From 206b5b2661be37efdff3c6aedb6f248c4636be79 Mon Sep 17 00:00:00 2001 From: Stephan Bergmann Date: Sat, 15 Sep 2018 19:13:19 +0200 Subject: New loplugin:external ...warning about (for now only) functions and variables with external linkage that likely don't need it. The problems with moving entities into unnamed namespacs and breaking ADL (as alluded to in comments in compilerplugins/clang/external.cxx) are illustrated by the fact that while struct S1 { int f() { return 0; } }; int f(S1 s) { return s.f(); } namespace N { struct S2: S1 { int f() { return 1; } }; int f(S2 s) { return s.f(); } } int main() { return f(N::S2()); } returns 1, both moving just the struct S2 into an nunnamed namespace, struct S1 { int f() { return 0; } }; int f(S1 s) { return s.f(); } namespace N { namespace { struct S2: S1 { int f() { return 1; } }; } int f(S2 s) { return s.f(); } } int main() { return f(N::S2()); } as well as moving just the function f overload into an unnamed namespace, struct S1 { int f() { return 0; } }; int f(S1 s) { return s.f(); } namespace N { struct S2: S1 { int f() { return 1; } }; namespace { int f(S2 s) { return s.f(); } } } int main() { return f(N::S2()); } would each change the program to return 0 instead.
