+       * configure{,.in} (--enable-sim-icache): If argument is define,
+       add -R to flags passed to igen.
+
+       * igen.c (stdlib.h): Include if the system supplies one.
+       (semantics_use_cache_struct): New global for -R flag to say
+       semantics is to use the cache structure directly rather than
+       putting the values into local variables.
+       (first_undef, last_undef): New structures to remember names to
+       #undef if -R.
+       (lf_print_c_extraction): If -R and this is semantics, emit names
+       as #defines pointing to the cache structure, rather than loading
+       the values into local variables.
+       (lf_print_c_semantic_function): If -R, #undef all of the names
+       defined in lf_print_c_extraction.
+       (main): Recognize -R.
+
+       * idecode_fields.h (SPR_*): Redefine spr_* macros as SPR_* to
+       avoid a name confict if -R passed to igen.
+
+       * ppc-instructions (mfspr, mtspr): Rename spr field to SPR.
+       (model_data): Add field to count the various # of CRs that the
+       mtcrf instruction used.
+       (model_mon_info): Return structures counting the # of CRs that the
+       mtcrf instruction used.
+
+       * mon.c (mon_sort_instruction_names): New function to sort
+       instruction names alphabetically.
+       (mon_print_info): Call qsort with mon_sort_instruction_names to
+       sort instruction names.
+       
        * debug.h (ITRACE): Make printf_filtered arguments type correct.
        * idecode_expression.h (CR0_COMPARE): Ditto.
        * psim.c (psim_read_register): Ditto.
