400 | ||
401 | Tue Dec 19 13:00:11 1995 Andrew Cagney <cagney@highland.com.au> | |
402 | ||
403 | * emul_chirp.c (chirp_emul_exit): Full out call. | |
404 | ||
405 | * device_table.c (htab_map_page): Wasn't handling byte swap when | |
406 | creating entries in the hash table. | |
407 | ||
408 | * device.c (device_tree_find_node): Allow primative wild-card match | |
409 | of device names with the path. | |
410 | ||
411 | FIXME: As mentioned earlier, the device stuff needs work to bring | |
412 | it into line with OpenBoot. Part of this work is rewriting the | |
413 | find_node function so that it behaves as specified in p1275. | |
414 | ||
415 | Mon Dec 18 19:58:56 1995 Andrew Cagney <cagney@highland.com.au> | |
416 | ||
417 | * emul_chrp.c (chirp_emul_write, chirp_emul_finddevice): add | |
418 | better tracing. | |
419 | ||
420 | * emul_chrp.c: Change return type of emul functions to int. Emul | |
421 | functions either return -1 or zero so unsigned was a bit | |
422 | dangerous. | |
423 | ||
424 | * inline.h (*), igen.c, dgen.c, *: Update INLINE macros so that | |
425 | they are paramaterised with the type of the function. Gets around | |
426 | the problem of `static' needing to come first with `attribute' | |
427 | comming last. Format declarations and definitions so that emacs | |
428 | doesn't get confused. | |
429 | ||
430 | Fri Dec 15 17:06:44 1995 Andrew Cagney <cagney@highland.com.au> | |
431 | ||
432 | * std-config.h (PSIM_INLINE): Add missing inline configuration | |
433 | control for the main loop. | |
434 | ||
435 | * mon.c (mon_print_info): If monitoring disabled still print out | |
436 | the number seconds used. | |
437 | ||
438 | * psim.c (run_until_stop): Don't monitor the cache misses when | |
439 | monitoring is disabled. | |
440 | ||
441 | * configure.in (sim_mon, sim_monitor): Correct typo - sim_mon -> | |
442 | sim_monitor for shell variable (or should that have been the other | |
443 | way around?). | |
444 | ||
445 | * vm.c (vm_synchronize_context): Fix wrong test for unsuported | |
446 | change in endian-mode. | |
447 | ||
448 | * std-config.h (WITH_REGPARM), inline.h (IDECODE_INLINE, | |
449 | SEMANTICS_INLINE): Add -DWITH_REGPARM=<n> option. Enables the | |
450 | __attribute__((__regparm(WITH_REGPARM))) for some functions. | |
451 | configure with --enable-sim-cflags="-DWITH_REGPARAM=3" (say). | |
452 | Unfortunatly it tickles a bug (gcc?) and can't be used. | |
453 | ||

464 | ||
465 | * emul_netbsd.c (emul_netbsd_create): Deal with new BFD that | |
466 | changed how big/little endian support is recorded, while remaining | |
467 | compatible with the old BFD with #ifdefs. | |
468 | * emul_chirp.c (emul_chirp_create): Ditto. | |

481 | ||
482 | * lf.c (lf_print_function_type): New function. Munges a function | |
483 | type so that the prefix (eg INLINE...) is inserted after the type | |
484 | but before any `*'. | |
485 | ||
486 | * igen.c: Change to output functions using this. | |
487 | ||

505 | ||
506 | * std-config.h (CPU_INLINE), cpu.h, inline.h, inline.c: make cpu.h | |
507 | inline always. | |

519 | error? | |
520 | ||
521 | Tue Dec 5 11:56:14 1995 Andrew Cagney <cagney@highland.com.au> | |
522 | ||
523 | * ppc-instructions (ppc_nr_mtcrf_crs, ppc_branch_conditional_name, | |
524 | ppc_function_unit_name): Simplify by declaring these arrays as | |

