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
11 invalidate is issued from problem state.

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

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

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

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

638 * Makefile.in: Uncomment built file dependencies.
640 * configure.in: Rewrite --enable-sim switch handling to use the
641 autoconf builtins so it works correctly if the configure or
642 Makefile.in files are modified and make decides to rebuild
643 Makefile. Also document all of the --enable-sim switches
644 supported. Check whether getrusage and sys/resource.h are
646 * config.in: Regenerate.
647 * configure: Regenerate.

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

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

763 invalid instructions.
765 * configure.in: Add support for more --enable-sim-* switches.
766 Use config.make and config.hdr to write to Makefile and config.h

785 * Makefile.in: Add various Make variables that the various
788 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
789 and optimizing by default.
791 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
793 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
794 make them functions again. Appears 2.6.3 is confused by just a
797 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
799 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
801 * psim.c (psim_create): Not correctly checking that runtime
802 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
803 matched the compiled in ones.
805 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
806 trace_semantics is now different to trace_idecode, the former
809 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
811 * ppc-instructions (mtsrin): Missing instruction
812 * ppc-instructions (mfsrin): Missing instruction
813 * ppc-instructions (eieio): Missing instruction
815 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
817 * build-psim: New shell script - see internals for usage,
818 simplifies the process of building custom simulators.
820 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
822 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
823 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
824 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
825 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
826 the instruction or data critical paths.
828 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
829 not on critical path.
831 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
832 the inclusion of device_tree.c/emul_generic.c.
834 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
836 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

843 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
845 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
846 the processor is started. Fixes problem of registers being
847 undefined when restarting from within gdb.
849 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
850 instruction cache (if present). Fixes problem of cpu caching gdb
851 breakpoint instructions.
853 FIXME: PSIM sometimes aborts calling error(), it should instead
854 call sim_error() say which takes care of housekeeping such as
855 saving the CIA before calling error.
857 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
858 used when restarting a simulation because the latter has the
859 unwanted side effect (well I as a kernel hacker think it is) of
860 performing an isync when the instruction stream doesn't contain
863 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
865 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
866 monitoring module. Counts both instructions issued and
869 * NOTE: mon does not contain to count instruction loads as this
870 information is already available from the mon_issue() hook.
872 * FIXME: mon doesn't have access to register usage information.
873 This is needed if the user wants to monitor things like register
876 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
878 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
879 a common monitor to each of the cpus. Delete
880 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
881 replaced by copied code in mon.[hc].
883 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
885 * sim_calls.c, main.c, psim.c (psim_create): always create
886 `WITH_SMP' cpus. The actual number of CPU's active in a
887 simulation run is taken from the device node: /init/smp (an
888 integer). WITH_SMP changed to 2 (remember to put it back to 0).
890 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
892 * system.c: More system call emulation. If code appears NetBSD
893 specific, make conditional to being compiled on a NetBSD system
896 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
898 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
899 lf.[ch](new), table.[ch](new): Split into two generators - igen
900 that outputs the instruction tables and dgen that outputs the spr
901 tables. Add -f (filter out) flag to igen to filter out certain
902 instructions (ex 64 bit ones) from the created tables. Include
903 $(LIBIBERTY_LIB) in link options in case host lacks some libc
906 * NOTE: igen, since it was originally written for the
907 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
909 * Makefile.in, std-config.h, ppc-cache-rules(new),
910 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
911 cache-rule and opcode-rule tables from macros found std-config.h.
912 Delete corresponding macro's from std-config.h.
914 * FIXME: under this new igen scheme, when playing around with igen
915 options, you'll find that depenencies don't work very well.
917 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
918 an table of all the instructions. Code to output a type
919 enumerating all the instructin names.
921 * igen.c(lf_print_c_semantic): Move call to increment instruction
922 counter so that it occures _after_ the instruction has been fully
923 validated, was double counting illegal/invalid instructions. Add
924 conditional so only compiled in when WITH_PROFILE enabled (enabled
927 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
928 itable.h, count individual instruction types not just total,
929 adjust reporting functions to output this.
931 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
932 Had 32./ instead of 31./
934 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
935 bitrot - updated to use newer CR register operators.
937 * ppc-instructions (64bit Floating Convert from Integer
938 Doubleword): Correct call to Round_Float().
940 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
942 * basics.h: #include "sim_callbacks.h" earlier so that its
943 prototypes are declared in all other header files.
945 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
946 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
949 * FIXME: the bits.h/bits.c macro's should be replaced with
950 (inline) c functions.
952 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
953 Add size of buffer argument to functions writing a string into a
954 buffer. Check for buffer overflow.
956 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
958 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
959 of each device. Make parameter names consistent so macros work.
960 Use macro's in device functions.
962 * device_tree.c, devices.h, devices.c: include path to device in a
963 devices node when creating it.
965 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
967 * core.c: add tracing of core-device, adjust parameter names in
968 core functions to be consistent with those in devices*.
970 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
972 * debug.h, debug.c (trace_option): New function. Parses the trace
973 option, updating the trace array.
975 * debug.h, debug.c (trace_usage): New function. Outputs the list
976 of all possible trace options.
978 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
979 parse trace options specified with the simpler -t flag. Adjust
982 * FIXME: basic parsing of command line options is still duplicated
983 by main.c and sim_calls.c
985 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
987 * Makefile.in (clean): Delete *.i and *.out files.
989 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
990 macros for either assignment or return. Fix SWAP_8 to use a
991 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
992 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
993 that hardwired swapping on/off, let optimizer delete dead code.
995 * main.c (main): Add printf that we caught a signal and print out
998 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1000 * Makefile.in: Remove tabs from otherwise empty line.

