Richard, I suppose you mean the problem is in this define_insn:

(define_insn "*thumb1_ashlsi3"
  [(set (match_operand:SI 0 "register_operand" "=l,l")
        (ashift:SI (match_operand:SI 1 "register_operand" "l,0")
                   (match_operand:SI 2 "nonmemory_operand" "N,l")))]
  "TARGET_THUMB1"
  "lsl\\t%0, %1, %2"
  [(set_attr "length" "2")
   (set_attr "conds" "set")])

which should set "length" depending on the operands?

(BTW when should ARM_LSL_NAME be used instead of "lsl"? Or is ARM_LSL_NAME not relevant for Thumb?)
