Might be worth trying doing some tests where every additional node causes a realloc to try and confirm that you've got all the possible release after free paths

Comment on attachment 185127 [details] the patch Could you remove DFG::Allocator::free ? Also wonder if we should make DFG::Allocator require T have a member that shows we know it's safe w.r.t DFG::Allocator, but that's not necessary for this patch.

Also wonder if we should make DFG::Allocator require T have a member that shows we know it's safe w.r.t DFG::Allocator, but that's not necessary for this patch. I was keeping free() because I want to use it in my next patch. I mean, if we're super crazy about not introducing dead code then I should also remove all of the free list logic. I can do it, but I'd rather be able to use Allocator without further changes for the next stuff I want to do (refactor phi building).

But my plan is to only call free() on nodes that have zero ref count, and that are already Phantoms or Nops, and are being removed from their basic blocks. That should be safe. And of course there may be paths that somehow stash Node* (previously, NodeIndex) to nodes that have zero ref count and are Phantom or Nop. But hey, this is the fun of software. You can always get it wrong.
