Re: Listing file-scope variables inside a pass

Thanks.
Where exactly should I be looking?
cgraph.c, cgraphunit.c, cgraph.h
see cgraph_varpool_nodes, FOR_EACH_STATIC_VARIABLE (static here means
having scope greater than a single function, it does not mean "all
variables declared static in C")
Will the cgraph nodes also have global declarations that are never
used inside any
function .
If you ask for all of them, it will give you all of them
If you ask for only the needed ones, it will give you all of the
needed ones (see FOR_EACH_STATIC_VARIABLE)
