There is code in cgraph_copy_node_for_versioning that redirect callers in the list to new location. Since clonning might render some code unreachable and remove edges, this can lead to ICE. But since this was formely invented for IPA-CP, that is now using virtual clones, perhaps we can simply drop this functionality unless you need it in your branch?
I need nothing complicated from cgraph. An exact duplicate of the original function is perfect. After getting that duplicate, I'll walk through it and make some localized code changes which are just a tad more complicated than simple symbol substitution. After optimization is where the bulk (but not all) of the changes for TM are applied. I guess I'll poke at cleaning this up today. I've got to familiarize myself with how virtual clones work... r~