526 | ||
527 | Tue Dec 5 00:45:34 1995 Andrew Cagney <cagney@highland.com.au> | |
528 | ||
529 | * sim_calls.c (sim_create, sim_load), main.c (main), psim.c: Pass | |
530 | an options device into psim_create() so that options can be merged | |
531 | into the tree. | |
532 | ||
533 | * device.c (*add*): Change semantics so the add functions only add | |
534 | when the new device (or property) doesn't already exist. This | |
535 | allows merging of options and data. | |
536 | ||
537 | Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@highland.com.au> | |
538 | ||
539 | * Makefile.in (BASICS_H): Didn't include basics.h in the list of | |
540 | header files to depend on. | |
541 | ||
542 | Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@highland.com.au> | |
543 | ||
544 | * std-config.h: (*_MODULE): Extend the <module>_inline macro's so | |
545 | that they also allow control over static functions. Rewrite | |
546 | document to reflect this. | |
547 | ||
548 | * std-config.h: (INLINE): Simplify definition, the above and | |
549 | earlier changes to igen.h eliminate the need to be defensive about | |
550 | enabling the inline of static functions. | |
551 | ||
552 | * std-config.h: (SIM_ENDIAN_INLINE, BITS_INLINE): Document limited | |
553 | suport for inlineing of modules for all callers. Adjust relevant | |
554 | macro's so that DEFAULT_INLINE will enable this. | |
555 | ||
556 | * basics.h: Re-order #includes and definitions so that c-code for | |
557 | basic include files does not call functions delcared in later | |
558 | #includes. | |
559 | ||
560 | * basics.h (__attribute__), sim_callbacks.h: Move attribute macro | |
561 | to basics.h and add hack (include <stdio.h>) to try and bring that | |
562 | and other possible conflicting macros into scope much earler. | |
563 | ||
564 | * sim-endian.h,c (SIM_ENDIAN_INLINE) bits.h,c (BITS_INLINE): | |
565 | Change to use the updated inline definitions. If enabled | |
566 | immediatly include the corresponding c-code so that it will inline | |
567 | for all modules. | |
568 | ||
569 | * inline.h, inline.c (SIM_ENDIAN_INLINE, BITS_INLINE): Remove | |
570 | these cases, moved to module specific header files. | |

584 | instead of &. | |
585 | ||
586 | * sim-endian.h (SWAP_N), sim-endian-n.h, sim-endian.c: How | |
587 | embarasing - fix yet another bug in the swap code! Simplify | |

618 | device_table.c: Add the concept of a device instance and operators | |
619 | on these instances - corresponds to ihandle in OpenBoot speak. | |

627 | associated code. | |
628 | ||
629 | * os_emul.h, os_emul.c, emul_generic.h: Correct and fill an | |
630 | os_emul interface. | |
631 | ||
632 | * os_emul.c, emul_bugapi.h, emul_bugapi.c, Makefile.in: Add | |
633 | preliminary hooks for a kernel mode rom emulation. | |
634 | ||

636 | pass object identifiers (capabilities?) to/from the simulated code | |
637 | (for instance the phandle in OpenBoot). The cap object is able to | |
638 | check/map between internal and external (target program) | |

656 | os_emul_system_call function(). | |
657 | ||
658 | * emul_netbsd.c: Update to interface to generic emulation. Since | |
659 | all its functions are called via a table don't worry about any | |
660 | inline. | |
661 | ||
662 | * emul_generic.h, emul_generic.c, spa-*(delete): Remove references | |
663 | and code for spa, no longer to be used. | |
664 | ||

670 | ||
671 | * debug.h, debug.c: pte trace is made redundant by htab trace, | |
672 | delete it. Add vm to list of options. Simplify tracing output so | |
673 | lines are not as long. | |
674 | ||

735 | ||
736 | * std-config.h (MODEL_INLINE): If not defined, define as 1 if | |

755 | #undef if -R. | |
756 | (lf_print_c_extraction): If -R and this is semantics, emit names | |

876 | * mon.c (mon_issue): Pass processor argument to model_issue. |
877 | ||
84bbbc35 MM |
878 | * Makefile.in: Delete all function unit support, since the newer |
879 | table driven model support replaces it. | |

