68 code successful/unsuccessful branch predictions, and the number of
69 conditional branches that fell through.
71 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>

143 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
144 inline.. Only problem being that with ppc-opcode-simple this gave
145 it the chance to inline all the idecode functions with potentially
146 disasterous results on a 16mb PC. For moment hobble INLINE.
148 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
151 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
152 Firstly make them errors and secondly remove the options gcc-245
155 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
157 * misc.c (zalloc), cpu.c (cpu_init), devices
158 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
159 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
160 sim_calls.c (zalloc) : replace bzero() with memset().

165 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
167 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
168 force DEFAULT_INLINE to 0 rather then trusting the std

173 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
174 generation of switch entries in tables - treat the same as
175 cracking/semantic functions.
177 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
178 of a boolean switch statement (field zero or non-zero).
180 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
181 switch/table generation ability of igen.
183 * igen.c (idecode_switch_leaf): Fix code output when a switch
184 statement needs to look up a table.
186 * igen.c (idecode_declare_if_switch): New function called from
187 gen_idecode_c - need to declare any idecode switch functions
188 before they are used in idecode tables.
190 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
191 idecode_crack_insn): Add is_inline_function argument to code
192 printing cracker functions which indicates if STATIC_IDECODE or
193 STATIC_INLINE_IDECODE should be used for definition. For
194 idecode_crack_insn (which implies not duplicating/expanding) don't
195 declare function as inline - we assume that the only time this is
196 code is generated is when things are being tested. For
197 idecode_crack_leaf, make static (instead of INLINE) if the
198 instructions parent is a table as function will always be called
201 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
202 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
203 called directly, all others are called via a table.
205 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
206 semantics_h_insn, semantics_h_function,
207 lf_print_c_semantic_function, semantics_c_function): Add
208 is_inline_function argument to lf_print_semantic_function_header
209 to indicate if an inline or static function declaration/definition
210 should be output. Depending on situtation call accordingly:
211 functions (not instruction semantic routines) are always inline;
212 Semantic routines are made inline when there is no icache (cache
213 will contain the function address) and are duplicating (see above)
214 and the parent of the instruction is a switch statement.
216 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
217 and moved to insn_table_find_opcode_field.
219 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
221 * igen.c (model_c_insn): Suggestion - document the name of the
222 instruction on each line of the instruction model table.
224 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
226 * emul_netbsd.c (do_ioctl): Cleanup compilation.
228 * sim_callbacks.h (__attribute__): Only define if not defined (was
229 already defined on NetBSD host).

234 macro, indicates if the PowerPC's horrible XOR endian mode should
235 be suported. Add to configure and make.
237 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
238 (vm_instruction_map_read): If XOR endian, xor the address
239 with a value from an xor table (indexed by size of access).
241 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
242 set up xor table to xor if there is a conflict between the
243 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
244 check of suported change of endian mode from cpu.c to vm.c.
246 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
247 Hopefully added correct hack to handle XOR endian mode.
249 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
250 little endian mode, the model accepts miss aligned transfers.
252 FIXME: Need to create an `init' device that, during
253 initializatioin for XOR mode, it mushes (XOR address) all the dma
254 data before passing it on to the core for storage. Just like the
257 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
259 * devices.c (halt_io_write_buffer_callback): Use value written to
260 halt device to determine exit status. Thus allowing
261 success/failure of OEA tests.
263 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
265 * ppc-instructions (icbi): If icache present flush it.

269 * devices.c (htab_init_callback): Add code to create htab/pte.
271 * devices.c (dma_file, file_init_callback, htab_init_callback):
272 New function - Dma the named file into memory at the specified

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

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

684 * Makefile.in: Uncomment built file dependencies.
686 * configure.in: Rewrite --enable-sim switch handling to use the
687 autoconf builtins so it works correctly if the configure or

690 supported. Check whether getrusage and sys/resource.h are
692 * config.in: Regenerate.

