Sorry, I've closed this bug hastily though the bug is not fixed 4.3 branch; the
patch I was reffering to was only committed to trunk.

This was fixed on trunk, presumably by IRA. I've also checked a clean up patch
that fixed this failure on 4.3. See
http://gcc.gnu.org/ml/gcc-patches/2008-11/msg01031.html.

This is fixed only on trunk; 4.3 still has the bug. Do you think it's
appropriate to close it anyway?

There are several (4, I think) patches posted in gcc-patches@ for this bug. A
reload/recog maintainer is needed to choose the most appropriate one.

Maxim, have you had time to look at this bug? Given that it is generating bad
code and is in 4.3.0 and 4.3.1 I was wondering if it will be fixed for 4.3.2.
Sorry for the delay. I

There are two problems here:
1. The immediate problem is that movsi_m68k doesn't allow (const) to be moved
to data register (see last alternative if movsi_m68k).
2. For reason, which I have not yet investigated
