I did, at least superficially. The GCC 10 series does increase the
image sizes a bit (say, around 200 kiB on a 6.4 MiB ath79/74Kc image),
due to the new inliner heuristics. However, the GCC 11 series seems to
further tune the inliner, and the images are again smaller (still a
little bigger than with GCC 9).
