+      as trashed by call insns)
+
+   -- preserve x87 ST stack discipline across function calls.  Sigh.
+
+   -- Check doHelperCall: if a call is conditional, we cannot safely
+      compute any regparm args directly to registers.  Hence, the
+      fast-regparm marshalling should be restricted to unconditional
+      calls only.
