--- Comment #91 from Richard Biener <rguenth at gcc dot gnu.org> --- So the other simple idea I have is to limit the number of active store groups and force-terminate in either a LRU or FIFO manner. For the testcase at hand the decls we start the chain for are all only used in full but knowing that would require some pre-analysis of the IL similar to what SRA does for example (collecting all accesses). It's then also still easy to "break" such heuristic so limiting is in the end the only (and I guess best) option.
