128 | ||
129 | * ppc-instructions (model data, model_busy): Rather than using a | |
130 | bit mask for the busy units, just use a char array. Also, only | |
131 | support 2 function units an insn can use, rather than a loop. | |
132 | ||

134 | ||
0bcce7d3 MM |
135 | * table.c (table_entry_read): Move setting entry->line_nr to after |
136 | the model specific fields so the line numbers for the annex are | |
137 | correct. | |
138 | ||
4220dcd6 MM |
139 | * cpu.c (cpu_{create,init,halt}): Check for WITH_MODEL_ISSUE |
140 | before calling the model functions. | |

184 | ||
867b7168 MM |
185 | * mon.c (mon_issue): Pass processor argument to model_issue. |
186 | ||
84bbbc35 MM |
187 | * Makefile.in: Delete all function unit support, since the newer |
188 | table driven model support replaces it. | |
189 | * cpu.{c,h}: Ditto. | |

212 | ||
80948f39 MM |
213 | Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com> |

239 | Tue Nov 14 04:47:25 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
240 | ||
fe439e0f | 241 | * Makefile.in (devices.o, main.o): Update dependency. |

253 | Mon Nov 13 09:14:13 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
254 | ||
255 | * igen.c ({insn,model}_table_fields): Spell mnemonic correctly. | |
256 | (gen_itable_h,itable_c_insn): Ditto. | |
257 | (model support): Move model support around, add support for | |
258 | model-data, model-internal. Use annex field for model-macros | |
259 | now. | |
260 | ||
261 | * configure.in (--enable-sim-inline): If --enable-sim-inline=no, | |
262 | also define INLINE as nothing. | |
263 | * configure: Regenerate. | |
264 | ||
265 | * std-config.h (INLINE): Rather than nuking INLINE, only define it | |
266 | as __inline__ if any of the INLINE flags are non-zero. | |
267 | ||
268 | * options.c (print_options): Print out WITH_XOR_ENDAIN. | |
269 | ||
270 | Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au> | |
271 | ||
272 | * ppc-instructions (rfi): Add missing code. | |
273 | ||
274 | * cpu.c (cpu_get_time_base): Fix calculation of current value of | |
275 | time base register. | |
276 | ||
277 | * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing | |
278 | m[tf]tb with m[tf]spr. | |
279 | ||
280 | * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing | |
281 | lower word. | |
282 | ||
283 | Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au> | |
284 | ||
285 | * std-config.h (INLINE, STATIC_INLINE): Was being set to static | |
286 | inline.. Only problem being that with ppc-opcode-simple this gave | |
287 | it the chance to inline all the idecode functions with potentially | |
288 | disasterous results on a 16mb PC. For moment hobble INLINE. | |
289 | ||
290 | * configure.in, std-config.h (WITH_SMP): Make that 5 processors by | |
291 | default ... | |
292 | ||
293 | * configure.in: Tweek flags passed to gcc for --with-sim-warnings. | |
294 | Firstly make them errors and secondly remove the options gcc-245 | |
295 | doesn't reconize. | |
296 | ||
297 | Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au> | |
298 | ||
299 | * misc.c (zalloc), cpu.c (cpu_init), devices | |
300 | (console_io_read_buffer_callback, icu_io_read_buffer_callback, | |
301 | vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset), | |
302 | sim_calls.c (zalloc) : replace bzero() with memset(). | |
303 | ||
304 | * emul_netbsd.c (write_direntries), psim.c (psim_read_register, | |
305 | psim_write_register): replace bcopy() with memcpy(). | |
306 | ||
307 | Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> | |
308 | ||
309 | * configure.in: for --disable-sim-inline (--enable-sim-inline=no), | |
310 | force DEFAULT_INLINE to 0 rather then trusting the std | |
311 | configuration. | |
312 | ||
313 | Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> | |
314 | ||
315 | * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix | |
316 | generation of switch entries in tables - treat the same as | |
317 | cracking/semantic functions. | |
318 | ||
319 | * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation | |
