+ * 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.
