--- Comment #8 from ktkachov at gcc dot gnu.org ---
The ICE is in the wide-int bit_and code when trying to process the rtx:
(and:SI
(const_int 4294963215 [0xfffff00f])
(const_int 4111 [0x100f])
)
In particular it seems to have problems constructing a wide-int for
(const_int 4294963215 [0xfffff00f])
Richard, does the trace give you any ideas on this?
