Re: CVS i386-linux native build failure

[Toshiyasu Morita <tm at netcom dot com>]

Looks like the abort is happening in this code:

if (optimize && INSN_DELETED_P (after))
  abort();

because:

(xxgdb) call debug_rtx(after)

(note/v 51 2 4 [bb 0] NOTE_INSN_BASIC_BLOCK)

Is this note a deleted insn?