898 | ||
899 | * ppc-instructions: Move branch tracing to the actual branch | |

944 | Mon Nov 13 09:14:13 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
945 | ||
946 | * igen.c ({insn,model}_table_fields): Spell mnemonic correctly. | |
947 | (gen_itable_h,itable_c_insn): Ditto. | |
948 | (model support): Move model support around, add support for | |
949 | model-data, model-internal. Use annex field for model-macros | |
950 | now. | |
951 | ||
952 | * configure.in (--enable-sim-inline): If --enable-sim-inline=no, | |
953 | also define INLINE as nothing. | |
954 | * configure: Regenerate. | |
955 | ||
956 | * std-config.h (INLINE): Rather than nuking INLINE, only define it | |
957 | as __inline__ if any of the INLINE flags are non-zero. | |
958 | ||
959 | * options.c (print_options): Print out WITH_XOR_ENDAIN. | |
960 | ||
961 | Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au> | |
962 | ||
963 | * ppc-instructions (rfi): Add missing code. | |
964 | ||
965 | * cpu.c (cpu_get_time_base): Fix calculation of current value of | |
966 | time base register. | |
967 | ||
968 | * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing | |
969 | m[tf]tb with m[tf]spr. | |
970 | ||
971 | * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing | |
972 | lower word. | |
973 | ||
974 | Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au> | |
975 | ||
976 | * std-config.h (INLINE, STATIC_INLINE): Was being set to static | |
977 | inline.. Only problem being that with ppc-opcode-simple this gave | |
978 | it the chance to inline all the idecode functions with potentially | |
979 | disasterous results on a 16mb PC. For moment hobble INLINE. | |
980 | ||
981 | * configure.in, std-config.h (WITH_SMP): Make that 5 processors by | |
982 | default ... | |
983 | ||
984 | * configure.in: Tweek flags passed to gcc for --with-sim-warnings. | |
985 | Firstly make them errors and secondly remove the options gcc-245 | |
986 | doesn't reconize. | |
987 | ||
988 | Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au> | |
989 | ||
990 | * misc.c (zalloc), cpu.c (cpu_init), devices | |
991 | (console_io_read_buffer_callback, icu_io_read_buffer_callback, | |
992 | vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset), | |
993 | sim_calls.c (zalloc) : replace bzero() with memset(). | |
994 | ||
995 | * emul_netbsd.c (write_direntries), psim.c (psim_read_register, | |
996 | psim_write_register): replace bcopy() with memcpy(). | |
997 | ||
998 | Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> | |
999 | ||
1000 | * configure.in: for --disable-sim-inline (--enable-sim-inline=no), | |
1001 | force DEFAULT_INLINE to 0 rather then trusting the std | |
1002 | configuration. | |
1003 | ||
1004 | Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> | |
1005 | ||
1006 | * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix | |
1007 | generation of switch entries in tables - treat the same as | |
1008 | cracking/semantic functions. | |
1009 | ||
1010 | * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation | |
1011 | of a boolean switch statement (field zero or non-zero). | |
1012 | ||
1013 | * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the | |
1014 | switch/table generation ability of igen. | |
1015 | ||
1016 | * igen.c (idecode_switch_leaf): Fix code output when a switch | |
1017 | statement needs to look up a table. | |
1018 | ||
1019 | * igen.c (idecode_declare_if_switch): New function called from | |
1020 | gen_idecode_c - need to declare any idecode switch functions | |
1021 | before they are used in idecode tables. | |
1022 | ||
1023 | * igen.c (lf_print_c_cracker_function, idecode_crack_leaf, | |
1024 | idecode_crack_insn): Add is_inline_function argument to code | |
1025 | printing cracker functions which indicates if STATIC_IDECODE or | |
1026 | STATIC_INLINE_IDECODE should be used for definition. For | |
1027 | idecode_crack_insn (which implies not duplicating/expanding) don't | |
1028 | declare function as inline - we assume that the only time this is | |
1029 | code is generated is when things are being tested. For | |
1030 | idecode_crack_leaf, make static (instead of INLINE) if the | |
1031 | instructions parent is a table as function will always be called | |