1010 instructions here so it works with caching.
1011 (gen_idecode_c): Move from here.
1013 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1015 * gen.c, ppc-instructions, psim.c: Fix code for generating
1016 cracking instruction cache. Delete the code that cached just the
1017 result from doing an instruction lookup - this ran slower than no
1020 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1022 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1024 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1025 TCL when gdb is linked with the simulator.
1026 * debug.c (ppc_trace): Ditto.
1027 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1028 * main.c (main): Ditto.
1030 * cpu.c (cpu_add_commas): Remove extra static.
1032 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1034 * Makefile.in (psim.o): Now that inlines are turned on, make
1035 psim.o depend on all sources.
1037 * cpu.c (cpu_add_commas): New function to format a long with
1039 (cpu_print_info): Use it to print number_of_insns.
1041 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1043 (ENDIAN_N): If both target and host byte orders are known, don't
1044 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1046 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1047 to allow target specific H2T_n/T2H_n macros to be used.
1048 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1049 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1050 of the 3 instruction sequence that runs on 386s.
1052 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1053 specified on the compile line.
1054 (WITH_BSWAP): If not defined, define as 0.
1056 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1057 default inline support. Pass INLINE_CFLAGS when compiling.
1059 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1060 INLINE_DEVICES since GCC doesn't like inline functions that
1061 accept variable arguments.
1062 (stack_ioctl_callback): Make function just static because GCC
1063 doesn't like inline functions that accept variable arguments.
1065 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1067 * inline.c: Correct pathnames of included C files to match current
1070 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1071 non-zero, define STATIC_DEVICES to be static.
1073 * std-config.h (INLINE): If GNU C and optimizing, define this as
1075 (DEFAULT_INLINE): If not defined, define as 0.
1076 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1077 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1078 ({SPREG,IDECODE}_INLINE): Ditto.
1080 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1082 * ppc-instructions: Initial cut of floating point suport added.
1083 Of note include - use of host IEEE floating point instructions,
1084 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1085 currently a pretty sight.
1087 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1088 merge into core.h, core.c, core_n.h. The type memory_map replaced
1089 with core_map. This removes a level of pointer indirection when
1090 translating an address.
1092 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1094 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1099 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1100 most of the other functions in sim_calls.c.
1102 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1103 Add macros to better cover up `generic' code. Makes it possible
1104 to step through the generic code!
1106 * vm.c, vm_n.h, Makefile.in: ditto
1108 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1110 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1111 callback interface so that there is a read/write buffer but no
1112 read/write_word. VEA default memory read/write handler sometimes
1113 couldn't resolve an access and of those some were for a memory
1114 fault and some were because gdb was making a bogus request.
