+ function.
+
+ The macro actually mentioned the input registers first,
+ because they get renumbered into the output registers once
+ we know really do have a leaf function.
+
+ To be more precise, this register allocation order is used
+ when %o7 is found to not be clobbered right before register
+ allocation. Normally, the reason %o7 would be clobbered is
+ due to a call which could not be transformed into a sibling
+ call.
+
+ As a consequence, it is possible to use the leaf register
+ allocation order and not end up with a leaf function. We will
+ not get suboptimal register allocation in that case because by
+ definition of being potentially leaf, there were no function
+ calls. Therefore, allocation order within the local register
+ window is not critical like it is when we do have function calls. */
