--- Comment #6 from Maxim Zaitsev <7aitsev at pm dot me> --- (In reply to Martin Liška from comment #2) > @Maxim: I see -fdump-class-hierarchy[-n] mentioned in PDF manual. Where do > you see -fdump-translation-unit mentioned in GCC 8.x documentation? My apologies. Only `-fdump-class-hierarchy` was present in the docs, but `-fdump-translation-unit` doesn't work too since it was replaced. I thought that the change would be mentioned somewhere in the docs, but it's only my assumption. Thanks for quick response and fixing the issue!
