8 from PPC_FUNCTION_UNIT_xxx enums. Change PPC_UNIT_UNKNOWN ->
9 PPC_UNIT_BAD. Add TRACE(trace_tbd) for all data cache
10 instruction.s. Signal illegal instruciton if data cache block

14 max size for the model specific fields.
15 (model_c_insn): Use max_model_fields_len to size fields.

91 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
93 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
94 inline.. Only problem being that with ppc-opcode-simple this gave
95 it the chance to inline all the idecode functions with potentially
96 disasterous results on a 16mb PC. For moment hobble INLINE.
98 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
101 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
102 Firstly make them errors and secondly remove the options gcc-245
105 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
107 * misc.c (zalloc), cpu.c (cpu_init), devices
108 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
109 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
110 sim_calls.c (zalloc) : replace bzero() with memset().
112 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
113 psim_write_register): replace bcopy() with memcpy().
115 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
117 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
118 force DEFAULT_INLINE to 0 rather then trusting the std
121 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
123 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
124 generation of switch entries in tables - treat the same as
125 cracking/semantic functions.
127 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
128 of a boolean switch statement (field zero or non-zero).
130 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
131 switch/table generation ability of igen.
133 * igen.c (idecode_switch_leaf): Fix code output when a switch
134 statement needs to look up a table.
136 * igen.c (idecode_declare_if_switch): New function called from
137 gen_idecode_c - need to declare any idecode switch functions
138 before they are used in idecode tables.
140 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
141 idecode_crack_insn): Add is_inline_function argument to code
142 printing cracker functions which indicates if STATIC_IDECODE or
143 STATIC_INLINE_IDECODE should be used for definition. For
144 idecode_crack_insn (which implies not duplicating/expanding) don't
145 declare function as inline - we assume that the only time this is
146 code is generated is when things are being tested. For
147 idecode_crack_leaf, make static (instead of INLINE) if the
148 instructions parent is a table as function will always be called
151 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
152 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
153 called directly, all others are called via a table.
155 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
156 semantics_h_insn, semantics_h_function,
157 lf_print_c_semantic_function, semantics_c_function): Add
158 is_inline_function argument to lf_print_semantic_function_header
159 to indicate if an inline or static function declaration/definition
160 should be output. Depending on situtation call accordingly:
161 functions (not instruction semantic routines) are always inline;
162 Semantic routines are made inline when there is no icache (cache
163 will contain the function address) and are duplicating (see above)
164 and the parent of the instruction is a switch statement.
166 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
167 and moved to insn_table_find_opcode_field.
169 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
171 * igen.c (model_c_insn): Suggestion - document the name of the
172 instruction on each line of the instruction model table.
174 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
176 * emul_netbsd.c (do_ioctl): Cleanup compilation.
178 * sim_callbacks.h (__attribute__): Only define if not defined (was
179 already defined on NetBSD host).

184 macro, indicates if the PowerPC's horrible XOR endian mode should
185 be suported. Add to configure and make.
187 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
188 (vm_instruction_map_read): If XOR endian, xor the address
189 with a value from an xor table (indexed by size of access).
191 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
192 set up xor table to xor if there is a conflict between the
193 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
194 check of suported change of endian mode from cpu.c to vm.c.
196 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
197 Hopefully added correct hack to handle XOR endian mode.
199 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
200 little endian mode, the model accepts miss aligned transfers.
202 FIXME: Need to create an `init' device that, during
203 initializatioin for XOR mode, it mushes (XOR address) all the dma
204 data before passing it on to the core for storage. Just like the
207 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
209 * devices.c (halt_io_write_buffer_callback): Use value written to
210 halt device to determine exit status. Thus allowing
211 success/failure of OEA tests.
213 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
215 * ppc-instructions (icbi): If icache present flush it.

227 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
229 * filter_filename.c, Makefile.in: Change so that only dependant on
230 a very limited nr of files. Stops an unnecessary dependency.
232 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
234 * core.c (core_map_find_mapping): Use cpu_halt rather than error
235 to abort an access to an undefined address.

294 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
295 instead of INLINE_SEMANTICS so that the compiler won't keep all of
296 the semantic functions as inline RTL, given that the address of
297 the function is taken which forces outline calls anyway.

630 TIMEBASE_CFLAGS which weren't included.
632 Thu Nov 2 08:54:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
634 * Makefile.in: Uncomment built file dependencies.
636 * configure.in: Rewrite --enable-sim switch handling to use the
637 autoconf builtins so it works correctly if the configure or
638 Makefile.in files are modified and make decides to rebuild
639 Makefile. Also document all of the --enable-sim switches
640 supported. Check whether getrusage and sys/resource.h are
642 * config.in: Regenerate.
643 * configure: Regenerate.
644 * Makefile.in: Add support for all of the variables set with
645 --enable-sim switches.

