Thanks for working on this.  Unfortunately it seems the

change (commit message didn't make it into this PR because of an extra pr after

/ ) regressed i386/pr45352.c testcase on i?86.

./cc1 -m32 -O3 -march=amdfam10 -fselective-scheduling2 -fsel-sched-pipelining

-funroll-all-loops gcc.target/i386/pr45352.c

ICEs now with:

  Vlad, can you please have a look?  Thanks.

Ok, I started to work on this.

I've tried to fix this similarly to PR48721:

--- sched-deps.c.jj22012-10-17 17:18:21.0 +0200

+++ sched-deps.c2012-11-07 12:15:05.246124552 +0100

@@ -2907,7 +2907,10 @@ sched_analyze_insn (struct deps_desc *de

 {

   rtx next;

   next = next_nonnote_nondebug_insn (insn);

-  if (next  BARRIER_P (next))

+  /* Don't schedule anything after an unconditional return jump.  */

+  if (returnjump_p (insn)  ! condjump_p (insn))

+reg_pending_barrier = TRUE_BARRIER;

+  else if (next  BARRIER_P (next))

 reg_pending_barrier = MOVE_BARRIER;

   else

 {

but that didn't help.  The difference between reload and LRA seems to be just

in that old reload emitted a deleted note after the prefetch for some reason,

and after adding simple_return jump and barrier after it that note was still

following the barrier, while with LRA there is no such deleted note at the end.

Still the scheduler seems to attempt to do DCE of the prefetch (why?  Isn't the

prefetch meaningful on its own?).  Vlad, can you please have a look?  Thanks.
