| change in endian-mode. |
| |
| * std-config.h (WITH_REGPARM), inline.h (IDECODE_INLINE, |

| Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au> |
| |
| * std-config.h (INLINE, STATIC_INLINE): Was being set to static |
| inline.. Only problem being that with ppc-opcode-simple this gave |
| it the chance to inline all the idecode functions with potentially |
| disasterous results on a 16mb PC. For moment hobble INLINE. |
| |
| * configure.in, std-config.h (WITH_SMP): Make that 5 processors by |
| default ... |
| |
| * configure.in: Tweek flags passed to gcc for --with-sim-warnings. |
| Firstly make them errors and secondly remove the options gcc-245 |
| doesn't reconize. |
| |
| Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * misc.c (zalloc), cpu.c (cpu_init), devices |
| (console_io_read_buffer_callback, icu_io_read_buffer_callback, |
| vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset), |
| sim_calls.c (zalloc) : replace bzero() with memset(). |
| |
| * emul_netbsd.c (write_direntries), psim.c (psim_read_register, |
| psim_write_register): replace bcopy() with memcpy(). |
| |
| Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> |
| |

| force DEFAULT_INLINE to 0 rather then trusting the std |
| configuration. |
| |
| Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> |
| |
| * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix |
| generation of switch entries in tables - treat the same as |
| cracking/semantic functions. |
| |
| * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation |
| of a boolean switch statement (field zero or non-zero). |
| |
| * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the |
| switch/table generation ability of igen. |
| |
| * igen.c (idecode_switch_leaf): Fix code output when a switch |
| statement needs to look up a table. |
| |
| * igen.c (idecode_declare_if_switch): New function called from |
| gen_idecode_c - need to declare any idecode switch functions |
| before they are used in idecode tables. |
| |
| * igen.c (lf_print_c_cracker_function, idecode_crack_leaf, |
| idecode_crack_insn): Add is_inline_function argument to code |
| printing cracker functions which indicates if STATIC_IDECODE or |
| STATIC_INLINE_IDECODE should be used for definition. For |
| idecode_crack_insn (which implies not duplicating/expanding) don't |
| declare function as inline - we assume that the only time this is |
| code is generated is when things are being tested. For |
| idecode_crack_leaf, make static (instead of INLINE) if the |
| instructions parent is a table as function will always be called |
| via a table. |
| |
| * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not |
| STATIC_INLINE_IDECODE. Only the outermost idecode switch will be |
| called directly, all others are called via a table. |
| |
| * igen.c (lf_print_semantic_function_header, semantics_h_leaf, |
| semantics_h_insn, semantics_h_function, |
| lf_print_c_semantic_function, semantics_c_function): Add |
| is_inline_function argument to lf_print_semantic_function_header |
| to indicate if an inline or static function declaration/definition |
| should be output. Depending on situtation call accordingly: |
| functions (not instruction semantic routines) are always inline; |
| Semantic routines are made inline when there is no icache (cache |
| will contain the function address) and are duplicating (see above) |
| and the parent of the instruction is a switch statement. |
| |
| * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC |
| and moved to insn_table_find_opcode_field. |
| |
| * table.c (table_open): Fix typo (nr_model_fields vs nr_fields). |
| |
| * igen.c (model_c_insn): Suggestion - document the name of the |
| instruction on each line of the instruction model table. |
| |

| * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New |
| macro, indicates if the PowerPC's horrible XOR endian mode should |
| be suported. Add to configure and make. |
| |
| * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c |
| (vm_instruction_map_read): If XOR endian, xor the address |
| with a value from an xor table (indexed by size of access). |
| |
| * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context): |
| set up xor table to xor if there is a conflict between the |
| CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move |
| check of suported change of endian mode from cpu.c to vm.c. |
| |
| * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer): |
| Hopefully added correct hack to handle XOR endian mode. |
| |
| FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates |
| little endian mode, the model accepts miss aligned transfers. |
| |
| FIXME: Need to create an `init' device that, during |
| initializatioin for XOR mode, it mushes (XOR address) all the dma |
| data before passing it on to the core for storage. Just like the |
| real thing really. |
| |
| Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> |
| |
| * devices.c (halt_io_write_buffer_callback): Use value written to |
| halt device to determine exit status. Thus allowing |
| success/failure of OEA tests. |

| |
| Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au> |
| |
| * filter_filename.c, Makefile.in: Change so that only dependant on |
| a very limited nr of files. Stops an unnecessary dependency. |

