When reload looks at the above pattern, it will see just two operands, both of which are output-only. So when it decides to reload one of the operands, it will only provide an output reload, no input reload. For operands that are actually used for both input and output, you need to provide two match_operand clauses, and tie them using a matching constraint. Simply using match_dup doesn't accomplish that.
I should have seen that. Perfect explanation. It works as expected now, thanks.
