I think this is ok for now, especially if the support will eventually be removed because the linker will support external functions as noted in your TODO (note in order to do this in the index you would need to set up the flag during the compile step, not the linker invocation as you are doing here, which has some advantages if this will persist longer term). I have a suggestion about the error detection below, so that you can report errors earlier along with the failure reason. ================ Comment at: llvm/lib/Transforms/IPO/FunctionImport.cpp:496 dbgs() << "ignored! No qualifying callee with summary found.\n"); continue; } ---------------- Probably better to issue an error here with the import failure reason?
