Hi everyone,
So it looks like this new warning has appeared as part of the data flow
analysis of -O4. The thing is, I personally have a problem with this
being a warning, because there's nothing inherently wrong with not
covering every case branch or omitting an else block (especially if one
isn't needed). Adding "else ;" everywhere seems to just cause bloat.
Still, code style aside, can I suggest the warning be downgraded into a
hint? Warnings should indicate the possibility of unstable code due to
uninitialised values, for example, and DFA should be able to detect that
anyway as a separate warning (e.g. if a case block doesn't initialise an
output value in all of its branches).
