Add a test to expose issues with unbounded recursion through `iadd` during egraph rewrites, and bound the recursion of `will_simplify_with_ireduce`. Fixes bytecodealliance#7874 Co-authored-by: Nick Fitzgerald <fitzgen@gmail.com>
…ass (bytecodealliance#7859) * Cranelift: Use a fixpoint loop to compute the best value for each eclass Fixes bytecodealliance#7857 * Remove fixpoint loop early-continue optimization * Add document describing optimization rule invariants * Make select optimizations use subsume * Remove invalid debug assert * Remove now-unused methods * Add commutative adds to cost tests
* Fix a few egraph rules that needed `subsume` There were a few rules that dropped value references from the LHS without using subsume. I think they were probably benign as they produced constant results, but this change is in the spirit of our revised guidelines for egraph rules. * Augment egraph rule guideline 2 to talk about constants
