| 316 | * device_table.c (register_init): Extend properties attached to |
| 317 | register init node to allow a specific processor's register to be |
| 318 | specified. |
| 319 | |
| 320 | * emul_chirp.c (emul_chirp_create): Init SMP correctly - the |
| 321 | initial PC for all processors is an infinate loop but then, for |
| 322 | processor zero, is quickly changed to be the correct code starting |

| 324 | |
| 325 | * emul_chirp.c (emul_chirp_create): Add fake bootpath |
| 326 | et.al. properties to tree. |

| 352 | |
| 353 | FIXME: As mentioned earlier, the device stuff needs work to bring |

| 360 | better tracing. |
| 361 | |
| 362 | * emul_chrp.c: Change return type of emul functions to int. Emul |
| 363 | functions either return -1 or zero so unsigned was a bit |
| 364 | dangerous. |
| 365 | |
| 366 | * inline.h (*), igen.c, dgen.c, *: Update INLINE macros so that |
| 367 | they are paramaterised with the type of the function. Gets around |
| 368 | the problem of `static' needing to come first with `attribute' |
| 369 | comming last. Format declarations and definitions so that emacs |
| 370 | doesn't get confused. |
| 371 | |
| 372 | Fri Dec 15 17:06:44 1995 Andrew Cagney <cagney@highland.com.au> |
| 373 | |

| 378 | the number seconds used. |
| 379 | |
| 380 | * psim.c (run_until_stop): Don't monitor the cache misses when |
| 381 | monitoring is disabled. |
| 382 | |
| 383 | * configure.in (sim_mon, sim_monitor): Correct typo - sim_mon -> |
| 384 | sim_monitor for shell variable (or should that have been the other |
| 385 | way around?). |
| 386 | |
| 387 | * vm.c (vm_synchronize_context): Fix wrong test for unsuported |
| 388 | change in endian-mode. |
| 389 | |
| 390 | * std-config.h (WITH_REGPARM), inline.h (IDECODE_INLINE, |
| 391 | SEMANTICS_INLINE): Add -DWITH_REGPARM=<n> option. Enables the |
| 392 | __attribute__((__regparm(WITH_REGPARM))) for some functions. |
| 393 | configure with --enable-sim-cflags="-DWITH_REGPARAM=3" (say). |
| 394 | Unfortunatly it tickles a bug (gcc?) and can't be used. |
| 395 | |
| 396 | Mon Dec 18 13:36:06 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 397 | |

| 406 | |
| 407 | * emul_netbsd.c (emul_netbsd_create): Deal with new BFD that |

| 470 | |
| 471 | * sim_calls.c (sim_create, sim_load), main.c (main), psim.c: Pass |

| 473 | into the tree. |
| 474 | |
| 475 | * device.c (*add*): Change semantics so the add functions only add |
| 476 | when the new device (or property) doesn't already exist. This |
| 477 | allows merging of options and data. |
| 478 | |

| 499 | basic include files does not call functions delcared in later |
| 500 | #includes. |
| 501 | |
| 502 | * basics.h (__attribute__), sim_callbacks.h: Move attribute macro |
| 503 | to basics.h and add hack (include <stdio.h>) to try and bring that |
| 504 | and other possible conflicting macros into scope much earler. |
| 505 | |
| 506 | * sim-endian.h,c (SIM_ENDIAN_INLINE) bits.h,c (BITS_INLINE): |

| 527 | |
| 528 | * sim-endian.h (SWAP_N), sim-endian-n.h, sim-endian.c: How |
| 529 | embarasing - fix yet another bug in the swap code! Simplify |

| 605 | and code for spa, no longer to be used. |
| 606 | |
| 607 | * psim.c (create_chirp_device_tree): Fill out what was previously |

| 632 | |
| 633 | * configure{,.in} (--enable-sim-model-issue): Instead of defining |

| 677 | |
| 678 | * std-config.h (MODEL_INLINE): If not defined, define as 1 if |

| 843 | code successful/unsuccessful branch predictions, and the number of |
| 844 | conditional branches that fell through. |
| 845 | |
| 846 | Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com> |

| 871 | |
| 872 | Tue Nov 14 04:47:25 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 873 | |
| 874 | * Makefile.in (devices.o, main.o): Update dependency. |
| 875 | |
| 876 | * igen.c (gen_model_h): Use correct variable in loop. |
| 877 | (gen_model_c): Use strcmp, strcasecmp. |