1032 | via a table. | |
1033 | ||
1034 | * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not | |
1035 | STATIC_INLINE_IDECODE. Only the outermost idecode switch will be | |
1036 | called directly, all others are called via a table. | |
1037 | ||
1038 | * igen.c (lf_print_semantic_function_header, semantics_h_leaf, | |
1039 | semantics_h_insn, semantics_h_function, | |
1040 | lf_print_c_semantic_function, semantics_c_function): Add | |
1041 | is_inline_function argument to lf_print_semantic_function_header | |
1042 | to indicate if an inline or static function declaration/definition | |
1043 | should be output. Depending on situtation call accordingly: | |
1044 | functions (not instruction semantic routines) are always inline; | |
1045 | Semantic routines are made inline when there is no icache (cache | |
1046 | will contain the function address) and are duplicating (see above) | |
1047 | and the parent of the instruction is a switch statement. | |
1048 | ||
1049 | * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC | |
1050 | and moved to insn_table_find_opcode_field. | |
1051 | ||
1052 | * table.c (table_open): Fix typo (nr_model_fields vs nr_fields). | |
1053 | ||
1054 | * igen.c (model_c_insn): Suggestion - document the name of the | |
1055 | instruction on each line of the instruction model table. | |
1056 | ||
1057 | Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au> | |
1058 | ||
1059 | * emul_netbsd.c (do_ioctl): Cleanup compilation. | |
1060 | ||
1061 | * sim_callbacks.h (__attribute__): Only define if not defined (was | |
1062 | already defined on NetBSD host). | |
1063 | ||
1064 | Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> | |
1065 | ||
1066 | * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New | |
1067 | macro, indicates if the PowerPC's horrible XOR endian mode should | |
1068 | be suported. Add to configure and make. | |
1069 | ||
1070 | * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c | |
1071 | (vm_instruction_map_read): If XOR endian, xor the address | |
1072 | with a value from an xor table (indexed by size of access). | |
1073 | ||
1074 | * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context): | |
1075 | set up xor table to xor if there is a conflict between the | |
1076 | CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move | |
1077 | check of suported change of endian mode from cpu.c to vm.c. | |
1078 | ||
1079 | * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer): | |
1080 | Hopefully added correct hack to handle XOR endian mode. | |
1081 | ||
1082 | FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates | |
1083 | little endian mode, the model accepts miss aligned transfers. | |
1084 | ||
1085 | FIXME: Need to create an `init' device that, during | |
1086 | initializatioin for XOR mode, it mushes (XOR address) all the dma | |
1087 | data before passing it on to the core for storage. Just like the | |
1088 | real thing really. | |
1089 | ||
1090 | Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> | |
1091 | ||
1092 | * devices.c (halt_io_write_buffer_callback): Use value written to | |
1093 | halt device to determine exit status. Thus allowing | |
1094 | success/failure of OEA tests. | |
1095 | ||
1096 | Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au> | |
1097 | ||
1098 | * ppc-instructions (icbi): If icache present flush it. | |
1099 | ||
1100 | Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au> | |
1101 | ||
1102 | * devices.c (htab_init_callback): Add code to create htab/pte. | |
1103 | ||
1104 | * devices.c (dma_file, file_init_callback, htab_init_callback): | |
1105 | New function - Dma the named file into memory at the specified | |
1106 | address. Use. | |
1107 | ||
1108 | * device_tree.h, device_tree.c (scand_*): New functions. | |
1109 | ||
1110 | Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au> | |
1111 | ||
1112 | * filter_filename.c, Makefile.in: Change so that only dependant on | |
1113 | a very limited nr of files. Stops an unnecessary dependency. | |
1114 | ||
1115 | Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au> | |
1116 | ||
1117 | * core.c (core_map_find_mapping): Use cpu_halt rather than error | |
1118 | to abort an access to an undefined address. | |
1119 | ||

