ktkachov at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rsandifo at gcc dot gnu.org --- 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?
