[LLVMdev] StructRetPromotion and linkage

[Matthijs Kooijman]

Hi all,

I was looking at the StructRetPromotion pass this morning and noticed it
doesn't look at a function's linkage at all. Since it changes the signature of
the function, I would say it should only change internal functions, like
ArgumentPromotion does for example.

Is there some implicit check I'm missing, or should an explicit check really
be added?

Gr.

Matthijs
