RFC: Add an "interposible" linkage type (and implement -fsemantic-interposition)
Hi everyone,
Clang/LLVM's support for ELF interposition is in a confusing state, and I propose making a few (hopefully simple) adjustments in order to bring our model into a self-consistent state.
The problem: On ELF systems, global symbols can be interposed. This means, for example, that calls to global functions in some (shared) library defined in that same library might end up being

I think that all makes sense. You're just adding the missing non-ODR
conterpart of 'external' linkage. I could imagine having "external /
external_odr" linkage for example.
That said, do you think we should take the opportunity to split out a bit
for interposability so that we can kill off the *_odr linkage variants?
Today's non-ODR weak functions would look more like

You present a good case for not using "protected" visibility in ELF,
despite it being exactly what it is supposed to mean.
>From what http://www.airs.com/blog/archives/307 says, it sounds like the
*correctness* issue with protected visibility is because LLVM is doing it
wrong -- not an intrinsic property of protected visibility in ELF, or even
ELF/x86. The blog says that the compiler