320 | of a boolean switch statement (field zero or non-zero). | |
321 | ||
322 | * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the | |
323 | switch/table generation ability of igen. | |
324 | ||
325 | * igen.c (idecode_switch_leaf): Fix code output when a switch | |
326 | statement needs to look up a table. | |
327 | ||
328 | * igen.c (idecode_declare_if_switch): New function called from | |
329 | gen_idecode_c - need to declare any idecode switch functions | |
330 | before they are used in idecode tables. | |
331 | ||
332 | * igen.c (lf_print_c_cracker_function, idecode_crack_leaf, | |
333 | idecode_crack_insn): Add is_inline_function argument to code | |
334 | printing cracker functions which indicates if STATIC_IDECODE or | |
335 | STATIC_INLINE_IDECODE should be used for definition. For | |
336 | idecode_crack_insn (which implies not duplicating/expanding) don't | |
337 | declare function as inline - we assume that the only time this is | |
338 | code is generated is when things are being tested. For | |
339 | idecode_crack_leaf, make static (instead of INLINE) if the | |
340 | instructions parent is a table as function will always be called | |
341 | via a table. | |
342 | ||
343 | * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not | |
344 | STATIC_INLINE_IDECODE. Only the outermost idecode switch will be | |
345 | called directly, all others are called via a table. | |
346 | ||
347 | * igen.c (lf_print_semantic_function_header, semantics_h_leaf, | |
348 | semantics_h_insn, semantics_h_function, | |
349 | lf_print_c_semantic_function, semantics_c_function): Add | |
350 | is_inline_function argument to lf_print_semantic_function_header | |
351 | to indicate if an inline or static function declaration/definition | |
352 | should be output. Depending on situtation call accordingly: | |
353 | functions (not instruction semantic routines) are always inline; | |
354 | Semantic routines are made inline when there is no icache (cache | |
355 | will contain the function address) and are duplicating (see above) | |
356 | and the parent of the instruction is a switch statement. | |
357 | ||
358 | * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC | |
359 | and moved to insn_table_find_opcode_field. | |
360 | ||
361 | * table.c (table_open): Fix typo (nr_model_fields vs nr_fields). | |
362 | ||
363 | * igen.c (model_c_insn): Suggestion - document the name of the | |
364 | instruction on each line of the instruction model table. | |
365 | ||
366 | Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au> | |
367 | ||
368 | * emul_netbsd.c (do_ioctl): Cleanup compilation. | |
369 | ||
370 | * sim_callbacks.h (__attribute__): Only define if not defined (was | |
371 | already defined on NetBSD host). | |
372 | ||
373 | Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> | |
374 | ||
375 | * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New | |
376 | macro, indicates if the PowerPC's horrible XOR endian mode should | |
377 | be suported. Add to configure and make. | |
378 | ||
379 | * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c | |
380 | (vm_instruction_map_read): If XOR endian, xor the address | |
381 | with a value from an xor table (indexed by size of access). | |
382 | ||
383 | * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context): | |
384 | set up xor table to xor if there is a conflict between the | |
385 | CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move | |
386 | check of suported change of endian mode from cpu.c to vm.c. | |
387 | ||
388 | * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer): | |
389 | Hopefully added correct hack to handle XOR endian mode. | |
390 | ||
391 | FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates | |
392 | little endian mode, the model accepts miss aligned transfers. | |
393 | ||
394 | FIXME: Need to create an `init' device that, during | |
395 | initializatioin for XOR mode, it mushes (XOR address) all the dma | |
396 | data before passing it on to the core for storage. Just like the | |
397 | real thing really. | |

