I'm publishing some minor changes to Whirlwind and the Vortex runtime
system.
*) I got towers w/ the 1.2.1 SDK to compile w/ optimization. It only
took about 6 hours. :) I had to fix a small problem with lowering in
order to make it verify itself properly.
*) I extended the object size histogram primitive in Vortex to also
track the number and size of objects per referring class. This way
you can tell a little about which kinds of objects contain references
to objects, to better identify space leaks and the like. (Try
app.new_checkpoint.object_size_histogram to see what all is in the
checkpoint.) Note that an object can be referenced multiple times,
and the primitive currently accumulates per-referring-map space
redundantly for each reference, not for each target object. The
totals are still per target object, so you can tell how much space is
really being taken up, vs. how many references to that space are from
different kinds of sources.
There seems to be a problem w/ the Vortex makefiles that I don't
understand. After I changed one of the runtime system's header files,
it should have forced recompilation of all *.cecil.o files, but it
didn't. So I had to manually remove all the *.cecil.o files, and then
recompile from scratch. You may have to do the same.
