Yes.
That's exactly from where I have took the code for the tree level split_edge.
A question:
what do you think about extending the basic block iterator (bsi) to handle
a union {tree, rtl}, then use iterators instead of rtx-es in functions like
split_block (basic_block, rtx) ?
The implementation (ie. tree_split_block and rtl_split_block) will decide
wheter the iterator contains a tree or an rtx (C poor man's polymorphism).