826 | * Makefile.in: Uncomment built file dependencies. |
827 | ||
c494cadd MM |
828 | * configure.in: Rewrite --enable-sim switch handling to use the |
829 | autoconf builtins so it works correctly if the configure or | |
830 | Makefile.in files are modified and make decides to rebuild | |
831 | Makefile. Also document all of the --enable-sim switches | |
832 | supported. Check whether getrusage and sys/resource.h are | |
833 | supported. | |
834 | * config.in: Regenerate. | |
835 | * configure: Regenerate. | |
836 | * Makefile.in: Add support for all of the variables set with | |
837 | --enable-sim switches. | |
838 | ||
839 | * Makefile.in (clean): make clean now removes all built sources as | |
840 | well. | |
841 | ||
842 | * cpu.c: Use HAVE_STRING_H, HAVE_STRINGS_H, HAVE_UNISTD_H, | |
843 | HAVE_TIME_H, HAVE_SYS_TIMES_H, HAVE_SYS_RESOURCE_H defined in | |
844 | the generated config.h. | |

a983c8f0 MM |
859 | * main.c (main): Call psim_print_info with verbose == 2. |
860 | ||
861 | * mon.c (mon_print_info): Align the cpu number and number of | |
862 | instructions fields. Do not print an instruction category if the | |
c494cadd MM |
863 | CPU did not execute any of those instructions. Print out number |
864 | of reads and writes. If getrusage is supported, print out number | |
865 | of simulated instructins per second. | |
a983c8f0 MM |

a983c8f0 MM |
871 | |
872 | * std-config (INLINE_DEVICE_TREE): Don't inline either of | |
873 | device_tree.c or devices.c. There is no significant gain. | |
874 | ||
875 | * configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and | |
876 | IGEN_ICACHE macro. | |
877 | ||

a983c8f0 MM |
879 | |
880 | * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add | |
881 | functions to convert between target and igen internal bit numbers. | |
882 | Make IO go through these functions. Add -b (bit size) and -h (high | |
883 | bit nr) options to igen. Typical usage would be: ./igen -b 16 -h | |
884 | 15 for a 16 bit instruction format with the msb given a number 15. | |

891 | |
892 | * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h, | |
893 | debug.c: Add tracing of load/store unit (virtual) with -t | |
894 | load-store. | |

a983c8f0 MM |
897 | |
898 | * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does | |
899 | not include things such as the time base and events. | |
900 | ||
901 | * interrupt.c, sim_calls.c, cpu.h, vm.c, configure.in: Add UEA to | |
902 | all environment switches for above. | |
903 | ||
904 | * psim.c (psim_create): ditto - new device tree node name is | |
905 | /options/environment-architecture with values user, virtual and | |
906 | operating. | |

a983c8f0 MM |
909 | |
910 | * ppc-opcode-stupid: Third example of use of opcode table - this | |
911 | one expands all mtspr/mfspr and branch instructions. Appears to | |
912 | give about a 10% gain in performance if everything enabled. Also | |
913 | takes about 150mb of swap to build. | |

916 | ||
917 | * emul_netbsd.c (do_exit): Print arguments and close parenthesis | |
918 | if tracing, since exit doesn't go through emul_exit_call. | |
919 | (do_read): Print arguments if tracing. | |

936 | the directory prefix from a file. | |
937 | * filter_filename.h: New include file to declare filter_filename. | |
938 | ||
939 | * debug.h: Include filter_filename.h. | |
940 | (TRACE,DTRACE,ERROR): Use filter_filename on __FILE__. | |
941 | ||
942 | * misc.h: Include filter_filename.h. | |
943 | (ASSERT): Use filter_filename on __FILE__. | |
944 | ||
945 | * igen.c (lf_print_my_prefix): Use filter_filename on the filename | |
946 | argument. | |
947 | ||
948 | * Makefile.in: Add filter_filename support. | |
949 | ||
950 | * ppc-instructions (dcbi, icbi): Make these NOPs rather than | |
951 | invalid instructions. | |
952 | ||
953 | * configure.in: Add support for more --enable-sim-* switches. | |
954 | Use config.make and config.hdr to write to Makefile and config.h | |
955 | respectively. Don't rewrite Makefile, just append to it. | |
956 | * configure: Regenerate. | |
957 | * config.{make,hdr}: New shell scripts. | |
958 | ||
959 | * Makefile.in: Remove all variables set by configure.in. | |
960 | (psim.o): Depend on $(BUILT_SRC) also. | |
961 | ||
962 | * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an | |
963 | integer, use 0, not NULL. | |
964 | ||

965 | Tue Oct 31 15:20:04 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
966 | ||
967 | * configure.in: Add support for --enable-sim-inline, | |
968 | --enable-sim-bswap, --enable-sim-cflags, --enable-sim-complex, | |
969 | --enable-sim-switch, --enable-sim-duplicate, --enable-sim-filter, | |
970 | and --enable-sim-endian switch to control various Makefile | |
971 | variables. | |
972 | * configure: Regenerate from configure.in. | |
c143ef62 MM |
973 | * Makefile.in: Add various Make variables that the various |
974 | switches alter. | |
4b935ed4 MM |
975 | |
976 | * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC | |
977 | and optimizing by default. | |
978 | ||

