+To add a new target:
+
+ devo/sim/common/gennltvals.sh
+
+ Add your new processor target (you'll need to grub
+ around to find where your syscall.h lives).
+
+ devo/sim/<processor>/Makefile.in
+
+ Add the definition:
+
+ ``NL_TARGET = -DNL_TARGET_d10v''
+
+ just before the line COMMON_POST_CONFIG_FRAG.
+
+ devo/sim/<processor>/*.[ch]
+
+ Include targ-vals.h instead of syscall.h.
