--- Comment #3 from Kazumoto Kojima <kkojima at gcc dot gnu.org> ---
I've wrongly cut&paste call_value_pcrel.  It's

(define_insn_and_split "call_value_pcrel"
  [(set (match_operand 0 "" "=rf")
        (call (mem:SI (match_operand:SI 1 "symbol_ref_operand" ""))
              (match_operand 2 "" "")))
   (use (reg:SI FPSCR_MODES_REG))
   (use (reg:SI PIC_REG))
   (clobber (reg:SI PR_REG))
   (clobber (match_scratch:SI 3 "=&r"))]
   ...

I think that the last clobber should be

   (clobber (match_scratch:SI 3 "=&r"))]

i.e. the scratch register is early clobbered.  With that change,
it looks the wrong code go away.  I'll come up with the tested
patch for all similar *call_*pcrel insns.