5b4d72dd MM |
980 | |
981 | * bits.h (ROTL32, ROTL64): Were functions, made them macros, now | |
982 | make them functions again. Appears 2.6.3 is confused by just a | |
983 | macro. | |
984 | ||
c143ef62 | 985 | Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au> |
5b4d72dd MM |
986 | |
987 | * ppc-endian.c (SWAP_8): Fix 8 byte swap! | |
988 | ||
989 | * psim.c (psim_create): Not correctly checking that runtime | |
990 | configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT | |
991 | matched the compiled in ones. | |
992 | ||
993 | * debug.h (ITRACE), igen.c: Tidy up more tracing flags - | |
994 | trace_semantics is now different to trace_idecode, the former | |
995 | checks the cache. | |
996 | ||
c143ef62 | 997 | Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au> |
5b4d72dd MM |

999 | * ppc-instructions (mtsrin): Missing instruction | |
1000 | * ppc-instructions (mfsrin): Missing instruction | |
1001 | * ppc-instructions (eieio): Missing instruction | |
1002 | ||

5b4d72dd MM |
1004 | |
1005 | * build-psim: New shell script - see internals for usage, | |
1006 | simplifies the process of building custom simulators. | |
1007 | ||
c143ef62 | 1008 | Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au> |
5b4d72dd MM |
1009 | |
1010 | * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the | |
1011 | INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2. | |
1012 | Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE | |
1013 | DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on | |
1014 | the instruction or data critical paths. | |
1015 | ||
1016 | * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but | |
1017 | not on critical path. | |
1018 | ||
1019 | * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from | |
1020 | the inclusion of device_tree.c/emul_generic.c. | |
1021 | ||
c143ef62 | 1022 | Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au> |
5b4d72dd MM |
1023 | |
1024 | * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace | |
1025 | system.[hc]. Start of suport for multiple emulations and | |
1026 | emulation state (os_emul object). | |
1027 | ||
1028 | * emul_generic.[hc]: Start of code to implement proper system call | |
1029 | tracing (from spy). | |
1030 | ||
c143ef62 | 1031 | Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au> |
5b4d72dd MM |
1032 | |
1033 | * cpu.h, cpu.c (cpu_init): New function, zero the registers before | |
1034 | the processor is started. Fixes problem of registers being | |
1035 | undefined when restarting from within gdb. | |
1036 | ||
1037 | * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the | |
1038 | instruction cache (if present). Fixes problem of cpu caching gdb | |
1039 | breakpoint instructions. | |
1040 | ||
1041 | FIXME: PSIM sometimes aborts calling error(), it should instead | |
1042 | call sim_error() say which takes care of housekeeping such as | |
1043 | saving the CIA before calling error. | |
1044 | ||
1045 | * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is | |
1046 | used when restarting a simulation because the latter has the | |
1047 | unwanted side effect (well I as a kernel hacker think it is) of | |
1048 | performing an isync when the instruction stream doesn't contain | |
1049 | one. | |
1050 | ||
c143ef62 | 1051 | Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au> |
5b4d72dd MM |
1052 | |
1053 | * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance | |
1054 | monitoring module. Counts both instructions issued and | |
1055 | load/stores. | |
1056 | ||
1057 | * NOTE: mon does not contain to count instruction loads as this | |
1058 | information is already available from the mon_issue() hook. | |
1059 | ||
1060 | * FIXME: mon doesn't have access to register usage information. | |
1061 | This is needed if the user wants to monitor things like register | |
1062 | stalls. | |
1063 | ||
1064 | * igen.c (lf_print_c_semantic), vm_n.h: Add counting code. | |
1065 | ||
1066 | * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach | |
1067 | a common monitor to each of the cpus. Delete | |
1068 | cpu_increment_number_of_insns() and cpu_get_number_of_insns() | |
1069 | replaced by copied code in mon.[hc]. | |

5b4d72dd MM |
1072 | |
1073 | * sim_calls.c, main.c, psim.c (psim_create): always create | |
1074 | `WITH_SMP' cpus. The actual number of CPU's active in a | |
1075 | simulation run is taken from the device node: /init/smp (an | |
1076 | integer). WITH_SMP changed to 2 (remember to put it back to 0). | |
1077 | ||

