Hi Guys,
I am applying the patch below to fix a minor discrepancy in the rx.md
file. Several patterns can only use restricted memory addresses.
They have the correct Q constraint, but they were using the more
permissive memory_operand predicate. The patch fixes these patterns
by replacing memory_operand with rx_restricted_mem_operand.
Cheers
Nick
