+	* interp.c (sim_open): Accept bfd_mach_v850e1.
+	* v850-dc: Add entry for v850e1.
+	* v850.igen: Add support for v850e1.
+	Add code for DBTRAP and DBRET instructions.
+	(dbtrap): Create a separate v850e1 specific instruction.
+	Only generate a trap if the target is not the v850e1.
+	Otherwise treat it as a special kind of branch.
+	(break): Mark as v850/v850e specific.
+	
 2003-05-16  Ian Lance Taylor  <ian@airs.com>
 
 	* Makefile.in (SHELL): Make sure this is defined.