1134 | WITH_PPC_{,DEFAULT_}_MODEL. | |
1135 | (options_ppc): Delete now unused function. | |
1136 | (cpu.h): Include cpu.h, not just basics.h. | |
1137 | ||

1153 | ||
1154 | * ppc-instructions: Add macros for flag defines. Switch first | |
1155 | model so 604 is first. | |

1176 | ||
1177 | * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS | |
1178 | instead of INLINE_SEMANTICS so that the compiler won't keep all of | |
1179 | the semantic functions as inline RTL, given that the address of | |
1180 | the function is taken which forces outline calls anyway. | |
1181 | (lf_print_c_semantic_function_header): Ditto. | |
1182 | (gen_semantics_h): Define STATIC_SEMANTICS as nothing if not | |
1183 | defined. | |
1184 | (lf_print_c_cracker_function): Emit STATIC_IDECODE instead of | |
1185 | STATIC_INLINE_IDECODE. | |
1186 | (gen_idecode_c): Define STATIC_IDECODE if not defined. | |

1573 | Make IO go through these functions. Add -b (bit size) and -h (high | |
1574 | bit nr) options to igen. Typical usage would be: ./igen -b 16 -h | |
1575 | 15 for a 16 bit instruction format with the msb given a number 15. | |

1582 | |
1583 | * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h, | |
1584 | debug.c: Add tracing of load/store unit (virtual) with -t | |
1585 | load-store. | |

1588 | |
1589 | * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does | |
1590 | not include things such as the time base and events. | |
1591 | ||
1592 | * interrupt.c, sim_calls.c, cpu.h, vm.c, configure.in: Add UEA to | |
1593 | all environment switches for above. | |
1594 | ||
1595 | * psim.c (psim_create): ditto - new device tree node name is | |
1596 | /options/environment-architecture with values user, virtual and | |

1600 | |
1601 | * ppc-opcode-stupid: Third example of use of opcode table - this | |
1602 | one expands all mtspr/mfspr and branch instructions. Appears to | |
1603 | give about a 10% gain in performance if everything enabled. Also | |
1604 | takes about 150mb of swap to build. | |

1607 | ||
1608 | * emul_netbsd.c (do_exit): Print arguments and close parenthesis | |
1609 | if tracing, since exit doesn't go through emul_exit_call. | |
1610 | (do_read): Print arguments if tracing. | |
1611 | (do_write): Ditto. | |
1612 | (do_open): Ditto. | |

1627 | the directory prefix from a file. | |
1628 | * filter_filename.h: New include file to declare filter_filename. | |
1629 | ||
1630 | * debug.h: Include filter_filename.h. | |
1631 | (TRACE,DTRACE,ERROR): Use filter_filename on __FILE__. | |
1632 | ||
1633 | * misc.h: Include filter_filename.h. | |
1634 | (ASSERT): Use filter_filename on __FILE__. | |
1635 | ||
1636 | * igen.c (lf_print_my_prefix): Use filter_filename on the filename | |
1637 | argument. | |
1638 | ||
1639 | * Makefile.in: Add filter_filename support. | |
1640 | ||
1641 | * ppc-instructions (dcbi, icbi): Make these NOPs rather than | |
1642 | invalid instructions. | |
1643 | ||
1644 | * configure.in: Add support for more --enable-sim-* switches. | |
1645 | Use config.make and config.hdr to write to Makefile and config.h | |
1646 | respectively. Don't rewrite Makefile, just append to it. | |
1647 | * configure: Regenerate. | |
1648 | * config.{make,hdr}: New shell scripts. | |
1649 | ||
1650 | * Makefile.in: Remove all variables set by configure.in. | |
1651 | (psim.o): Depend on $(BUILT_SRC) also. | |
1652 | ||
1653 | * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an | |
1654 | integer, use 0, not NULL. | |

1658 | * configure.in: Add support for --enable-sim-inline, | |
1659 | --enable-sim-bswap, --enable-sim-cflags, --enable-sim-complex, | |
1660 | --enable-sim-switch, --enable-sim-duplicate, --enable-sim-filter, | |
1661 | and --enable-sim-endian switch to control various Makefile | |
1662 | variables. | |
1663 | * configure: Regenerate from configure.in. | |
c143ef62 MM |
1664 | * Makefile.in: Add various Make variables that the various |
1665 | switches alter. | |
4b935ed4 MM |
1666 | |

