I'm sure you can't mean "user-visible semantics were changed, but since
the old ones weren't documented, the new don't need documenting now".
Would you open a PR on this, please, if you don't intend to fix the

BTW, I see this in invoke.texi:

  @opindex d

  @var{letters}.    This is used for debugging the RTL-based passes of the

  pass number and a word to the @var{dumpname}.  @var{dumpname} is generated
  from the name of the output file, if explicitly specified and it is not
