-//        call in source order. Writing it after the call (the m2c reading)
-//        pushes the store into the *next* jal's delay slot and makes gcc keep
-//        obj pinned in $s0 across everything -> 91 ins / 21 mismatched.
-//        With the store hoisted above the call, CSE naturally keeps