| 885 | |
| 886 | Mon Nov 13 09:14:13 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 887 | |
| 888 | * igen.c ({insn,model}_table_fields): Spell mnemonic correctly. |
| 889 | (gen_itable_h,itable_c_insn): Ditto. |
| 890 | (model support): Move model support around, add support for |
| 891 | model-data, model-internal. Use annex field for model-macros |
| 892 | now. |
| 893 | |
| 894 | * configure.in (--enable-sim-inline): If --enable-sim-inline=no, |
| 895 | also define INLINE as nothing. |
| 896 | * configure: Regenerate. |
| 897 | |
| 898 | * std-config.h (INLINE): Rather than nuking INLINE, only define it |
| 899 | as __inline__ if any of the INLINE flags are non-zero. |
| 900 | |
| 901 | * options.c (print_options): Print out WITH_XOR_ENDAIN. |
| 902 | |
| 903 | Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au> |
| 904 | |
| 905 | * ppc-instructions (rfi): Add missing code. |
| 906 | |
| 907 | * cpu.c (cpu_get_time_base): Fix calculation of current value of |
| 908 | time base register. |
| 909 | |
| 910 | * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing |
| 911 | m[tf]tb with m[tf]spr. |
| 912 | |
| 913 | * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing |
| 914 | lower word. |
| 915 | |
| 916 | Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au> |
| 917 | |
| 918 | * std-config.h (INLINE, STATIC_INLINE): Was being set to static |
| 919 | inline.. Only problem being that with ppc-opcode-simple this gave |
| 920 | it the chance to inline all the idecode functions with potentially |
| 921 | disasterous results on a 16mb PC. For moment hobble INLINE. |
| 922 | |
| 923 | * configure.in, std-config.h (WITH_SMP): Make that 5 processors by |
| 924 | default ... |
| 925 | |
| 926 | * configure.in: Tweek flags passed to gcc for --with-sim-warnings. |
| 927 | Firstly make them errors and secondly remove the options gcc-245 |
| 928 | doesn't reconize. |
| 929 | |
| 930 | Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au> |
| 931 | |
| 932 | * misc.c (zalloc), cpu.c (cpu_init), devices |
| 933 | (console_io_read_buffer_callback, icu_io_read_buffer_callback, |
| 934 | vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset), |
| 935 | sim_calls.c (zalloc) : replace bzero() with memset(). |
| 936 | |
| 937 | * emul_netbsd.c (write_direntries), psim.c (psim_read_register, |
| 938 | psim_write_register): replace bcopy() with memcpy(). |
| 939 | |
| 940 | Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> |
| 941 | |
| 942 | * configure.in: for --disable-sim-inline (--enable-sim-inline=no), |
| 943 | force DEFAULT_INLINE to 0 rather then trusting the std |
| 944 | configuration. |
| 945 | |
| 946 | Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> |
| 947 | |
| 948 | * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix |
| 949 | generation of switch entries in tables - treat the same as |
| 950 | cracking/semantic functions. |
| 951 | |
| 952 | * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation |
| 953 | of a boolean switch statement (field zero or non-zero). |
| 954 | |
| 955 | * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the |
| 956 | switch/table generation ability of igen. |
| 957 | |
| 958 | * igen.c (idecode_switch_leaf): Fix code output when a switch |
| 959 | statement needs to look up a table. |
| 960 | |
| 961 | * igen.c (idecode_declare_if_switch): New function called from |
| 962 | gen_idecode_c - need to declare any idecode switch functions |
| 963 | before they are used in idecode tables. |
| 964 | |
| 965 | * igen.c (lf_print_c_cracker_function, idecode_crack_leaf, |
| 966 | idecode_crack_insn): Add is_inline_function argument to code |
| 967 | printing cracker functions which indicates if STATIC_IDECODE or |
| 968 | STATIC_INLINE_IDECODE should be used for definition. For |
| 969 | idecode_crack_insn (which implies not duplicating/expanding) don't |
| 970 | declare function as inline - we assume that the only time this is |
| 971 | code is generated is when things are being tested. For |
| 972 | idecode_crack_leaf, make static (instead of INLINE) if the |
| 973 | instructions parent is a table as function will always be called |
| 974 | via a table. |
| 975 | |
| 976 | * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not |
