As a developer, what I would generally prefer is

-O0 fast compile, completely debuggable
-O1 slower compile, better code


We might consider:
-O1 slower compiler, better code, completely debuggable

or perhaps "completely debuggable on targets that use
dwarf2 and once the needed debugging improvements (such
as split register ranges) have been implemented" ...
