The new target-independant implementation of fold-mem-offsets pass can
be found in the list (link is
https://gcc.gnu.org/pipermail/gcc-patches/2023-June/621920.html)
Aside from now being target independent, I have fixed a number of new
bugs that emerged when running this on other targets and a min

I remember I was getting better improvements in the past, but most of
the cases had to do with the sta
