As mentioned here:
http://gcc.gnu.org/ml/gcc-patches/2010-02/msg00780.html
Just building a simple: int main(void) { return 0; }
ICEs at -O1 or -O2. This ICEs as we call add_reg_note with an insn note:
(note 21 12 22 2 NOTE_INSN_DELETED)
And REG_NOTES causes the next insn rtx gets modified for some reason.

spu-elf is neither a primary nor a secondary platform. But, confirmed, as
I originally reported this.

My anaylis of this bug is that this bug is very generic and could
cause issues on any target.

------- Comment #3 from pinskia at gcc dot gnu dot org 2010-03-13 23:42 -------
With RTL checking turned on, we get
t.c:4:1: internal compiler error: RTL check: access of elt 7 of 'note' with
last elt 6 in add_reg_note, at rtlanal.c:1902
Which is what I expected to get. I forgot that rtl checking is disabled by
default.

------- Comment #4 from pinskia at gcc dot gnu dot org 2010-03-13 23:59 -------
So right after the NOTE_INSN_EPILOGUE_BEG, we have a NOTE_INSN_DELETED. The
spu back-end emits it with a comment of:
/* A NOTE_INSN_DELETED is supposed to be at the start and end of
the "toplevel" insn chain. */
emit_note (NOTE_INSN_DELETED);
Ok, this is a target issue, no other target emits the note at the beginging of
the epilogue at all. The comment about toplevel insn chain is not true here as
we are always inside a function here. The comment was copied from rs6000 where
it was emitting the "text" based epilogue (or rather the non scheduled version)
which is not considered inside a function at that point.

Patch that needs testing
I don't have a machine setup up to test this patch on but it works for the
simple testcase in the bug report.

It looks obvious to me.
