Some optimizations can be stronger if compiler give up ability to generate
at least approximately usefull debug information for optimized programs.
These transformation are not done when @option{-g} switch is not specified,
as politics is to get the code with @option{-g} and without equivalent,
except for debugging section.
This optimization enables such transformations. It is still compatible with
@option{-g}, but debugging resulting programs will be even higher challenge.
