I think it would be easier to fix scheduling to properly detect the must-conflicts by noting down the stack slot partition used in MEMs (and obviously if we end up having MEMs w/o an assigned parition make that conflict with any other - this can then be refined with PTA information from the alias export). The same is true for gcse-sm - any other RTL pass that may be a problem? Richard. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39604