| 977 | STATIC_INLINE_IDECODE. Only the outermost idecode switch will be |
| 978 | called directly, all others are called via a table. |
| 979 | |
| 980 | * igen.c (lf_print_semantic_function_header, semantics_h_leaf, |
| 981 | semantics_h_insn, semantics_h_function, |
| 982 | lf_print_c_semantic_function, semantics_c_function): Add |
| 983 | is_inline_function argument to lf_print_semantic_function_header |
| 984 | to indicate if an inline or static function declaration/definition |
| 985 | should be output. Depending on situtation call accordingly: |
| 986 | functions (not instruction semantic routines) are always inline; |
| 987 | Semantic routines are made inline when there is no icache (cache |
| 988 | will contain the function address) and are duplicating (see above) |
| 989 | and the parent of the instruction is a switch statement. |
| 990 | |
| 991 | * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC |
| 992 | and moved to insn_table_find_opcode_field. |
| 993 | |
| 994 | * table.c (table_open): Fix typo (nr_model_fields vs nr_fields). |
| 995 | |
| 996 | * igen.c (model_c_insn): Suggestion - document the name of the |
| 997 | instruction on each line of the instruction model table. |
| 998 | |
| 999 | Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au> |
| 1000 | |
| 1001 | * emul_netbsd.c (do_ioctl): Cleanup compilation. |
| 1002 | |
| 1003 | * sim_callbacks.h (__attribute__): Only define if not defined (was |
| 1004 | already defined on NetBSD host). |
| 1005 | |
| 1006 | Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> |
| 1007 | |
| 1008 | * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New |
| 1009 | macro, indicates if the PowerPC's horrible XOR endian mode should |
| 1010 | be suported. Add to configure and make. |
| 1011 | |
| 1012 | * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c |
| 1013 | (vm_instruction_map_read): If XOR endian, xor the address |
| 1014 | with a value from an xor table (indexed by size of access). |
| 1015 | |
| 1016 | * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context): |
| 1017 | set up xor table to xor if there is a conflict between the |
| 1018 | CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move |
| 1019 | check of suported change of endian mode from cpu.c to vm.c. |
| 1020 | |
| 1021 | * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer): |
| 1022 | Hopefully added correct hack to handle XOR endian mode. |
| 1023 | |
| 1024 | FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates |
| 1025 | little endian mode, the model accepts miss aligned transfers. |
| 1026 | |
| 1027 | FIXME: Need to create an `init' device that, during |
| 1028 | initializatioin for XOR mode, it mushes (XOR address) all the dma |
| 1029 | data before passing it on to the core for storage. Just like the |
| 1030 | real thing really. |
| 1031 | |
| 1032 | Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> |
| 1033 | |
| 1034 | * devices.c (halt_io_write_buffer_callback): Use value written to |
| 1035 | halt device to determine exit status. Thus allowing |
| 1036 | success/failure of OEA tests. |
| 1037 | |
| 1038 | Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au> |
| 1039 | |
| 1040 | * ppc-instructions (icbi): If icache present flush it. |
| 1041 | |
| 1042 | Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au> |
| 1043 | |
| 1044 | * devices.c (htab_init_callback): Add code to create htab/pte. |
| 1045 | |
| 1046 | * devices.c (dma_file, file_init_callback, htab_init_callback): |
| 1047 | New function - Dma the named file into memory at the specified |
| 1048 | address. Use. |
| 1049 | |
| 1050 | * device_tree.h, device_tree.c (scand_*): New functions. |
| 1051 | |
| 1052 | Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au> |
| 1053 | |
| 1054 | * filter_filename.c, Makefile.in: Change so that only dependant on |
| 1055 | a very limited nr of files. Stops an unnecessary dependency. |
| 1056 | |
| 1057 | Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au> |
| 1058 | |
| 1059 | * core.c (core_map_find_mapping): Use cpu_halt rather than error |
| 1060 | to abort an access to an undefined address. |
| 1061 | |
| 1062 | Sun Nov 12 07:58:09 1995 Michael Meissner <meissner@tiktok.cygnus.com> |

