Thiemo Seufer 14fb6c5a50 * cp1.c (value_fpr): Don't inherit existing FPR_STATE for
uninterpreted formats. If fmt is one of the uninterpreted types
	don't update the FPR_STATE. Handle fmt_uninterpreted_32 like
	fmt_word, and fmt_uninterpreted_64 like fmt_long.
	(store_fpr): When writing an invalid odd register, set the
	matching even register to fmt_unknown, not the following register.
	* interp.c (sim_open): If STATE_MEM_SIZE isn't set then set it to
	the the memory window at offset 0 set by --memory-size command
	line option.
	(sim_store_register): Handle storing 4 bytes to an 8 byte floating
	point register.
	(sim_fetch_register): Likewise for reading 4 bytes from an 8 byte
	register.
	(sim_monitor): When returning the memory size to the MIPS
	application, use the value in STATE_MEM_SIZE, not an arbitrary
	hardcoded value.
	(cop_lw): Don' mess around with FPR_STATE, just pass
	fmt_uninterpreted_32 to StoreFPR.
	(cop_sw): Similarly.
	(cop_ld): Pass fmt_uninterpreted_64 not fmt_uninterpreted.
	(cop_sd): Similarly.
	* mips.igen (not_word_value): Single version for mips32, mips64
	and mips16.
