory, we first see some global variables (including the malloc state).
those are followed by the stack (the cyan/green/brown bands are stack frames; the stack is quite a bit larger, i'm current not drawing zero bytes).
and at the end, there's the heap. where we can see a linked List (created by the demo program).

mapped out memory using debug info. &hexplorer
i spent quite a while figuring out how to deal with aliasing.
turns out, my test program (almost) doesn't have any aliasing 😄

edit: yeah, no, of course it does. silly little bug.
for anyone interested, i build the mapping in two passes.
first, i collect all unique (ptr, type) pairs by following pointers depth first. (this uses a visited set, which caught the aliasing)
then i sort those by decreasing type size and create the mapping.
sorting makes sure i create mappings for structs before processing pointers to their fields (roughly). which is useful for storing "reverse pointers".