| 1120 | instead of INLINE_SEMANTICS so that the compiler won't keep all of |
| 1121 | the semantic functions as inline RTL, given that the address of |
| 1122 | the function is taken which forces outline calls anyway. |
| 1123 | (lf_print_c_semantic_function_header): Ditto. |
| 1124 | (gen_semantics_h): Define STATIC_SEMANTICS as nothing if not |
| 1125 | defined. |

| 1165 | functional units of a particular machine model. |

| 1170 | |

| 1612 | Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au> |
| 1613 | |
| 1614 | * bits.h (ROTL32, ROTL64): Were functions, made them macros, now |
| 1615 | make them functions again. Appears 2.6.3 is confused by just a |
| 1616 | macro. |
| 1617 | |
| 1618 | Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au> |
| 1619 | |
| 1620 | * ppc-endian.c (SWAP_8): Fix 8 byte swap! |
| 1621 | |
| 1622 | * psim.c (psim_create): Not correctly checking that runtime |
| 1623 | configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT |
| 1624 | matched the compiled in ones. |
| 1625 | |
| 1626 | * debug.h (ITRACE), igen.c: Tidy up more tracing flags - |
| 1627 | trace_semantics is now different to trace_idecode, the former |
| 1628 | checks the cache. |
| 1629 | |
| 1630 | Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au> |
| 1631 | |
| 1632 | * ppc-instructions (mtsrin): Missing instruction |
| 1633 | * ppc-instructions (mfsrin): Missing instruction |
| 1634 | * ppc-instructions (eieio): Missing instruction |
| 1635 | |
| 1636 | Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au> |
| 1637 | |
| 1638 | * build-psim: New shell script - see internals for usage, |
| 1639 | simplifies the process of building custom simulators. |
| 1640 | |
| 1641 | Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au> |
| 1642 | |
| 1643 | * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the |
| 1644 | INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2. |
| 1645 | Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE |
| 1646 | DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on |
| 1647 | the instruction or data critical paths. |
| 1648 | |
| 1649 | * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from |
| 1650 | the inclusion of device_tree.c/emul_generic.c. |
| 1651 | |
| 1652 | Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au> |
| 1653 | |
| 1654 | * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace |
| 1655 | system.[hc]. Start of suport for multiple emulations and |
| 1656 | emulation state (os_emul object). |
| 1657 | |
| 1658 | * emul_generic.[hc]: Start of code to implement proper system call |
| 1659 | tracing (from spy). |
| 1660 | |
| 1661 | Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au> |
| 1662 | |
| 1663 | * cpu.h, cpu.c (cpu_init): New function, zero the registers before |
| 1664 | the processor is started. Fixes problem of registers being |
| 1665 | undefined when restarting from within gdb. |
| 1666 | |
| 1667 | * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the |
| 1668 | instruction cache (if present). Fixes problem of cpu caching gdb |
| 1669 | breakpoint instructions. |
| 1670 | |
| 1671 | FIXME: PSIM sometimes aborts calling error(), it should instead |
| 1672 | call sim_error() say which takes care of housekeeping such as |
| 1673 | saving the CIA before calling error. |
| 1674 | |
| 1675 | * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is |
| 1676 | used when restarting a simulation because the latter has the |
| 1677 | unwanted side effect (well I as a kernel hacker think it is) of |
| 1678 | performing an isync when the instruction stream doesn't contain |
| 1679 | one. |
| 1680 | |
| 1681 | Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au> |
| 1682 | |
| 1683 | * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance |
| 1684 | monitoring module. Counts both instructions issued and |
| 1685 | load/stores. |
| 1686 | |
| 1687 | * NOTE: mon does not contain to count instruction loads as this |
| 1688 | information is already available from the mon_issue() hook. |
| 1689 | |
| 1690 | * igen.c (lf_print_c_semantic), vm_n.h: Add counting code. |
| 1691 | |
| 1692 | * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach |
| 1693 | a common monitor to each of the cpus. Delete |
| 1694 | cpu_increment_number_of_insns() and cpu_get_number_of_insns() |
| 1695 | replaced by copied code in mon.[hc]. |
| 1696 | |
| 1697 | Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au> |
| 1698 | |
| 1699 | * sim_calls.c, main.c, psim.c (psim_create): always create |
