You should be using "=b" to designate the operand as *output* only. Otherwise, reload will attempt (unsuccessfully) to load up "scratch:SI" as input value ... B.t.w. if the register class denoted by "b" has just a single element, you might just as well use the hard reg directly in the insn pattern here.