| |
| * core.c (core_map_find_mapping): Use cpu_halt rather than error |

| * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the |
| INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2. |
| Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE |
| DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on |
| the instruction or data critical paths. |
| |
| * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from |
| the inclusion of device_tree.c/emul_generic.c. |
| |
| Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace |
| system.[hc]. Start of suport for multiple emulations and |
| emulation state (os_emul object). |
| |
| * emul_generic.[hc]: Start of code to implement proper system call |
| tracing (from spy). |
| |
| Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * cpu.h, cpu.c (cpu_init): New function, zero the registers before |
| the processor is started. Fixes problem of registers being |
| undefined when restarting from within gdb. |
| |
| * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the |
| instruction cache (if present). Fixes problem of cpu caching gdb |
| breakpoint instructions. |
| |
| FIXME: PSIM sometimes aborts calling error(), it should instead |
| call sim_error() say which takes care of housekeeping such as |
| saving the CIA before calling error. |
| |
| * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is |
| used when restarting a simulation because the latter has the |
| unwanted side effect (well I as a kernel hacker think it is) of |
| performing an isync when the instruction stream doesn't contain |
| one. |
| |
| Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance |
| monitoring module. Counts both instructions issued and |
| load/stores. |
| |

| information is already available from the mon_issue() hook. |
| |
| * igen.c (lf_print_c_semantic), vm_n.h: Add counting code. |
| |
| * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach |
| a common monitor to each of the cpus. Delete |
| cpu_increment_number_of_insns() and cpu_get_number_of_insns() |
| replaced by copied code in mon.[hc]. |
| |
| Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * sim_calls.c, main.c, psim.c (psim_create): always create |
| `WITH_SMP' cpus. The actual number of CPU's active in a |
| simulation run is taken from the device node: /init/smp (an |
| integer). WITH_SMP changed to 2 (remember to put it back to 0). |
| |
| Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * system.c: More system call emulation. If code appears NetBSD |
| specific, make conditional to being compiled on a NetBSD system |
| (sigh). |
| |
| Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new), |
| lf.[ch](new), table.[ch](new): Split into two generators - igen |
| that outputs the instruction tables and dgen that outputs the spr |
| tables. Add -f (filter out) flag to igen to filter out certain |
| instructions (ex 64 bit ones) from the created tables. Include |
| $(LIBIBERTY_LIB) in link options in case host lacks some libc |
| functions. |
| |
| * NOTE: igen, since it was originally written for the |
| PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}. |
| |
| * Makefile.in, std-config.h, ppc-cache-rules(new), |
| ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create |
| cache-rule and opcode-rule tables from macros found std-config.h. |
| Delete corresponding macro's from std-config.h. |
| |
| * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output |
| an table of all the instructions. Code to output a type |
| enumerating all the instructin names. |
| |
| * igen.c(lf_print_c_semantic): Move call to increment instruction |
| counter so that it occures _after_ the instruction has been fully |
| validated, was double counting illegal/invalid instructions. Add |
| conditional so only compiled in when WITH_PROFILE enabled (enabled |
| by default). |
| |
| * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include |
| itable.h, count individual instruction types not just total, |
| adjust reporting functions to output this. |
| |
| * ppc-instructions (64 bit Load Doubleword with Update Indexed): |
| Had 32./ instead of 31./ |
| |
| * ppc-instructions (64 bit Store Double Word Conditional Indexed): |
| bitrot - updated to use newer CR register operators. |
| |
| * ppc-instructions (64bit Floating Convert from Integer |
| Doubleword): Correct call to Round_Float(). |
| |
| Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * basics.h: #include "sim_callbacks.h" earlier so that its |
| prototypes are declared in all other header files. |
| |
| * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update |
| doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into |
| bits.h. |
| |
| * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*): |
| Add size of buffer argument to functions writing a string into a |
| buffer. Check for buffer overflow. |
| |
| Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * devices.h, devices.c, debug.h, debug.c: add macro's for tracing |
| of each device. Make parameter names consistent so macros work. |
| Use macro's in device functions. |
| |
| * device_tree.c, devices.h, devices.c: include path to device in a |
| devices node when creating it. |
| |
| * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'. |
| |

| core functions to be consistent with those in devices*. |
| |
| Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au> |
| |