5b4d72dd MM |
1079 | |
1080 | * system.c: More system call emulation. If code appears NetBSD | |
1081 | specific, make conditional to being compiled on a NetBSD system | |
1082 | (sigh). | |
1083 | ||
c143ef62 | 1084 | Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au> |
5b4d72dd MM |
1085 | |
1086 | * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new), | |
1087 | lf.[ch](new), table.[ch](new): Split into two generators - igen | |
1088 | that outputs the instruction tables and dgen that outputs the spr | |
1089 | tables. Add -f (filter out) flag to igen to filter out certain | |
1090 | instructions (ex 64 bit ones) from the created tables. Include | |
1091 | $(LIBIBERTY_LIB) in link options in case host lacks some libc | |
1092 | functions. | |
1093 | ||
1094 | * NOTE: igen, since it was originally written for the | |
1095 | PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}. | |
1096 | ||
1097 | * Makefile.in, std-config.h, ppc-cache-rules(new), | |
1098 | ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create | |
1099 | cache-rule and opcode-rule tables from macros found std-config.h. | |
1100 | Delete corresponding macro's from std-config.h. | |
1101 | ||
1102 | * FIXME: under this new igen scheme, when playing around with igen | |
1103 | options, you'll find that depenencies don't work very well. | |
1104 | ||
1105 | * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output | |
1106 | an table of all the instructions. Code to output a type | |
1107 | enumerating all the instructin names. | |
1108 | ||
1109 | * igen.c(lf_print_c_semantic): Move call to increment instruction | |
1110 | counter so that it occures _after_ the instruction has been fully | |
1111 | validated, was double counting illegal/invalid instructions. Add | |
1112 | conditional so only compiled in when WITH_PROFILE enabled (enabled | |
1113 | by default). | |
1114 | ||
1115 | * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include | |
1116 | itable.h, count individual instruction types not just total, | |
1117 | adjust reporting functions to output this. | |
1118 | ||
1119 | * ppc-instructions (64 bit Load Doubleword with Update Indexed): | |
1120 | Had 32./ instead of 31./ | |
1121 | ||
1122 | * ppc-instructions (64 bit Store Double Word Conditional Indexed): | |
1123 | bitrot - updated to use newer CR register operators. | |
1124 | ||
1125 | * ppc-instructions (64bit Floating Convert from Integer | |
1126 | Doubleword): Correct call to Round_Float(). | |

5b4d72dd MM |

1130 | * basics.h: #include "sim_callbacks.h" earlier so that its | |
1131 | prototypes are declared in all other header files. | |
1132 | ||
1133 | * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update | |
1134 | doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into | |
1135 | bits.h. | |
1136 | ||
1137 | * FIXME: the bits.h/bits.c macro's should be replaced with | |
1138 | (inline) c functions. | |
1139 | ||
1140 | * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*): | |
1141 | Add size of buffer argument to functions writing a string into a | |
1142 | buffer. Check for buffer overflow. | |
1143 | ||

5b4d72dd MM |
1145 | |
1146 | * devices.h, devices.c, debug.h, debug.c: add macro's for tracing | |
1147 | of each device. Make parameter names consistent so macros work. | |
1148 | Use macro's in device functions. | |
1149 | ||
1150 | * device_tree.c, devices.h, devices.c: include path to device in a | |
1151 | devices node when creating it. | |
1152 | ||
1153 | * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'. | |
1154 | ||
1155 | * core.c: add tracing of core-device, adjust parameter names in | |
1156 | core functions to be consistent with those in devices*. | |
1157 | ||

5b4d72dd MM |
1159 | |
1160 | * debug.h, debug.c (trace_option): New function. Parses the trace | |
1161 | option, updating the trace array. | |
1162 | ||
1163 | * debug.h, debug.c (trace_usage): New function. Outputs the list | |
1164 | of all possible trace options. | |
1165 | ||
1166 | * sim_calls.c (sim_open), main.c (main): Use new trace_option() to | |
1167 | parse trace options specified with the simpler -t flag. Adjust | |
1168 | usage. | |
1169 | ||
1170 | * FIXME: basic parsing of command line options is still duplicated | |
1171 | by main.c and sim_calls.c | |

1175 | * Makefile.in (clean): Delete *.i and *.out files. |
1176 | ||
22ddef46 MM |
1177 | * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP |
1178 | macros for either assignment or return. Fix SWAP_8 to use a | |
1179 | union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now. | |
1180 | (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs | |
1181 | that hardwired swapping on/off, let optimizer delete dead code. | |
1182 | ||
1183 | * main.c (main): Add printf that we caught a signal and print out | |
1184 | the failing address. | |

1202 | ||
1203 | * gen.c, ppc-instructions, psim.c: Fix code for generating | |
1204 | cracking instruction cache. Delete the code that cached just the | |
1205 | result from doing an instruction lookup - this ran slower than no | |
1206 | cache at all. | |

