+ * simops.c (trace_input): Use find_nearest_line to print line
+ number, function name or file name of PC.
+
+Wed Sep 11 16:44:37 1996 Michael Meissner <meissner@tiktok.cygnus.com>
+
+ * simops.c: Add tracing support. Use SEXTxx macros instead of
+ doing hardwired shifts.
+
+ * configure.in (--enable-sim-cflags): Add switch to add additional
+ flags to simulator buld. If --enable-sim-cflags=trace, turn on
+ tracing.
+ * configure: Regenerate.
+
+ * Makefile.in: Don't require a VPATH capable make if configuring
+ in the same directory. Don't use CFLAGS for configuration flags.
+ Add flags from --enable-sim-cflags. Support canadian cross
+ builds. Rebuild whole simulator if include files change.
+
+ * interp.c (v850_debug): New global for debugging.
+ (lookup_hash,sim_size,sim_set_profile): Use
+ printf_filtered callback, instead of calling printf directly.
+ (sim_{open,trace}): Enable tracing if -t and compiled for tracing.
+
+ * v850_sim.h: Use limits.h to set the various sized types.
+ (SEXT{5,7,16,22}): New macros.

+
+ * interp.c (hash): Make this an inline function
+ when compiling with GCC. Simplify.
+ * simpos.c: Explicitly include "sys/syscall.h". Remove
+ some #if 0'd code. Enable more emulated syscalls.

+ instructions. Make the simulator stop when a halt
+ instruction is encountered. Very crude support for
+ emulated syscalls (trap 0).
+ * v850_sim.h: Include "callback.h" and declare
+ v850_callback. Items in the operand array are 32bits.
