Hi Matthew -- How about this instead?

+@item -mload-store-pairs
+@itemx -mno-load-store-pairs
+@opindex mload-store-pairs
+@opindex mno-load-store-pairs
+Enable (disable) an optimization that pairs consecutive load or store
+instructions to enable load/store bonding.  This option is enabled by
+default but only takes effect when the selected architecture is known
+to support bonding.
