+	* configure.in: Define target_cpu_default for v850 targets.
+	* configure: Regenerate
+
+	* config/v850/v850.h (TARGET_CPU_generic): Define.
+	(GO_IF_LEGITIMATE_ADDRESS): Insist that SImode and larger constant
+	addresses are 4 byte aligned.
+
+	* config/v850/v850.c (print_operand): Cope with 'R' format DFmode
+	addresses.
