Created attachment 22539
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22539
gcc46-pr43897.patch

So something like this?  Completely untested, appart from the testcase (with a
cross).

------- Comment #2 from wilson at gcc dot gnu dot org  2010-04-26 21:40 -------
GCC-4.3 is still broken; my testcase just doesn't happen to fail there.  I
suspect this is broken all of the way back to gcc-2.95.  This does point to
where the problem was exposed though.  It is the
-msched-stop-bits-after-every-cycle patch, which emits stop bits when we hit
hardware resource limits.  I get accidentally correct code on mainline if I use
-mno-sched-stop-bits-after-every-cycle.  This patch was added in between
gcc-4.3 and gcc-4.4.
