--- Comment #2 from Antonio Di Monaco <antonio.di.monaco at sap dot com> --- Thanks for your feedback. We'll disable split-dwarf option when LTO is enabled, thus making the output consistent. Nevertheless, I agree with your solution, if DWOs make no sense when LTO is enabled, split-dwarf should be disabled automatically when -flto is used. Thanks for your help, BR, Antonio
