* combine.c (make_extraction): If no mode is specified for an operand of insv, extv, or extzv, default it to word_mode. (simplify_comparison): Similarly. * expmed.c (store_bit_field): Similarly. (extract_bit_field): Similarly. * function.c (fixup_var_regs_1): Similarly. * recog.c (validate_replace_rtx_1): Similarly. * mips.md (extv, extzv, insv expanders): Default modes for most operands. Handle TARGET_64BIT. (movdi_uld, movdi_usd): New patterns. From-SVN: r22439
