After r147995,
gcc.c-torture/compile/20080903-1.c fails for -O3 -g on SH with
20080903-1.c:12: internal compiler error: in dwarf2out_begin_epilogue, at
dwarf2out.c:2689
In failing case, sched2 moves a frame related insn in prologue
after NOTE_INSN_EPILOGUE_BEG note:
(note 42 6 43 2 NOTE_INSN_EPILOGUE_BEG)
(insn:TI 43 42 35 2 20080903-1.c:12 (set (reg:SI 7 r7)
(const_int 4096 [0x1000])) 175 {movsi_ie} (nil))
(insn/f 35 43 36 2 20080903-1.c:5 (set (reg/f:SI 14 r14)
(reg/f:SI 15 r15)) 175 {movsi_ie} (nil))
I'm testing a patch which emits a blockage insn before insn 35
when dwarf2out_do_frame returns true. We already do so when
exception handling is enabled. It will change the code with
-g. This isn't good in general but wouldn't be a real problem
in the above situation because if such movement of the frame insn
happened, then no one can expect -g works well in the first place.
