+This is a rewriting of the OE patch of the same name.
+
+The OE patch is different to this in that it:
+- reorders the constraints (we keep them in the same order)
+- its definition of attr "type" seem not to correspond to the insns it uses
+ (so here we define them to what seems right)
+- in movdf, it replaces operand 1 "general_operand" with "soft_df_operand" and
+ removes the first two clauses (r<->Q = memory indexed by base register)
