+ * endian.c: New file. Move endian functions here from interp.c.
+ Optimize code, and make it work as either inline functions or as a
+ separate file.
+
+ * interp.c: Move endian functions from here to endian.c.
+
+ * Makefile.in (INCLUDE): Add endian.c.
+ (run,libsim.a): Add dependency on endian.o.
+ (endian.o): Add dependency.
+
+ * d10v_sim.h (read/write support): Always go through the machine
+ independent endian functions. If compiling with GCC and
+ optimizing, include endian.c so the endian functions are inlined.
+
* simops.c (OP_5F00): Correct tracing of accumulators.
