Is the change back portable there too? There are some issues previous to GCC 14. It requires the new lazy_ssa_cache from GCC 14, which is dependent on some other changes in range storage allocators. I did convert the new cache code and isolated it all to the new assume pass file, tree-assume.cc. This should, in theory, not impact any other part of the compiler. I've attached the patch. I will also submit it, although I debated not doing so. I will leave it up to the release managers whether they want this added to GCC 13 or not. Feel free to use it on your own compiler however, it *should* work :-)
