For the moment I made [1] somewhat-pruned mem2reg pass, not even sure how to call it. But it indeed required to compute dominance frontiers.

Why not fully maximal SSA + DCE? I mean, other than timings consideration. Fully maximal does not even need any graph traversal, it is entirely local to each block.

While it is neat, it's premature optimization IMHO. Fully maximal SSA (at the entry of each block insert a phi-node for each variable) + dead code elimination (we need it anyways) is much simpler.