1671 | |
1672 | * bits.h (ROTL32, ROTL64): Were functions, made them macros, now | |
1673 | make them functions again. Appears 2.6.3 is confused by just a | |
1674 | macro. | |

1677 | |
1678 | * ppc-endian.c (SWAP_8): Fix 8 byte swap! | |
1679 | ||
1680 | * psim.c (psim_create): Not correctly checking that runtime | |
1681 | configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT | |
1682 | matched the compiled in ones. | |
1683 | ||
1684 | * debug.h (ITRACE), igen.c: Tidy up more tracing flags - | |
1685 | trace_semantics is now different to trace_idecode, the former | |
1686 | checks the cache. | |
1687 | ||

5b4d72dd MM |
1700 | |
1701 | * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the | |
1702 | INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2. | |
1703 | Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE | |
1704 | DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on | |
1705 | the instruction or data critical paths. | |
1706 | ||
5b4d72dd MM |
1707 | * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from |
1708 | the inclusion of device_tree.c/emul_generic.c. | |
1709 | ||

5b4d72dd MM |
1711 | |
1712 | * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace | |
1713 | system.[hc]. Start of suport for multiple emulations and | |
1714 | emulation state (os_emul object). | |
1715 | ||
1716 | * emul_generic.[hc]: Start of code to implement proper system call | |
1717 | tracing (from spy). | |

5b4d72dd MM |
1720 | |
1721 | * cpu.h, cpu.c (cpu_init): New function, zero the registers before | |
1722 | the processor is started. Fixes problem of registers being | |
1723 | undefined when restarting from within gdb. | |
1724 | ||
1725 | * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the | |
1726 | instruction cache (if present). Fixes problem of cpu caching gdb | |
1727 | breakpoint instructions. | |
1728 | ||
1729 | FIXME: PSIM sometimes aborts calling error(), it should instead | |
1730 | call sim_error() say which takes care of housekeeping such as | |
1731 | saving the CIA before calling error. | |
1732 | ||
1733 | * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is | |
1734 | used when restarting a simulation because the latter has the | |
1735 | unwanted side effect (well I as a kernel hacker think it is) of | |
1736 | performing an isync when the instruction stream doesn't contain | |
1737 | one. | |

5b4d72dd MM |
1740 | |
1741 | * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance | |
1742 | monitoring module. Counts both instructions issued and | |
1743 | load/stores. | |
1744 | ||
1745 | * NOTE: mon does not contain to count instruction loads as this | |
1746 | information is already available from the mon_issue() hook. | |
1747 | ||
5b4d72dd MM |
1748 | * igen.c (lf_print_c_semantic), vm_n.h: Add counting code. |
1749 | ||
1750 | * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach | |
1751 | a common monitor to each of the cpus. Delete | |
1752 | cpu_increment_number_of_insns() and cpu_get_number_of_insns() | |
1753 | replaced by copied code in mon.[hc]. | |

5b4d72dd MM |
1756 | |
1757 | * sim_calls.c, main.c, psim.c (psim_create): always create | |
1758 | `WITH_SMP' cpus. The actual number of CPU's active in a | |
1759 | simulation run is taken from the device node: /init/smp (an | |
1760 | integer). WITH_SMP changed to 2 (remember to put it back to 0). | |

5b4d72dd MM |
1763 | |
1764 | * system.c: More system call emulation. If code appears NetBSD | |
1765 | specific, make conditional to being compiled on a NetBSD system | |
1766 | (sigh). | |
1767 | ||

