Do not eagerly merge equivalence classes with the same constant value. Reason: - when we split a value slice, the subslice might already exist in the egraph and already have subslices itself, which breaks assumptions in split/split_core. - introduces unnecessary splits Now: - wrap constants into fresh function symbol before creating the enode - check value compatibility in on_merge callback instead - track pointer to value_node for each enode, and update it in on_merge |
