Wed Oct 16 13:50:06 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* 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.
