--- Comment #22 from Roger Sayle <roger at nextmovesoftware dot com> ---
This issue is related to PR 100378, which is another combine-related
regression.
In fact, PR 100378 is resolved by the (now disapproved) patch in comment #8.
Presumably a variant of Richard Sandiford's make_compound_operation fix sho=
uld
be able to handle PR100378 too.  Resolving multiple (long-standing) regress=
ions
really should be suitable for stage 4.=
