   1 Fri Oct 27 19:26:27 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
   2
   3         * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
   4         make them functions again.  Appears 2.6.3 is confused by just a
   5         macro.
   6
   7 Thu Oct 26 18:31:58 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
   8
   9         * ppc-endian.c (SWAP_8): Fix 8 byte swap!
  10
  11         * psim.c (psim_create): Not correctly checking that runtime
  12         configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
  13         matched the compiled in ones.
  14
  15         * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
  16         trace_semantics is now different to trace_idecode, the former
  17         checks the cache.
  18
  19 Tue Oct 24 21:54:13 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
  20
  21         * ppc-instructions (mtsrin): Missing instruction
  22         * ppc-instructions (mfsrin): Missing instruction
  23         * ppc-instructions (eieio): Missing instruction
  24
  25 Tue Oct 24 20:55:29 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
  26
  27         * build-psim: New shell script - see internals for usage,
  28         simplifies the process of building custom simulators.
  29
  30 Mon Oct 23 23:48:59 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
  31
  32         * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
  33         INLINE macros.  Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
  34         Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
  35         DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
  36         the instruction or data critical paths.
  37
  38         * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
  39         not on critical path.
  40
  41         * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
  42         the inclusion of device_tree.c/emul_generic.c.
  43
  44 Mon Oct 23 00:31:50 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
  45
  46         * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
  47         system.[hc].  Start of suport for multiple emulations and
  48         emulation state (os_emul object).
  49
  50         * emul_generic.[hc]: Start of code to implement proper system call
  51         tracing (from spy).
  52
  53 Sun Oct 22 21:33:51 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
  54
  55         * cpu.h, cpu.c (cpu_init): New function, zero the registers before
  56         the processor is started. Fixes problem of registers being
  57         undefined when restarting from within gdb.
  58
  59         * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
  60         instruction cache (if present).  Fixes problem of cpu caching gdb
  61         breakpoint instructions.
  62
  63         FIXME: PSIM sometimes aborts calling error(), it should instead
  64         call sim_error() say which takes care of housekeeping such as
  65         saving the CIA before calling error.
  66
  67         * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
  68         used when restarting a simulation because the latter has the
  69         unwanted side effect (well I as a kernel hacker think it is) of
  70         performing an isync when the instruction stream doesn't contain
  71         one.
  72
  73 Sun Oct 22 19:27:48 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
  74
  75         * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
  76         monitoring module. Counts both instructions issued and
  77         load/stores.
  78
  79         * NOTE: mon does not contain to count instruction loads as this
  80         information is already available from the mon_issue() hook.
  81
  82         * FIXME: mon doesn't have access to register usage information.
  83         This is needed if the user wants to monitor things like register
  84         stalls.
  85
  86         * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
  87
  88         * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
  89         a common monitor to each of the cpus. Delete
  90         cpu_increment_number_of_insns() and cpu_get_number_of_insns()
  91         replaced by copied code in mon.[hc].
  92
  93 Sun Oct 22 18:42:45 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
  94
  95         * sim_calls.c, main.c, psim.c (psim_create): always create
  96         `WITH_SMP' cpus.  The actual number of CPU's active in a
  97         simulation run is taken from the device node: /init/smp (an
  98         integer). WITH_SMP changed to 2 (remember to put it back to 0).
  99
 100 Fri Oct 20 17:26:54 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 101
 102         * system.c: More system call emulation.  If code appears NetBSD
 103         specific, make conditional to being compiled on a NetBSD system
 104         (sigh).
 105
 106 Wed Oct 18 23:02:20 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 107
 108         * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
 109         lf.[ch](new), table.[ch](new): Split into two generators - igen
 110         that outputs the instruction tables and dgen that outputs the spr
 111         tables.  Add -f (filter out) flag to igen to filter out certain
 112         instructions (ex 64 bit ones) from the created tables.  Include
 113         $(LIBIBERTY_LIB) in link options in case host lacks some libc
 114         functions.
 115
 116         * NOTE: igen, since it was originally written for the
 117         PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
 118
 119         * Makefile.in, std-config.h, ppc-cache-rules(new),
 120         ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
 121         cache-rule and opcode-rule tables from macros found std-config.h.
 122         Delete corresponding macro's from std-config.h.
 123
 124         * FIXME: under this new igen scheme, when playing around with igen
 125         options, you'll find that depenencies don't work very well.
