- * Calls a user function for every basic block in the instruction stream.
- *
- * Basic block analysis is pretty easy in our IR thanks to the lack of
- * unstructured control flow.  We've got:
- *
- * ir_loop (for () {}, while () {}, do {} while ())
- * ir_loop_jump (
- * ir_if () {}
- * ir_return
- * ir_call()
- *
- * Note that the basic blocks returned by this don't encompass all
- * operations performed by the program -- for example, if conditions
- * don't get returned, nor do the assignments that will be generated
- * for ir_call parameters.
