x86 bootstrap failure

[David Edelsohn]

	I do not believe your patch caused the failure.  AIX compiler
builds but fails later.  I tried rebuilding without your patch, but it
still failed. 

	The only three patches since my previous successful bootstrap are:

Kenner

2001-12-29  Jakub Jelinek  <jakub@redhat.com>

        * cfglayout.c (insert_intra_before_1): New.
        (insert_inter_bb_scope_notes): Emit sibling block notes which don't
        span multiple basic blocks.

2001-12-29  Richard Henderson  <rth@redhat.com>

        * loop.c (prescan_loop): Set has_multiple_exit_targets for exception
        edges.  Rearrange jump interpretation code to use pc_set.
        (check_dbra_loop): Examine has_multiple_exit_targets not exit_count.

        * sched-deps.c (sched_analyze_insn): Set scheduling barrier for
        all insns that can throw, not just if flag_non_call_exceptions.

I will try workout Jakub's patch now.
