The bug has been introduced when changing the warning system to do
more in the front end. The problem is that for:
module m
contains
function f()
end
end
the sym->attr.referenced gets set - and no warning is printed. I now
ignore the sym->attr.referenced attribute as the RESULT == NULL_TREE
should only be reached if the variable has not been assigned a value.
Additionally, I now only set TREE_NO_WARNING() if a warning has been
printed; that way, some other useful middle-end warnings might be
still printed. I have to set the NO_WARNING also for sym !=
sym->result as it otherwise prints a middle end warning into addition
to the FE warning. But the FE warning has been printed already before
for the result variable.
Build and regtested on x86-64-linux.
OK for the trunk? How far should this be backported - all the way down
to 4.4?
