DECL_IGNORED_P means completely ignored for debug info purposes though and I think that the Ada compiler expects this semantic. > This patch improves the debug experience at least a bit by emitting > at the line number information where the thunk has been defined. > I do not dare to touch anything but dwarf2 debug info, therefore > the patch is a bit awkward. Please run the GDB testsuite with Ada support on the patch. -- Eric Botcazou