652 the generated config.h.
654 * device_tree.c: Ditto.
657 * emul_netbsd.c: Ditto.
662 * registers.c: Ditto.
667 * main.c (main): Call psim_print_info with verbose == 2.
669 * mon.c (mon_print_info): Align the cpu number and number of
670 instructions fields. Do not print an instruction category if the
671 CPU did not execute any of those instructions. Print out number
672 of reads and writes. If getrusage is supported, print out number
673 of simulated instructins per second.
675 * configure.in: Add support for --enable-sim-opcode=stupid.
676 * configure: Regenerate.
678 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
680 * std-config (INLINE_DEVICE_TREE): Don't inline either of
681 device_tree.c or devices.c. There is no significant gain.
683 * configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and
686 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
688 * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
689 functions to convert between target and igen internal bit numbers.
690 Make IO go through these functions. Add -b (bit size) and -h (high
691 bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
692 15 for a 16 bit instruction format with the msb given a number 15.
694 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
696 * dgen.c (main): Was outputting optarg even when it was NULL.
698 Tue Oct 31 23:48:33 1995 Andrew Cagney <cagney@highland.com.au>
700 * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h,

716 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
718 * ppc-opcode-stupid: Third example of use of opcode table - this
719 one expands all mtspr/mfspr and branch instructions. Appears to
720 give about a 10% gain in performance if everything enabled. Also
721 takes about 150mb of swap to build.
723 Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
725 * emul_netbsd.c (do_exit): Print arguments and close parenthesis

759 invalid instructions.
761 * configure.in: Add support for more --enable-sim-* switches.
762 Use config.make and config.hdr to write to Makefile and config.h
763 respectively. Don't rewrite Makefile, just append to it.
764 * configure: Regenerate.
765 * config.{make,hdr}: New shell scripts.
767 * Makefile.in: Remove all variables set by configure.in.
768 (psim.o): Depend on $(BUILT_SRC) also.

778 and --enable-sim-endian switch to control various Makefile
780 * configure: Regenerate from configure.in.
781 * Makefile.in: Add various Make variables that the various
784 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
785 and optimizing by default.
787 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
789 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
790 make them functions again. Appears 2.6.3 is confused by just a
793 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
795 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
797 * psim.c (psim_create): Not correctly checking that runtime
798 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
799 matched the compiled in ones.
801 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
802 trace_semantics is now different to trace_idecode, the former
805 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
807 * ppc-instructions (mtsrin): Missing instruction
808 * ppc-instructions (mfsrin): Missing instruction
809 * ppc-instructions (eieio): Missing instruction
811 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
813 * build-psim: New shell script - see internals for usage,
814 simplifies the process of building custom simulators.
816 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
818 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
819 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
820 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
821 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
822 the instruction or data critical paths.
824 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
825 not on critical path.
827 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
828 the inclusion of device_tree.c/emul_generic.c.
830 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
832 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
833 system.[hc]. Start of suport for multiple emulations and
834 emulation state (os_emul object).
836 * emul_generic.[hc]: Start of code to implement proper system call
839 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
841 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
842 the processor is started. Fixes problem of registers being
843 undefined when restarting from within gdb.
845 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
846 instruction cache (if present). Fixes problem of cpu caching gdb
847 breakpoint instructions.
849 FIXME: PSIM sometimes aborts calling error(), it should instead
850 call sim_error() say which takes care of housekeeping such as
851 saving the CIA before calling error.
853 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
854 used when restarting a simulation because the latter has the
855 unwanted side effect (well I as a kernel hacker think it is) of
856 performing an isync when the instruction stream doesn't contain
859 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
861 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
862 monitoring module. Counts both instructions issued and
865 * NOTE: mon does not contain to count instruction loads as this
866 information is already available from the mon_issue() hook.
868 * FIXME: mon doesn't have access to register usage information.
869 This is needed if the user wants to monitor things like register
872 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
874 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
875 a common monitor to each of the cpus. Delete
876 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
877 replaced by copied code in mon.[hc].
879 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
881 * sim_calls.c, main.c, psim.c (psim_create): always create
882 `WITH_SMP' cpus. The actual number of CPU's active in a
883 simulation run is taken from the device node: /init/smp (an
884 integer). WITH_SMP changed to 2 (remember to put it back to 0).
886 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
888 * system.c: More system call emulation. If code appears NetBSD
889 specific, make conditional to being compiled on a NetBSD system
892 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
894 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
895 lf.[ch](new), table.[ch](new): Split into two generators - igen
896 that outputs the instruction tables and dgen that outputs the spr
897 tables. Add -f (filter out) flag to igen to filter out certain
898 instructions (ex 64 bit ones) from the created tables. Include
899 $(LIBIBERTY_LIB) in link options in case host lacks some libc
902 * NOTE: igen, since it was originally written for the
903 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
905 * Makefile.in, std-config.h, ppc-cache-rules(new),
906 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
907 cache-rule and opcode-rule tables from macros found std-config.h.
908 Delete corresponding macro's from std-config.h.
910 * FIXME: under this new igen scheme, when playing around with igen
911 options, you'll find that depenencies don't work very well.
913 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
914 an table of all the instructions. Code to output a type
915 enumerating all the instructin names.
917 * igen.c(lf_print_c_semantic): Move call to increment instruction
918 counter so that it occures _after_ the instruction has been fully
919 validated, was double counting illegal/invalid instructions. Add
920 conditional so only compiled in when WITH_PROFILE enabled (enabled
923 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
924 itable.h, count individual instruction types not just total,
925 adjust reporting functions to output this.
927 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
928 Had 32./ instead of 31./
930 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
931 bitrot - updated to use newer CR register operators.
933 * ppc-instructions (64bit Floating Convert from Integer
934 Doubleword): Correct call to Round_Float().
936 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
938 * basics.h: #include "sim_callbacks.h" earlier so that its
939 prototypes are declared in all other header files.
941 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
942 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
945 * FIXME: the bits.h/bits.c macro's should be replaced with
946 (inline) c functions.
948 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
949 Add size of buffer argument to functions writing a string into a
950 buffer. Check for buffer overflow.
952 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
954 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
955 of each device. Make parameter names consistent so macros work.
956 Use macro's in device functions.
958 * device_tree.c, devices.h, devices.c: include path to device in a
959 devices node when creating it.
961 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
963 * core.c: add tracing of core-device, adjust parameter names in
964 core functions to be consistent with those in devices*.
966 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
968 * debug.h, debug.c (trace_option): New function. Parses the trace
969 option, updating the trace array.
971 * debug.h, debug.c (trace_usage): New function. Outputs the list
972 of all possible trace options.
974 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
975 parse trace options specified with the simpler -t flag. Adjust
978 * FIXME: basic parsing of command line options is still duplicated
979 by main.c and sim_calls.c
981 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
983 * Makefile.in (clean): Delete *.i and *.out files.
985 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
986 macros for either assignment or return. Fix SWAP_8 to use a
987 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
988 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
989 that hardwired swapping on/off, let optimizer delete dead code.
991 * main.c (main): Add printf that we caught a signal and print out
994 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
996 * Makefile.in: Remove tabs from otherwise empty line.
997 Confuses many non-GNU versions of "make".

