--- Comment #16 from Jeffrey A. Law <law at redhat dot com> ---
reload has traditionally removed subregs of hardregs and passes after reload
have depended on that behaviour. Doing something similar in lra is obviously
necessary. In fact, subregs of multi-word hard regs isn't ever supposed to
appear in the except during allocation & reloading.
I'm not sure why final has another call to cleanup_subreg_operands. While git
blame blames me, I was just refactoring existing code code back in '98.
Does that shed any light on what the right behaviour for LRA ought to be?