| 1700 | `WITH_SMP' cpus. The actual number of CPU's active in a |
| 1701 | simulation run is taken from the device node: /init/smp (an |
| 1702 | integer). WITH_SMP changed to 2 (remember to put it back to 0). |
| 1703 | |
| 1704 | Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au> |
| 1705 | |
| 1706 | * system.c: More system call emulation. If code appears NetBSD |
| 1707 | specific, make conditional to being compiled on a NetBSD system |
| 1708 | (sigh). |
| 1709 | |
| 1710 | Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au> |
| 1711 | |
| 1712 | * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new), |
| 1713 | lf.[ch](new), table.[ch](new): Split into two generators - igen |
| 1714 | that outputs the instruction tables and dgen that outputs the spr |
| 1715 | tables. Add -f (filter out) flag to igen to filter out certain |
| 1716 | instructions (ex 64 bit ones) from the created tables. Include |
| 1717 | $(LIBIBERTY_LIB) in link options in case host lacks some libc |
| 1718 | functions. |
| 1719 | |
| 1720 | * NOTE: igen, since it was originally written for the |
| 1721 | PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}. |
| 1722 | |
| 1723 | * Makefile.in, std-config.h, ppc-cache-rules(new), |
| 1724 | ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create |
| 1725 | cache-rule and opcode-rule tables from macros found std-config.h. |
| 1726 | Delete corresponding macro's from std-config.h. |
| 1727 | |
| 1728 | * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output |
| 1729 | an table of all the instructions. Code to output a type |
| 1730 | enumerating all the instructin names. |
| 1731 | |
| 1732 | * igen.c(lf_print_c_semantic): Move call to increment instruction |
| 1733 | counter so that it occures _after_ the instruction has been fully |
| 1734 | validated, was double counting illegal/invalid instructions. Add |
| 1735 | conditional so only compiled in when WITH_PROFILE enabled (enabled |
| 1736 | by default). |
| 1737 | |
| 1738 | * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include |
| 1739 | itable.h, count individual instruction types not just total, |
| 1740 | adjust reporting functions to output this. |
| 1741 | |
| 1742 | * ppc-instructions (64 bit Load Doubleword with Update Indexed): |
| 1743 | Had 32./ instead of 31./ |
| 1744 | |
| 1745 | * ppc-instructions (64 bit Store Double Word Conditional Indexed): |
| 1746 | bitrot - updated to use newer CR register operators. |
| 1747 | |
| 1748 | * ppc-instructions (64bit Floating Convert from Integer |
| 1749 | Doubleword): Correct call to Round_Float(). |
| 1750 | |
| 1751 | Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au> |
| 1752 | |
| 1753 | * basics.h: #include "sim_callbacks.h" earlier so that its |
| 1754 | prototypes are declared in all other header files. |
| 1755 | |
| 1756 | * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update |
| 1757 | doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into |
| 1758 | bits.h. |
| 1759 | |
| 1760 | * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*): |
| 1761 | Add size of buffer argument to functions writing a string into a |
| 1762 | buffer. Check for buffer overflow. |
| 1763 | |
| 1764 | Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au> |
| 1765 | |
| 1766 | * devices.h, devices.c, debug.h, debug.c: add macro's for tracing |
| 1767 | of each device. Make parameter names consistent so macros work. |
| 1768 | Use macro's in device functions. |
| 1769 | |
| 1770 | * device_tree.c, devices.h, devices.c: include path to device in a |
| 1771 | devices node when creating it. |
| 1772 | |
| 1773 | * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'. |
| 1774 | |
| 1775 | * core.c: add tracing of core-device, adjust parameter names in |
| 1776 | core functions to be consistent with those in devices*. |
| 1777 | |
| 1778 | Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au> |
| 1779 | |
| 1780 | * debug.h, debug.c (trace_option): New function. Parses the trace |
| 1781 | option, updating the trace array. |
| 1782 | |
| 1783 | * debug.h, debug.c (trace_usage): New function. Outputs the list |
| 1784 | of all possible trace options. |
| 1785 | |
| 1786 | * sim_calls.c (sim_open), main.c (main): Use new trace_option() to |
| 1787 | parse trace options specified with the simpler -t flag. Adjust |
| 1788 | usage. |
| 1789 | |
| 1790 | * FIXME: basic parsing of command line options is still duplicated |
| 1791 | by main.c and sim_calls.c |
| 1792 | |
| 1793 | Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1794 | |
