The frontend still outputs GENERIC, but at useless you have unlowered gimple already (also known as 'tuples' these days). This was true before, just that gimple was a subset of GENERIC, even from a data-structure point of view. The GIMPLE of today is accessible via gimple_body (). Richard. > Brad > > >
