[swift-dev] Marking a function as __attribute__((weak))

[Philippe Hausler]

Is there a way to mark a function in swift (on Linux) to use the same emission strategy as weak declarations in c? 

I was to tinkering with some ideas on fixing some poor behavior in swift-corelibs-foundation and weak would potentially solve this specific case.

For reference this is the syntax I am interested in (since it is a bit obscure) https://en.m.wikipedia.org/wiki/Weak_symbol
