Geert,
possibly, we can configure the compiler to report/warn on any stack
usage from every invocation and then turn all those warnings into a
readable format or some format that further visualization and analysis
tools can process.
If that works, we can remove the checkstack tool. It is not a
massively large script, but it is certainly written with a very
special purpose. I mean it basically does object-code
reverse-engineering with a magic set of regular expressions in Perl.
If our current compilers can emit the same information, we are
probably better off just using the output from a compiler and
postprocessing that.
Anyways, I think it is worth investigating all that and then see if
the checkstack.pl tool still has a unique functionality, or if there
are other better ways to get this kind of information---well, it is
marked as todo, so anyone is free to pick it up.
