--- 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.