| option, updating the trace array. |
| |
| * debug.h, debug.c (trace_usage): New function. Outputs the list |
| of all possible trace options. |
| |
| * sim_calls.c (sim_open), main.c (main): Use new trace_option() to |
| parse trace options specified with the simpler -t flag. Adjust |
| usage. |
| |
| * FIXME: basic parsing of command line options is still duplicated |
| by main.c and sim_calls.c |
| |
| Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| |
| * Makefile.in (clean): Delete *.i and *.out files. |
| |
| * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP |
| macros for either assignment or return. Fix SWAP_8 to use a |
| union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now. |
| (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs |
| that hardwired swapping on/off, let optimizer delete dead code. |
| |
| * main.c (main): Add printf that we caught a signal and print out |
| the failing address. |
| |
| Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com> |
| |
| * Makefile.in: Remove tabs from otherwise empty line. |

| |
| * gen.c, ppc-instructions, psim.c: Fix code for generating |
| cracking instruction cache. Delete the code that cached just the |
| result from doing an instruction lookup - this ran slower than no |
| cache at all. |
| |
| Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com> |
| |
| * Makefile.in (gen.o): Include $(INLINE_CFLAGS). |

| commas. |
| (cpu_print_info): Use it to print number_of_insns. |
| |
| * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for |
| 2, 4, and 8 bytes. |
| (ENDIAN_N): If both target and host byte orders are known, don't |
| bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER. |
| |
| * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0 |
| to allow target specific H2T_n/T2H_n macros to be used. |
| (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is |
| non-zero, redefine the htonl/ntohl macros to use the BSWAP instead |
| of the 3 instruction sequence that runs on 386s. |
| |
| * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if |
| specified on the compile line. |
| (WITH_BSWAP): If not defined, define as 0. |
| |
| * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add |
| default inline support. Pass INLINE_CFLAGS when compiling. |
| |
| * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not |
| INLINE_DEVICES since GCC doesn't like inline functions that |
| accept variable arguments. |
| (stack_ioctl_callback): Make function just static because GCC |
| doesn't like inline functions that accept variable arguments. |
| |
| * devices.h (STATIC_DEVICES): Define as empty if not defined. |
| |
| * inline.c: Correct pathnames of included C files to match current |
| implementation. |
| |

| __inline__. |
| (DEFAULT_INLINE): If not defined, define as 0. |
| (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE. |
| ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto. |

| |
| Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * ppc-instructions: Initial cut of floating point suport added. |
| Of note include - use of host IEEE floating point instructions, |
| use of PowerPC manual pseudo code to handle the FPSCR. It is not |
| currently a pretty sight. |
| |
| * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c: |
| merge into core.h, core.c, core_n.h. The type memory_map replaced |
| with core_map. This removes a level of pointer indirection when |
| translating an address. |
| |
| * memory_map.h, memory_map.c, memory_map_n.h: delete. |
| |
| * Makefile.in et.al (sorry): tweek to use new core, core_map and |

| |
| Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * devices.h, devices.c, memory_map.h, memory_map.c: Changed |
| callback interface so that there is a read/write buffer but no |
| read/write_word. VEA default memory read/write handler sometimes |
| couldn't resolve an access and of those some were for a memory |
| fault and some were because gdb was making a bogus request. |
| |
| * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c: |
| eliminate transfer_mode (raw or cooked) parameter from read/write |
| buffer. |
| |
| Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * ppc-instructions (fmul, fmuls): correct instruction format - had |

| scand_*): new functions to parse/print fields in device names |
| while hiding any machine dependency. |
| |
| * devices.c, psim.c: Change the stack init code so that it is |
| handled by a device. Arguments passed across using a device ioctl |
| (hack). |
| |
| * devices.h, devices.c: device ioctl callback changed to allow a |
| variable number of arguments. This gives greater flexability and |
| greater chance of bugs. |
| |
| Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * main.c (printf_filtered, error): Missing va_end() to close off |
| variable argument use. |
| |
| * Makefile.in (tmp-gencode): comment out hack to get around some |
| versions of make not handling files being created as side-effects. |
| |
| * gen.c (lf_open): Add -n (real_file_name) option. Specifies an |
| alternative file name to use in output files for things like #line |
| macros. |
| |
| Makefile.in (tmp-gencode): Use gen -n so that debug info is |
| correct. |
| |
| * Makefile.in (TARGETLIB): Use this instead of libsim.a in the |
| Makefile. |

| At present, print the number of instructions executed. |
| |
| * gen_idecode_c: Emit call to cpu_increment_number_of_insns within |
| idecode_issue. |
| |

| |
| Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney@highland.com.au> |

| |
| Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au> |
| |
| * system.c (system_call): Fix SYS_break - was aligning bss to a |

| illustration of how an interrupt control device could be |
| implemented. |
| |
| * devices.c: Added code so that the dumb console device can read |