| 1795 | * Makefile.in (clean): Delete *.i and *.out files. |
| 1796 | |
| 1797 | * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP |
| 1798 | macros for either assignment or return. Fix SWAP_8 to use a |
| 1799 | union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now. |
| 1800 | (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs |
| 1801 | that hardwired swapping on/off, let optimizer delete dead code. |
| 1802 | |
| 1803 | * main.c (main): Add printf that we caught a signal and print out |
| 1804 | the failing address. |
| 1805 | |
| 1806 | Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com> |
| 1807 | |
| 1808 | * Makefile.in: Remove tabs from otherwise empty line. |
| 1809 | Confuses many non-GNU versions of "make". |
| 1810 | |
| 1811 | Wed Oct 18 08:51:25 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1812 | |
| 1813 | * Makefile.in (clean): Delete files produced by gen. |
| 1814 | |
| 1815 | Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1816 | |
| 1817 | * gen.c (lf_print_c_semantic_function): Move counting # of |
| 1818 | instructions here so it works with caching. |
| 1819 | (gen_idecode_c): Move from here. |
| 1820 | |
| 1821 | Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au> |
| 1822 | |
| 1823 | * gen.c, ppc-instructions, psim.c: Fix code for generating |
| 1824 | cracking instruction cache. Delete the code that cached just the |
| 1825 | result from doing an instruction lookup - this ran slower than no |
| 1826 | cache at all. |
| 1827 | |
| 1828 | Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1829 | |
| 1830 | * Makefile.in (gen.o): Include $(INLINE_CFLAGS). |
| 1831 | |
| 1832 | * debug.h (ppc_trace): Rename from trace, to avoid a conflict with |
| 1833 | TCL when gdb is linked with the simulator. |
| 1834 | * debug.c (ppc_trace): Ditto. |
| 1835 | * sim_calls.c (sim_open): Change trace -> ppc_trace. |
| 1836 | * main.c (main): Ditto. |
| 1837 | |
| 1838 | * cpu.c (cpu_add_commas): Remove extra static. |
| 1839 | |
| 1840 | Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1841 | |
| 1842 | * Makefile.in (psim.o): Now that inlines are turned on, make |
| 1843 | psim.o depend on all sources. |
| 1844 | |
| 1845 | * cpu.c (cpu_add_commas): New function to format a long with |
| 1846 | commas. |
| 1847 | (cpu_print_info): Use it to print number_of_insns. |
| 1848 | |
| 1849 | * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for |
| 1850 | 2, 4, and 8 bytes. |
| 1851 | (ENDIAN_N): If both target and host byte orders are known, don't |
| 1852 | bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER. |
| 1853 | |
| 1854 | * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0 |
| 1855 | to allow target specific H2T_n/T2H_n macros to be used. |
| 1856 | (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is |
| 1857 | non-zero, redefine the htonl/ntohl macros to use the BSWAP instead |
| 1858 | of the 3 instruction sequence that runs on 386s. |
| 1859 | |
| 1860 | * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if |
| 1861 | specified on the compile line. |
| 1862 | (WITH_BSWAP): If not defined, define as 0. |
| 1863 | |
| 1864 | * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add |
| 1865 | default inline support. Pass INLINE_CFLAGS when compiling. |
| 1866 | |
| 1867 | * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not |
| 1868 | INLINE_DEVICES since GCC doesn't like inline functions that |
| 1869 | accept variable arguments. |
| 1870 | (stack_ioctl_callback): Make function just static because GCC |
| 1871 | doesn't like inline functions that accept variable arguments. |
| 1872 | |
| 1873 | * devices.h (STATIC_DEVICES): Define as empty if not defined. |
| 1874 | |
| 1875 | * inline.c: Correct pathnames of included C files to match current |
| 1876 | implementation. |
| 1877 | |
| 1878 | * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be |
| 1879 | non-zero, define STATIC_DEVICES to be static. |
| 1880 | |
| 1881 | * std-config.h (INLINE): If GNU C and optimizing, define this as |
| 1882 | __inline__. |
| 1883 | (DEFAULT_INLINE): If not defined, define as 0. |
| 1884 | (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE. |
| 1885 | ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto. |
| 1886 | ({SPREG,IDECODE}_INLINE): Ditto. |
| 1887 | |
| 1888 | Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au> |
| 1889 | |
| 1890 | * ppc-instructions: Initial cut of floating point suport added. |
| 1891 | Of note include - use of host IEEE floating point instructions, |