738 * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
739 functions to convert between target and igen internal bit numbers.
740 Make IO go through these functions. Add -b (bit size) and -h (high
741 bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
742 15 for a 16 bit instruction format with the msb given a number 15.
744 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
746 * dgen.c (main): Was outputting optarg even when it was NULL.

766 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
768 * ppc-opcode-stupid: Third example of use of opcode table - this
769 one expands all mtspr/mfspr and branch instructions. Appears to
770 give about a 10% gain in performance if everything enabled. Also
771 takes about 150mb of swap to build.

839 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
840 make them functions again. Appears 2.6.3 is confused by just a
843 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
845 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
847 * psim.c (psim_create): Not correctly checking that runtime
848 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
849 matched the compiled in ones.
851 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
852 trace_semantics is now different to trace_idecode, the former

857 * ppc-instructions (mtsrin): Missing instruction
858 * ppc-instructions (mfsrin): Missing instruction

861 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
863 * build-psim: New shell script - see internals for usage,
864 simplifies the process of building custom simulators.
866 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
868 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
869 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
870 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
871 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
872 the instruction or data critical paths.
874 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
875 not on critical path.
877 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
878 the inclusion of device_tree.c/emul_generic.c.
880 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
882 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

892 the processor is started. Fixes problem of registers being
893 undefined when restarting from within gdb.
895 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
896 instruction cache (if present). Fixes problem of cpu caching gdb
897 breakpoint instructions.
899 FIXME: PSIM sometimes aborts calling error(), it should instead
900 call sim_error() say which takes care of housekeeping such as
901 saving the CIA before calling error.
903 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
904 used when restarting a simulation because the latter has the
905 unwanted side effect (well I as a kernel hacker think it is) of
906 performing an isync when the instruction stream doesn't contain
909 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
911 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
912 monitoring module. Counts both instructions issued and
915 * NOTE: mon does not contain to count instruction loads as this
916 information is already available from the mon_issue() hook.
918 * FIXME: mon doesn't have access to register usage information.
919 This is needed if the user wants to monitor things like register
922 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
924 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach

931 * sim_calls.c, main.c, psim.c (psim_create): always create
932 `WITH_SMP' cpus. The actual number of CPU's active in a
933 simulation run is taken from the device node: /init/smp (an
934 integer). WITH_SMP changed to 2 (remember to put it back to 0).
936 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
938 * system.c: More system call emulation. If code appears NetBSD
939 specific, make conditional to being compiled on a NetBSD system

944 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
945 lf.[ch](new), table.[ch](new): Split into two generators - igen
946 that outputs the instruction tables and dgen that outputs the spr
947 tables. Add -f (filter out) flag to igen to filter out certain
948 instructions (ex 64 bit ones) from the created tables. Include
949 $(LIBIBERTY_LIB) in link options in case host lacks some libc
952 * NOTE: igen, since it was originally written for the
953 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
955 * Makefile.in, std-config.h, ppc-cache-rules(new),
956 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
957 cache-rule and opcode-rule tables from macros found std-config.h.
958 Delete corresponding macro's from std-config.h.
960 * FIXME: under this new igen scheme, when playing around with igen
961 options, you'll find that depenencies don't work very well.
963 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
964 an table of all the instructions. Code to output a type
965 enumerating all the instructin names.
967 * igen.c(lf_print_c_semantic): Move call to increment instruction
968 counter so that it occures _after_ the instruction has been fully
969 validated, was double counting illegal/invalid instructions. Add
970 conditional so only compiled in when WITH_PROFILE enabled (enabled
973 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
974 itable.h, count individual instruction types not just total,
975 adjust reporting functions to output this.

983 * ppc-instructions (64bit Floating Convert from Integer
984 Doubleword): Correct call to Round_Float().
986 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
988 * basics.h: #include "sim_callbacks.h" earlier so that its
989 prototypes are declared in all other header files.
991 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
992 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into

996 (inline) c functions.
998 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
999 Add size of buffer argument to functions writing a string into a
1000 buffer. Check for buffer overflow.

