Summary: fixits need to be de-duped somehow
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P

I've encountered a problem with clang -fixit: it emits multiple warnings, and
then we apply them in duplicate. This results in:
template <typename T> struct Derived : public Base<T> {
void Work(T x) {
this->this->DoThis(x); // Invalid!
this->this->DoThat(x); // Invalid!
}
};
when given the example on
clang.llvm.org/cxx_compatibility.html#dep_lookup_bases once you add:
void foo() {
Derived<int> d1;
Derived<char> d2;
d1.Work(10);
d2.Work(10);
}
to the bottom. What I would really like to see is clang continue parsing as
though the first fixit was applied, so that we never end up with duplicate
fixits in the first place. That makes the most sense to me and may reduce
diagnostic spam for the user, but I don't know how sensible that is to
implement.
