We would= be able to detect this if https://dwarfstd.org/issues/221105.1.html were implemented. As mentioned in the DWARF issue, this would also other languag= es and may even simplify some work that debuggers need to do. Since it is just= an ignorable attribute, can we start supporting it even before it is standardi= zed.=
