And this is why there seemed to be consensus to merge the two in the middle-end and preserve debug-info somehow differently. Like with a "frontend type-id" on the decl. That would allow lowering of f.i. integral types to their modes at some point, too.
It seems a clear mistake to me to tie debug information so closely to the actual gcc type information, and this is another example of it causing unnecessary trouble.