| 1892 | use of PowerPC manual pseudo code to handle the FPSCR. It is not |
| 1893 | currently a pretty sight. |
| 1894 | |
| 1895 | * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c: |
| 1896 | merge into core.h, core.c, core_n.h. The type memory_map replaced |
| 1897 | with core_map. This removes a level of pointer indirection when |
| 1898 | translating an address. |
| 1899 | |
| 1900 | * memory_map.h, memory_map.c, memory_map_n.h: delete. |
| 1901 | |
| 1902 | * Makefile.in et.al (sorry): tweek to use new core, core_map and |
| 1903 | core.h. |
| 1904 | |
| 1905 | Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@highland.com.au> |
| 1906 | |
| 1907 | * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to |
| 1908 | most of the other functions in sim_calls.c. |
| 1909 | |
| 1910 | * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in: |
| 1911 | Add macros to better cover up `generic' code. Makes it possible |
| 1912 | to step through the generic code! |
| 1913 | |
| 1914 | * vm.c, vm_n.h, Makefile.in: ditto |
| 1915 | |
| 1916 | Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au> |
| 1917 | |
| 1918 | * devices.h, devices.c, memory_map.h, memory_map.c: Changed |
| 1919 | callback interface so that there is a read/write buffer but no |
| 1920 | read/write_word. VEA default memory read/write handler sometimes |
| 1921 | couldn't resolve an access and of those some were for a memory |
| 1922 | fault and some were because gdb was making a bogus request. |
| 1923 | |
| 1924 | * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c: |
| 1925 | eliminate transfer_mode (raw or cooked) parameter from read/write |
| 1926 | buffer. |
| 1927 | |
| 1928 | Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au> |
| 1929 | |
| 1930 | * ppc-instructions (fmul, fmuls): correct instruction format - had |
| 1931 | FRB instead of FRC. |
| 1932 | |
| 1933 | Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au> |
| 1934 | |
| 1935 | * psim.c, device_tree.h, device_tree.c, devices.c (printd_*, |
| 1936 | scand_*): new functions to parse/print fields in device names |
| 1937 | while hiding any machine dependency. |
| 1938 | |
| 1939 | * devices.c, psim.c: Change the stack init code so that it is |
| 1940 | handled by a device. Arguments passed across using a device ioctl |
| 1941 | (hack). |
| 1942 | |
| 1943 | * devices.h, devices.c: device ioctl callback changed to allow a |
| 1944 | variable number of arguments. This gives greater flexability and |
| 1945 | greater chance of bugs. |
| 1946 | |
| 1947 | Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au> |
| 1948 | |
| 1949 | * main.c (printf_filtered, error): Missing va_end() to close off |
| 1950 | variable argument use. |
| 1951 | |
| 1952 | * Makefile.in (tmp-gencode): comment out hack to get around some |
| 1953 | versions of make not handling files being created as side-effects. |
| 1954 | |
| 1955 | * gen.c (lf_open): Add -n (real_file_name) option. Specifies an |
| 1956 | alternative file name to use in output files for things like #line |
| 1957 | macros. |
| 1958 | |
| 1959 | Makefile.in (tmp-gencode): Use gen -n so that debug info is |
| 1960 | correct. |
| 1961 | |
| 1962 | * Makefile.in (TARGETLIB): Use this instead of libsim.a in the |
| 1963 | Makefile. |
| 1964 | |
| 1965 | Sat Oct 7 22:40:59 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1966 | |
| 1967 | * sim_calls.c (sim_set_callbacks): Define new function. |
| 1968 | |
| 1969 | Fri Oct 6 17:23:10 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1970 | |
| 1971 | * psim.c (psim_print_info): Print exit status or signal number. |
| 1972 | |
| 1973 | Mon Oct 2 11:46:37 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| 1974 | |
| 1975 | * cpu.c (struct _cpu): Add number_of_insns field to trace how many |
| 1976 | instructions are executed. |
| 1977 | (cpu_increment_number_of_insns): New function to increment the |
| 1978 | number of instructions issued. |
| 1979 | (cpu_get_number_of_insns): New function to return the number of |
| 1980 | instructions issued. |
| 1981 | (cpu_print_info): New function to print cpu related information. |
| 1982 | At present, print the number of instructions executed. |
| 1983 | |
| 1984 | * gen_idecode_c: Emit call to cpu_increment_number_of_insns within |
| 1985 | idecode_issue. |
| 1986 | |
| 1987 | * psim.c (psim_print_info): New function to iterate over each of |
| 1988 | the CPU's calling cpu_print_info. |
| 1989 | |
| 1990 | * psim.h,cpu.h: Add new declarations. |
| 1991 | |