 126
 127         * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
 128         an table of all the instructions.  Code to output a type
 129         enumerating all the instructin names.
 130
 131         * igen.c(lf_print_c_semantic): Move call to increment instruction
 132         counter so that it occures _after_ the instruction has been fully
 133         validated, was double counting illegal/invalid instructions.  Add
 134         conditional so only compiled in when WITH_PROFILE enabled (enabled
 135         by default).
 136
 137         * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
 138         itable.h, count individual instruction types not just total,
 139         adjust reporting functions to output this.
 140
 141         * ppc-instructions (64 bit Load Doubleword with Update Indexed):
 142         Had 32./ instead of 31./
 143
 144         * ppc-instructions (64 bit Store Double Word Conditional Indexed):
 145         bitrot - updated to use newer CR register operators.
 146
 147         * ppc-instructions (64bit Floating Convert from Integer
 148         Doubleword): Correct call to Round_Float().
 149
 150 Mon Oct 16 00:31:20 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 151
 152         * basics.h: #include "sim_callbacks.h" earlier so that its
 153         prototypes are declared in all other header files.
 154
 155         * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
 156         doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
 157         bits.h.
 158
 159         * FIXME: the bits.h/bits.c macro's should be replaced with
 160         (inline) c functions.
 161
 162         * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
 163         Add size of buffer argument to functions writing a string into a
 164         buffer.  Check for buffer overflow.
 165
 166 Sun Oct 15 22:16:11 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 167
 168         * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
 169         of each device.  Make parameter names consistent so macros work.
 170         Use macro's in device functions.
 171
 172         * device_tree.c, devices.h, devices.c: include path to device in a
 173         devices node when creating it.
 174
 175         * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
 176
 177         * core.c: add tracing of core-device, adjust parameter names in
 178         core functions to be consistent with those in devices*.
 179
 180 Sun Oct 15 20:33:20 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 181
 182         * debug.h, debug.c (trace_option): New function. Parses the trace
 183         option, updating the trace array.
 184
 185         * debug.h, debug.c (trace_usage): New function. Outputs the list
 186         of all possible trace options.
 187
 188         * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
 189         parse trace options specified with the simpler -t flag.  Adjust
 190         usage.
 191
 192         * FIXME: basic parsing of command line options is still duplicated
 193         by main.c and sim_calls.c
 194
 195 Thu Oct 26 10:42:28 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 196
 197         * Makefile.in (clean): Delete *.i and *.out files.
 198
 199         * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
 200         macros for either assignment or return.  Fix SWAP_8 to use a
 201         union, and two SWAP_4's.  Delete SWAP_N, since nobody uses it now.
 202         (ENDIAN_N): Add SET argument to SWAP_n calls.  Delete macro defs
 203         that hardwired swapping on/off, let optimizer delete dead code.
 204
 205         * main.c (main): Add printf that we caught a signal and print out
 206         the failing address.
 207
 208 Thu Oct 19 21:43:39 1995  Fred Fish  <fnf@fishfood.amigalib.com>
 209
 210         * Makefile.in:  Remove tabs from otherwise empty line.
 211         Confuses many non-GNU versions of "make".
 212
 213 Wed Oct 18 08:51:25 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 214
 215         * Makefile.in (clean): Delete files produced by gen.
 216
 217 Mon Oct 16 17:34:24 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 218
 219         * gen.c (lf_print_c_semantic_function): Move counting # of
 220         instructions here so it works with caching.
 221         (gen_idecode_c): Move from here.
 222
 223 Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@highland.com.au>
 224
 225         * gen.c, ppc-instructions, psim.c: Fix code for generating
 226         cracking instruction cache.  Delete the code that cached just the
 227         result from doing an instruction lookup - this ran slower than no
 228         cache at all.
 229
 230 Fri Oct 13 09:58:43 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 231
 232         * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
 233
 234         * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
 235         TCL when gdb is linked with the simulator.
 236         * debug.c (ppc_trace): Ditto.
 237         * sim_calls.c (sim_open): Change trace -> ppc_trace.
 238         * main.c (main): Ditto.
 239
 240         * cpu.c (cpu_add_commas): Remove extra static.
 241
 242 Thu Oct 12 11:35:53 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 243
 244         * Makefile.in (psim.o): Now that inlines are turned on, make
 245         psim.o depend on all sources.
 246
 247         * cpu.c (cpu_add_commas): New function to format a long with
 248         commas.
