[LLVMdev] extending the LLVM assembler: more than one linkage "type"?

On our target, we want to add a new linkage type "attribute" (or 
something similar), orthogonal to the linkage types used. However, I see 
that only _one_ linkage type can be specified for each function (despite 
the composite nature of some of the existing linkage types).

Should I duplicate all linkage types that we use (for example, like weak 
and linkonce are duplicated into weak_odr and linkonce_odr), or are 
there some other option?

In more detail: We have a frontend pragma that controls if calls for a 
given function declaration should be absolute, instead of PC-relative 
(which is the default). This affects some aspects of the linkage 
process. How should the LLVM assembler be extended to pass this information?
