There are quite a few PRs about -fssa, so apparently people use it even if it's not supported. So just disabling is maybe not such a great idea. What is the long-term plan for RTL-SSA? Last time I read the rtlopt web page, it said that Honza had been working on MidRTL. What's the plan for that now? Even with the tree-SSA branch merged, there are still cases where RTL-SSA could be useful. But if the plan is to kill it altogether, maybe it could be deprecate the feature for 3.4 (assuming the tree-SSA will succeed and be merged before "3.5")?? Greetz Steven
