+ * configure.in: Rewrite --enable-sim switch handling to use the
+ autoconf builtins so it works correctly if the configure or
+ Makefile.in files are modified and make decides to rebuild
+ Makefile. Also document all of the --enable-sim switches
+ supported. Check whether getrusage and sys/resource.h are
+ supported.
+ * config.in: Regenerate.
+ * configure: Regenerate.
+ * Makefile.in: Add support for all of the variables set with
+ --enable-sim switches.
+
+ * Makefile.in (clean): make clean now removes all built sources as
+ well.
+
+ * cpu.c: Use HAVE_STRING_H, HAVE_STRINGS_H, HAVE_UNISTD_H,
+ HAVE_TIME_H, HAVE_SYS_TIMES_H, HAVE_SYS_RESOURCE_H defined in
+ the generated config.h.
+ * debug.c: Ditto.
+ * device_tree.c: Ditto.
+ * devices.c: Ditto.
+ * dgen.c: Ditto.
+ * emul_netbsd.c: Ditto.
+ * igen.c: Ditto.
+ * lf.c: Ditto.
+ * misc.c: Ditto.
+ * psim.c: Ditto.
+ * registers.c: Ditto.
+ * sim_calls.c: Ditt.
+ * table.c: Ditto.
+
+
* main.c (main): Call psim_print_info with verbose == 2.
* mon.c (mon_print_info): Align the cpu number and number of
instructions fields. Do not print an instruction category if the
- CPU did not execute any of those instructions.
+ CPU did not execute any of those instructions. Print out number
+ of reads and writes. If getrusage is supported, print out number
+ of simulated instructins per second.
* configure.in: Add support for --enable-sim-opcode=stupid.
* configure: Regenerate.
