   Please provide more information, such as the list of reload for the insn.
There could be a number of reasons for a reload failure, some more obvious
than others. The least obvious one I've come across (just a few days ago) is
an unfortunate specification of CLASS_MAX_NREGS(), causing reloads to be
sorted in the wrong order (see reload_reg_class_lower() in reload.c),
thereby exhausting a small register class.
