Browse Source 
* config/rx/predicates.md (rx_zs_comparison_operator): Remove
	lt and ge.
	* config/rx/rx.md (abssi2_flags): Use CC_ZSmode rather than
	CC_ZSOmode.
	* config/rx/rx.c (rx_print_operand): Use "lt" and "ge" suffixes
	instead of "n" and "pz".
	(flags_from_code): LT and GE tests need CC_FLAG_O as well as
	CC_FLAG_S.