1005 * gen.c (lf_print_c_semantic_function): Move counting # of
1006 instructions here so it works with caching.
1007 (gen_idecode_c): Move from here.
1009 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1011 * gen.c, ppc-instructions, psim.c: Fix code for generating
1012 cracking instruction cache. Delete the code that cached just the
1013 result from doing an instruction lookup - this ran slower than no
1016 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1018 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1020 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1021 TCL when gdb is linked with the simulator.
1022 * debug.c (ppc_trace): Ditto.
1023 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1024 * main.c (main): Ditto.
1026 * cpu.c (cpu_add_commas): Remove extra static.
1028 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1030 * Makefile.in (psim.o): Now that inlines are turned on, make
1031 psim.o depend on all sources.
1033 * cpu.c (cpu_add_commas): New function to format a long with
1035 (cpu_print_info): Use it to print number_of_insns.
1037 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1039 (ENDIAN_N): If both target and host byte orders are known, don't
1040 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1042 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1043 to allow target specific H2T_n/T2H_n macros to be used.
1044 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1045 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1046 of the 3 instruction sequence that runs on 386s.
1048 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1049 specified on the compile line.
1050 (WITH_BSWAP): If not defined, define as 0.
1052 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1053 default inline support. Pass INLINE_CFLAGS when compiling.
1055 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1056 INLINE_DEVICES since GCC doesn't like inline functions that
1057 accept variable arguments.
1058 (stack_ioctl_callback): Make function just static because GCC
1059 doesn't like inline functions that accept variable arguments.
1061 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1063 * inline.c: Correct pathnames of included C files to match current
1066 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1067 non-zero, define STATIC_DEVICES to be static.
1069 * std-config.h (INLINE): If GNU C and optimizing, define this as
1071 (DEFAULT_INLINE): If not defined, define as 0.
1072 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1073 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1074 ({SPREG,IDECODE}_INLINE): Ditto.
1076 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1078 * ppc-instructions: Initial cut of floating point suport added.
1079 Of note include - use of host IEEE floating point instructions,
1080 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1081 currently a pretty sight.
1083 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1084 merge into core.h, core.c, core_n.h. The type memory_map replaced
1085 with core_map. This removes a level of pointer indirection when
1086 translating an address.
1088 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1090 * Makefile.in et.al (sorry): tweek to use new core, core_map and
1093 Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@highland.com.au>
1095 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1096 most of the other functions in sim_calls.c.
1098 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1099 Add macros to better cover up `generic' code. Makes it possible
1100 to step through the generic code!
1102 * vm.c, vm_n.h, Makefile.in: ditto
1104 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1106 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1107 callback interface so that there is a read/write buffer but no
1108 read/write_word. VEA default memory read/write handler sometimes
1109 couldn't resolve an access and of those some were for a memory
