[LLVMdev] linker_private* linkage

[Nuno Lopes]

Hi,

I'm trying to understand better how linker_private (and friends) work.
 From what I can understand from the manual  
(http://llvm.org/docs/LangRef.html#linkage_linker_private), it seems  
that a linker_private function cannot be removed by the optimizers.  
Only the linker can discard the symbol. However, I tested with 'opt  
-O1' and a function with *no users* is removed. Same thing happens  
with the other linker_private_* linkage types.

Is my reading of the documentation correct (i.e., is this a bug in LLVM)?

Thanks,
Nuno
