OK, so you are agreeing that good debuggability is impossible
with all the optimizations in place, so once again, let's have
an optimziation level that optimizes as far as possible without
harming debuggability.


I don't oppose such an optimization level, even though I don't know
that we agree on what "good debuggability" stands for.


My definition is that it should be indistinguishable from -O0
except that I could live without being able to modify variables.


It's just that changing optimizations is precisely *against* the goals
of my current project.  So, don't expect significant efforts to this
end from me at this time.

But you can't achieve the above criterion with your approach.
