	instruction is in, and whether it is part of a parallel operation.
	(_state): Add ins_type field.
	({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
	(ins_type_counters): Counters for the various instruction types.
	({left,right}_nops): Counters for the number of nops in each
	container.
	(d10v_debug): New variable to indicate whether debugging is turned
	on.

	* simops.c: (all functions): Change all #ifdef DEBUG code so that
	the input and output values can be traced, along with the
	instruction type.  Make the -t option enable tracing.
	(all functions): Change printf calls to use the printf_filtered
	function in the callback table.

	* interp.c (_leftright): New enumeration to say whether 2 short
	instructions are done left first or right first.
	(do_{long,2_short,parallel}): Indicate in the machine state which
	type of instruction this is.  Count each of the types of
	instructions executed.
	(sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
	flag is set.
	(sim_resume): Pass left/right indication to do_2_short.
	(all functions): Change printf calls to use the printf_filtered
	function in the callback table.
	(sim_trace): Turn on debug flag if DEBUG was defined, and call
	sim_resume.
	(sim_info): Print out statistics on instructions.
	(sim_{trace,create_inferior}): Eliminate extraneous output unless
	debugging.
	(sim_open): If args == -t and DEBUG was defined, set d10v_debug.
	Only initialize the hash table the first time sim_open is called.

	* Makefile.in: Make objects depend on d10v_sim.h.
	({,SIM_}CFLAGS): Include configure dependent switches.  Setting
	CFLAGS does not override host/target defines or SIM_CFLAGS.
	(CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
	(run): By default, the math library is not needed to be linked
	in.
	({BFD,LIBIBERTY}_LIB): Define as variables so they can be
	overridden.
	(VPATH): Don't set to anything but @srcdir@ to work with non-GNU
	makes.
	({run,callback}.o): Provide explicit paths to their appropriate
	source directories.
	(gencode{,.o},d10v-opc.o): Split compilation into creating object
	and linking.  Instead of linking in libopcodes.a, just compile
	d10v-opc.o directly to handle canadian cross.
	(CSEARCH): Add opcodes directory.

	* configure.in (--enable-sim-cflags): New switch to allow user to
	set the defaults.
	(CC_FOR_BUILD): Deal with canadian crosses.
	* configure: Regenerate.

Wed Sep 04 04:45:34 1996  Mark Alexander  <marka@cygnus.com>

	* simops.c: Include correct syscall.h for d10v, not host's.
	Fix #ifdef SYS_stat.

Tue Sep  3 14:00:04 1996  Michael Meissner  <meissner@tiktok.cygnus.com>

	* simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
	Add trap 2 to be printf and trap 3 to be putchar.