1024 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1025 parse trace options specified with the simpler -t flag. Adjust
1028 * FIXME: basic parsing of command line options is still duplicated
1029 by main.c and sim_calls.c
1031 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1033 * Makefile.in (clean): Delete *.i and *.out files.
1035 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1036 macros for either assignment or return. Fix SWAP_8 to use a
1037 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1038 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1039 that hardwired swapping on/off, let optimizer delete dead code.
1041 * main.c (main): Add printf that we caught a signal and print out

1056 instructions here so it works with caching.
1057 (gen_idecode_c): Move from here.
1059 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1061 * gen.c, ppc-instructions, psim.c: Fix code for generating
1062 cracking instruction cache. Delete the code that cached just the
1063 result from doing an instruction lookup - this ran slower than no
1066 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1068 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).

1085 (cpu_print_info): Use it to print number_of_insns.
1087 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1089 (ENDIAN_N): If both target and host byte orders are known, don't
1090 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1092 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1093 to allow target specific H2T_n/T2H_n macros to be used.
1094 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1095 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1096 of the 3 instruction sequence that runs on 386s.
1098 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1099 specified on the compile line.
1100 (WITH_BSWAP): If not defined, define as 0.

1122 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1123 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1124 ({SPREG,IDECODE}_INLINE): Ditto.
1126 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1128 * ppc-instructions: Initial cut of floating point suport added.
1129 Of note include - use of host IEEE floating point instructions,
1130 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1131 currently a pretty sight.
1133 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1134 merge into core.h, core.c, core_n.h. The type memory_map replaced
1135 with core_map. This removes a level of pointer indirection when
1136 translating an address.
1138 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1140 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1145 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1146 most of the other functions in sim_calls.c.
1148 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1149 Add macros to better cover up `generic' code. Makes it possible
1150 to step through the generic code!
1152 * vm.c, vm_n.h, Makefile.in: ditto
1154 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1156 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1157 callback interface so that there is a read/write buffer but no
1158 read/write_word. VEA default memory read/write handler sometimes
1159 couldn't resolve an access and of those some were for a memory
1160 fault and some were because gdb was making a bogus request.
1162 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1163 eliminate transfer_mode (raw or cooked) parameter from read/write

1174 scand_*): new functions to parse/print fields in device names
1175 while hiding any machine dependency.
1177 * devices.c, psim.c: Change the stack init code so that it is
1178 handled by a device. Arguments passed across using a device ioctl
1181 * devices.h, devices.c: device ioctl callback changed to allow a
1182 variable number of arguments. This gives greater flexability and
1183 greater chance of bugs.
1185 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1187 * main.c (printf_filtered, error): Missing va_end() to close off
1188 variable argument use.

1191 versions of make not handling files being created as side-effects.
1193 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1194 alternative file name to use in output files for things like #line
1197 Makefile.in (tmp-gencode): Use gen -n so that debug info is

1220 At present, print the number of instructions executed.
1222 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1225 * psim.c (psim_print_info): New function to iterate over each of
1226 the CPU's calling cpu_print_info.
1228 * psim.h,cpu.h: Add new declarations.
1230 * sim_calls.c (sim_open): Add argument processing to add the same
1231 switches main.c accepts for the standalone processor.
1232 (sim_close): Call psim_print_info if -I.
1234 * main.c (main): Add comment saying to update sim_calls.c when
1235 adding switches. Add -I to call psim_print_info when done.

1261 * device_tree.c (create_option_device_node): Assume a program is
1262 OEA if the start address is < 4096, not just == 0.

1308 Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney@highland.com.au>
1310 * core.c (core_add_data): First growth of bss was being put at
1311 wrong address (0) instead of &end.
1313 * core.c (core_add_stack, core_add_data): Was not handling case
1314 where bss/stack is grown across the current end-of-{bss,stack}.
1316 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
1318 * system.c (system_call): Fix SYS_break - was aligning bss to a