1211 | ||
a1fe883f MM |
1212 | * debug.h (ppc_trace): Rename from trace, to avoid a conflict with |
1213 | TCL when gdb is linked with the simulator. | |
1214 | * debug.c (ppc_trace): Ditto. | |
1215 | * sim_calls.c (sim_open): Change trace -> ppc_trace. | |

1229 | * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for |
1230 | 2, 4, and 8 bytes. | |
1231 | (ENDIAN_N): If both target and host byte orders are known, don't | |
1232 | bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER. | |
1233 | ||
1234 | * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0 | |
1235 | to allow target specific H2T_n/T2H_n macros to be used. | |
1236 | (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is | |
1237 | non-zero, redefine the htonl/ntohl macros to use the BSWAP instead | |
1238 | of the 3 instruction sequence that runs on 386s. | |
1239 | ||
1240 | * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if | |
1241 | specified on the compile line. | |
1242 | (WITH_BSWAP): If not defined, define as 0. | |
1243 | ||
8e20a3ac MM |
1244 | * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add |
1245 | default inline support. Pass INLINE_CFLAGS when compiling. | |
1246 | ||
1247 | * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not | |
1248 | INLINE_DEVICES since GCC doesn't like inline functions that | |
1249 | accept variable arguments. | |

8e20a3ac MM |
1269 | |
1270 | * ppc-instructions: Initial cut of floating point suport added. | |
1271 | Of note include - use of host IEEE floating point instructions, | |
1272 | use of PowerPC manual pseudo code to handle the FPSCR. It is not | |
1273 | currently a pretty sight. | |
1274 | ||
1275 | * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c: | |
1276 | merge into core.h, core.c, core_n.h. The type memory_map replaced | |
1277 | with core_map. This removes a level of pointer indirection when | |
1278 | translating an address. | |
1279 | ||
1280 | * memory_map.h, memory_map.c, memory_map_n.h: delete. | |
1281 | ||
1282 | * Makefile.in et.al (sorry): tweek to use new core, core_map and | |
1283 | core.h. | |

1287 | * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to | |
1288 | most of the other functions in sim_calls.c. | |
1289 | ||
1290 | * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in: | |
1291 | Add macros to better cover up `generic' code. Makes it possible | |
1292 | to step through the generic code! | |
1293 | ||
1294 | * vm.c, vm_n.h, Makefile.in: ditto | |
1295 | ||

8e20a3ac MM |
1297 | |
1298 | * devices.h, devices.c, memory_map.h, memory_map.c: Changed | |
1299 | callback interface so that there is a read/write buffer but no | |
1300 | read/write_word. VEA default memory read/write handler sometimes | |
1301 | couldn't resolve an access and of those some were for a memory | |
1302 | fault and some were because gdb was making a bogus request. | |
1303 | ||
1304 | * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c: | |
1305 | eliminate transfer_mode (raw or cooked) parameter from read/write | |
1306 | buffer. | |

1314 | |
1315 | * psim.c, device_tree.h, device_tree.c, devices.c (printd_*, | |
1316 | scand_*): new functions to parse/print fields in device names | |
1317 | while hiding any machine dependency. | |
1318 | ||
1319 | * devices.c, psim.c: Change the stack init code so that it is | |
1320 | handled by a device. Arguments passed across using a device ioctl | |
1321 | (hack). | |
1322 | ||
1323 | * devices.h, devices.c: device ioctl callback changed to allow a | |
1324 | variable number of arguments. This gives greater flexability and | |
1325 | greater chance of bugs. | |
1326 | ||

1330 | variable argument use. | |
1331 | ||

1333 | versions of make not handling files being created as side-effects. | |
1334 | ||
1335 | * gen.c (lf_open): Add -n (real_file_name) option. Specifies an | |
1336 | alternative file name to use in output files for things like #line | |
1337 | macros. | |
1338 | ||
1339 | Makefile.in (tmp-gencode): Use gen -n so that debug info is | |
1340 | correct. | |
1341 | ||
1342 | * Makefile.in (TARGETLIB): Use this instead of libsim.a in the | |
1343 | Makefile. | |

1541 | ||
1542 | * devices.c, device_tree.c: Added code that provides a simple | |
1543 | illustration of how an interrupt control device could be | |
1544 | implemented. | |
