Fri Nov 10 06:39:46 1995 Michael Meissner <meissner@tiktok.cygnus.com>
+ * table.c (table): New field nr_model_fields.
+ (table_open): New parameter nr_model_fields.
+ (table_entry_read): Parse model fields that begin with a '*' after
+ each instruction.
+ * igen.c, dgen.c: Change callers of table_open.
+
+ * igen.c: Add support for dumping model specific information in
+ model.h and model.c.
+ (insn_field_name): Delete unused array.
+ (global variables): Make global variables static, so we can tell
+ when they are no longer used.
+ (cache_semantic_actual): Delete unused variable.
+ (insn_table_load_insns): If the insn is really a machine model,
+ call model_table_insert instead of other processing.
+ (model_table_insert): New function to handle defining the
+ functional units of a particular machine model.
+ (insn_table): Add last_function field so we can add functions at
+ the end.
+ (insn_table_insert_function): Use last_function field when
+ appending new function.
+
+ * ppc-instructions: Add a few model specific information for 603,
+ 603e, and 604 for testing purposes.
+
+ * table.h (table_model_entry): New linked list to hold model
+ specific information, one per line.
+ (table_entry): Add model_first, model_last fields.
+
* configure.in (--enable-sim-inline): If gcc is found and
--enable-sim-inline is not specified, defaine DEFAULT_INLINE to 1,
not 2.
+ (--enable-sim-reserved-bits): New switch to check whether reserved
+ bits are set in the instruction.
+ (--enable-sim-opcode): Make complex the default.
+ (all switches): Add appropriate checks and error messages.
* configure: Regenerate.
+ * Makefile.in (RESERVED_CFLAGS): New variable set by
+ --enable-sim-reserved-bits.
+ (CONFIG_CFLAGS): Include RESERVED_CFLAGS.
+ (BUILT_SRC): igen now generates model.c and model.h.
+ (LIB_OBJ): Include table.o.
+ (tmp-igen): Add -m/-M options to write model.c/model.h.
+ (model.o): New object.
+ (CPU_H): Include model.h.
+
+ * cpu.h: Include model.h.
+
+ * std-config.h (WITH_RESERVED_BITS): Define.
+ (MODEL_INLINE): Ditto.
+
+ * options.c (print_options): Print out WITH_RESERVED_BITS.
+
Thu Nov 9 12:22:15 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* configure.in: If --silent, don't output information messages.
