:) thanks Philippe. I realized you are a Valgrind developer. I may not be
able to do that implementation. But out of curiosity, if someone does that
for static arrays, I guess he/she should have access to some DWARF3
information that is already decoded by valgrind (I guess). So where should
he/she finds the decoded DWARF3 data structures and related functions in
the valgrind source code? Are they easy to work with? What is the
complexity of that part of valgrind?
