--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
With an even more slightly enhanced patch for PR79345 we can warn here even
with -fno-tree-sra, but at -O2 we run into the issue that PRE inserts loads w/o
location (and the patch doesn't warn for loads that do not have a location...).
