- May 15, 2026 SSA Construction and the Cost of Phi Placement Dominance frontiers decide where phi nodes belong, minimal SSA places too many of them, and pruning by liveness is what keeps the form small enough to optimize. compilers
- Sep 25, 2025 Escape Analysis and Scalar Replacement of Aggregates Escape analysis decides which allocations never leave a thread or a method, and scalar replacement turns those objects into SSA values so the allocation and its fields disappear entirely. compilers
- Jun 17, 2025 Constant Propagation over a Flat Lattice Propagating constants requires a lattice with an explicit top element for "not constant", a meet that never guesses, and an SSA-based solver that avoids the quadratic worklist. compilers
