--- Comment #9 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-11-30 12:17:31 UTC ---
Confirmed.

Also doesn't work with -flto-partition=none:

> ./xgcc -B. -o t t.c -flto -m32 -march=i386 -flto-partition=none
In file included from t.c:16:0,
                 from :0:
t.c: In function 'foo':
t.c:16:15: internal compiler error: in convert_move, at expr.c:326
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
lto-wrapper: ./xgcc returned 1 exit status
collect2: lto-wrapper returned 1 exit status

but we agreed that a target option that changes the mode of types isn't
valid and should be rejected by the target.  See PR45325 (of which this
is IMHO a duplicate).