 249         (cpu_print_info): Use it to print number_of_insns.
 250
 251         * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
 252         2, 4, and 8 bytes.
 253         (ENDIAN_N): If both target and host byte orders are known, don't
 254         bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
 255
 256         * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
 257         to allow target specific H2T_n/T2H_n macros to be used.
 258         (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
 259         non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
 260         of the 3 instruction sequence that runs on 386s.
 261
 262         * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
 263         specified on the compile line.
 264         (WITH_BSWAP): If not defined, define as 0.
 265
 266         * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
 267         default inline support.  Pass INLINE_CFLAGS when compiling.
 268
 269         * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
 270         INLINE_DEVICES since GCC doesn't like inline functions that
 271         accept variable arguments.
 272         (stack_ioctl_callback): Make function just static because GCC
 273         doesn't like inline functions that accept variable arguments.
 274
 275         * devices.h (STATIC_DEVICES): Define as empty if not defined.
 276
 277         * inline.c: Correct pathnames of included C files to match current
 278         implementation.
 279
 280         * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
 281         non-zero, define STATIC_DEVICES to be static.
 282
 283         * std-config.h (INLINE): If GNU C and optimizing, define this as
 284         __inline__.
 285         (DEFAULT_INLINE): If not defined, define as 0.
 286         (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
 287         ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
 288         ({SPREG,IDECODE}_INLINE): Ditto.
 289
 290 Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 291
 292         * ppc-instructions: Initial cut of floating point suport added.
 293         Of note include - use of host IEEE floating point instructions,
 294         use of PowerPC manual pseudo code to handle the FPSCR.  It is not
 295         currently a pretty sight.
 296
 297         * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
 298         merge into core.h, core.c, core_n.h. The type memory_map replaced
 299         with core_map.  This removes a level of pointer indirection when
 300         translating an address.
 301
 302         * memory_map.h, memory_map.c, memory_map_n.h: delete.
 303
 304         * Makefile.in et.al (sorry): tweek to use new core, core_map and
 305         core.h.
 306
 307 Wed Oct 11 12:10:26 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 308
 309         * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
 310         most of the other functions in sim_calls.c.
 311
 312         * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
 313         Add macros to better cover up `generic' code.  Makes it possible
 314         to step through the generic code!
 315
 316         * vm.c, vm_n.h, Makefile.in: ditto
 317
 318 Tue Oct 10 15:42:59 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 319
 320         * devices.h, devices.c, memory_map.h, memory_map.c: Changed
 321         callback interface so that there is a read/write buffer but no
 322         read/write_word.  VEA default memory read/write handler sometimes
 323         couldn't resolve an access and of those some were for a memory
 324         fault and some were because gdb was making a bogus request.
 325
 326         * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
 327         eliminate transfer_mode (raw or cooked) parameter from read/write
 328         buffer.
 329
 330 Fri Oct  6 20:23:56 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 331
 332         * ppc-instructions (fmul, fmuls): correct instruction format - had
 333         FRB instead of FRC.
 334
 335 Wed Oct  4 17:31:12 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 336
 337         * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
 338         scand_*): new functions to parse/print fields in device names
 339         while hiding any machine dependency.
 340
 341         * devices.c, psim.c: Change the stack init code so that it is
 342         handled by a device.  Arguments passed across using a device ioctl
 343         (hack).
 344
 345         * devices.h, devices.c: device ioctl callback changed to allow a
 346         variable number of arguments.  This gives greater flexability and
 347         greater chance of bugs.
 348
 349 Tue Oct  3 22:01:56 1995  Andrew Cagney  <cagney@cagney@highland.com.au>
 350
 351         * main.c (printf_filtered, error): Missing va_end() to close off
 352         variable argument use.
 353
 354         * Makefile.in (tmp-gencode): comment out hack to get around some
 355         versions of make not handling files being created as side-effects.
 356
 357         * gen.c (lf_open): Add -n (real_file_name) option.  Specifies an
 358         alternative file name to use in output files for things like #line

 559
 560         * psim/ppc: Re-arange entire directory structure so that
 561         everything lives in the one directory.  While a pain for cleaning,
 562         makes building across multiple architectures much simpler.
 563
 564         * devices.c, device_tree.c: Added code that provides a simple
 565         illustration of how an interrupt control device could be
 566         implemented.
 567
 568         * devices.c: Added code so that the dumb console device can read
 569         (from stdin) as well as write to stdout.
