I don't want to have these symbols not mangled (they need indeed be
mangled and randomized), the problem is that the randomness is sometimes
not enough. See PR 9393 for a case that would have been solved with

This point has been discussed in a number of PRs already. I maintain
my position that gcc could invoke the as-if rule to give these functions
internal linkage if they aren't taken as template parameters. Since

It is not exactly a G++ choice. This is what the ISO/ANSI C++ International
Standard mandates. I suggest you to post a mail to the newsgroup
comp.lang.c++.moderated or to comp.std.c++ to enquire an explanat

i understand your point of view though i'm not happy with g++ behaviour. A
function with external linkage that can't be called seems like an oxymoron to
me. This makes my library very big. i had to mark a lot of

GCC is not allowed to remove the definition of a function with external
linkage. The fact that nobody will be able to call it because it is in an
anonymous namespace it is irrelevant.

of course. but if they are not ? they should be optimize, no ?
if g++ inlines three(), why does it remove three() global definition if it's
never used ?

Names declared in anonymous namespaces do not get internal linkage by default.
In fact, they can be used as template non-type arguments (names with internal
linkage cannot be used in such contexts).

The main reason IIRC for this is because C++ and export templates (even though we
don't implement
export yet).