1769 | |
1770 | * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new), | |
1771 | lf.[ch](new), table.[ch](new): Split into two generators - igen | |
1772 | that outputs the instruction tables and dgen that outputs the spr | |
1773 | tables. Add -f (filter out) flag to igen to filter out certain | |
1774 | instructions (ex 64 bit ones) from the created tables. Include | |
1775 | $(LIBIBERTY_LIB) in link options in case host lacks some libc | |
1776 | functions. | |
1777 | ||
1778 | * NOTE: igen, since it was originally written for the | |
1779 | PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}. | |
1780 | ||
1781 | * Makefile.in, std-config.h, ppc-cache-rules(new), | |
1782 | ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create | |
1783 | cache-rule and opcode-rule tables from macros found std-config.h. | |
1784 | Delete corresponding macro's from std-config.h. | |
1785 | ||
5b4d72dd MM |
1786 | * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output |
1787 | an table of all the instructions. Code to output a type | |
1788 | enumerating all the instructin names. | |
1789 | ||
1790 | * igen.c(lf_print_c_semantic): Move call to increment instruction | |
1791 | counter so that it occures _after_ the instruction has been fully | |
1792 | validated, was double counting illegal/invalid instructions. Add | |
1793 | conditional so only compiled in when WITH_PROFILE enabled (enabled | |
1794 | by default). | |
1795 | ||
1796 | * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include | |
1797 | itable.h, count individual instruction types not just total, | |
1798 | adjust reporting functions to output this. | |
1799 | ||
1800 | * ppc-instructions (64 bit Load Doubleword with Update Indexed): | |
1801 | Had 32./ instead of 31./ | |
1802 | ||
1803 | * ppc-instructions (64 bit Store Double Word Conditional Indexed): | |
1804 | bitrot - updated to use newer CR register operators. | |
1805 | ||
1806 | * ppc-instructions (64bit Floating Convert from Integer | |
1807 | Doubleword): Correct call to Round_Float(). | |

1811 | * basics.h: #include "sim_callbacks.h" earlier so that its | |
1812 | prototypes are declared in all other header files. | |
1813 | ||
1814 | * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update | |
1815 | doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into | |
1816 | bits.h. | |
1817 | ||
5b4d72dd MM |
1818 | * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*): |
1819 | Add size of buffer argument to functions writing a string into a | |
1820 | buffer. Check for buffer overflow. | |
1821 | ||

5b4d72dd MM |
1823 | |
1824 | * devices.h, devices.c, debug.h, debug.c: add macro's for tracing | |
1825 | of each device. Make parameter names consistent so macros work. | |
1826 | Use macro's in device functions. | |
1827 | ||
1828 | * device_tree.c, devices.h, devices.c: include path to device in a | |
1829 | devices node when creating it. | |

5b4d72dd MM |
1837 | |
1838 | * debug.h, debug.c (trace_option): New function. Parses the trace | |
1839 | option, updating the trace array. | |
1840 | ||
1841 | * debug.h, debug.c (trace_usage): New function. Outputs the list | |
1842 | of all possible trace options. | |
1843 | ||
1844 | * sim_calls.c (sim_open), main.c (main): Use new trace_option() to | |
1845 | parse trace options specified with the simpler -t flag. Adjust | |
1846 | usage. | |
1847 | ||
1848 | * FIXME: basic parsing of command line options is still duplicated | |
1849 | by main.c and sim_calls.c | |

1854 | ||
22ddef46 MM |
1855 | * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP |
1856 | macros for either assignment or return. Fix SWAP_8 to use a | |
1857 | union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now. | |
1858 | (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs | |
1859 | that hardwired swapping on/off, let optimizer delete dead code. | |
1860 | ||

1881 | * gen.c, ppc-instructions, psim.c: Fix code for generating | |
1882 | cracking instruction cache. Delete the code that cached just the | |
1883 | result from doing an instruction lookup - this ran slower than no | |
1884 | cache at all. | |

1907 | * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for |
1908 | 2, 4, and 8 bytes. | |
1909 | (ENDIAN_N): If both target and host byte orders are known, don't | |
1910 | bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER. | |
1911 | ||
1912 | * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0 | |
1913 | to allow target specific H2T_n/T2H_n macros to be used. | |
1914 | (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is | |
1915 | non-zero, redefine the htonl/ntohl macros to use the BSWAP instead | |
1916 | of the 3 instruction sequence that runs on 386s. | |
1917 | ||
1918 | * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if | |
1919 | specified on the compile line. | |
1920 | (WITH_BSWAP): If not defined, define as 0. | |
1921 | ||
8e20a3ac MM |
1922 | * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add |
1923 | default inline support. Pass INLINE_CFLAGS when compiling. | |
1924 | ||
1925 | * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not | |
1926 | INLINE_DEVICES since GCC doesn't like inline functions that | |
1927 | accept variable arguments. | |

