No, it doesn't. It simply converts to GIMPLE. Once you inserted the new statement, you will need to call mark_symbols_for_renaming() on the new statement. Unfortunately, this is all not well documented. The canonical way is: - create the statement with build() or force_gimple_operand() (if you want to gimplify an expression). - insert it on an edge or block with bsi_insert_... - Call update_stmt() to have it scanned for operands. - Call mark_symbols_for_renaming() to find all the new symbols and mark them for renaming. I keep promising myself that I will spend a few weeks writing up API documentation for all of this. The contents of tree-ssa.texi are too out of date. One dragon at a time...
