--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The warning started with r12-6677
ipa/103989 - avoid IPA inlining of small functions with -Og
The following change avoids doing IPA inlining of small functions
into functions compiled with -Og - those functions will see almost no
followup scalar cleanups so that the benefit anticipated by the
inliner will not be realized and instead the late diagnostic code
will be confused by dead code that is left around.