1933 | * inline.c: Correct pathnames of included C files to match current | |
1934 | implementation. | |
1935 | ||
1936 | * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be | |
1937 | non-zero, define STATIC_DEVICES to be static. | |
1938 | ||
1939 | * std-config.h (INLINE): If GNU C and optimizing, define this as | |

1947 | |
1948 | * ppc-instructions: Initial cut of floating point suport added. | |
1949 | Of note include - use of host IEEE floating point instructions, | |
1950 | use of PowerPC manual pseudo code to handle the FPSCR. It is not | |
1951 | currently a pretty sight. | |
1952 | ||
1953 | * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c: | |
1954 | merge into core.h, core.c, core_n.h. The type memory_map replaced | |
1955 | with core_map. This removes a level of pointer indirection when | |
1956 | translating an address. | |
1957 | ||
1958 | * memory_map.h, memory_map.c, memory_map_n.h: delete. | |
1959 | ||
1960 | * Makefile.in et.al (sorry): tweek to use new core, core_map and | |
1961 | core.h. | |
1962 | ||

1964 | |
1965 | * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to | |
1966 | most of the other functions in sim_calls.c. | |
1967 | ||
1968 | * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in: | |
1969 | Add macros to better cover up `generic' code. Makes it possible | |
1970 | to step through the generic code! | |
1971 | ||
1972 | * vm.c, vm_n.h, Makefile.in: ditto | |
1973 | ||

8e20a3ac MM |
1975 | |
1976 | * devices.h, devices.c, memory_map.h, memory_map.c: Changed | |
1977 | callback interface so that there is a read/write buffer but no | |
1978 | read/write_word. VEA default memory read/write handler sometimes | |
1979 | couldn't resolve an access and of those some were for a memory | |
1980 | fault and some were because gdb was making a bogus request. | |
1981 | ||
1982 | * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c: | |
1983 | eliminate transfer_mode (raw or cooked) parameter from read/write | |
1984 | buffer. | |
1985 | ||

1992 | |
1993 | * psim.c, device_tree.h, device_tree.c, devices.c (printd_*, | |
1994 | scand_*): new functions to parse/print fields in device names | |
1995 | while hiding any machine dependency. | |
1996 | ||
1997 | * devices.c, psim.c: Change the stack init code so that it is | |
1998 | handled by a device. Arguments passed across using a device ioctl | |
1999 | (hack). | |
2000 | ||
2001 | * devices.h, devices.c: device ioctl callback changed to allow a | |
2002 | variable number of arguments. This gives greater flexability and | |
2003 | greater chance of bugs. | |
2004 | ||

2007 | * main.c (printf_filtered, error): Missing va_end() to close off | |
2008 | variable argument use. | |
2009 | ||
2010 | * Makefile.in (tmp-gencode): comment out hack to get around some | |
2011 | versions of make not handling files being created as side-effects. | |
2012 | ||
2013 | * gen.c (lf_open): Add -n (real_file_name) option. Specifies an | |
2014 | alternative file name to use in output files for things like #line | |
2015 | macros. | |
2016 | ||
2017 | Makefile.in (tmp-gencode): Use gen -n so that debug info is | |
2018 | correct. | |
2019 | ||
2020 | * Makefile.in (TARGETLIB): Use this instead of libsim.a in the | |
2021 | Makefile. | |

2217 | everything lives in the one directory. While a pain for cleaning, | |
2218 | makes building across multiple architectures much simpler. | |
2219 | ||
2220 | * devices.c, device_tree.c: Added code that provides a simple | |
2221 | illustration of how an interrupt control device could be | |
2222 | implemented. | |
