[Bug target/28490] New: [4.2 regression] ICE in ia64_expand_move, at config/ia64/ia64.c:1088

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I get the following ICE with gcc 4.2 on ia64 at -O1.  It doesn't happen with
4.0 or 4.1.

tbm@coconut0:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O1 mini.c
mini.c: In function 'readtoken1':
mini.c:60: internal compiler error: in ia64_expand_move, at
