   2
   3         * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
   4         macros for either assignment or return.  Fix SWAP_8 to use a
   5         union, and two SWAP_4's.  Delete SWAP_N, since nobody uses it now.
   6         (ENDIAN_N): Add SET argument to SWAP_n calls.  Delete macro defs
   7         that hardwired swapping on/off, let optimizer delete dead code.
   8
   9         * main.c (main): Add printf that we caught a signal and print out
  10         the failing address.
  11
  12 Thu Oct 19 21:43:39 1995  Fred Fish  <fnf@fishfood.amigalib.com>
  13
  14         * Makefile.in:  Remove tabs from otherwise empty line.
  15         Confuses many non-GNU versions of "make".
  16
  17 Wed Oct 18 08:51:25 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  18
  19         * Makefile.in (clean): Delete files produced by gen.
  20
  21 Mon Oct 16 17:34:24 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  22
  23         * gen.c (lf_print_c_semantic_function): Move counting # of
  24         instructions here so it works with caching.
  25         (gen_idecode_c): Move from here.
  26
  27 Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@highland.com.au>
  28
  29         * gen.c, ppc-instructions, psim.c: Fix code for generating
  30         cracking instruction cache.  Delete the code that cached just the
  31         result from doing an instruction lookup - this ran slower than no
  32         cache at all.
  33
  34 Fri Oct 13 09:58:43 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  35
  36         * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
  37
  38         * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
  39         TCL when gdb is linked with the simulator.
  40         * debug.c (ppc_trace): Ditto.
  41         * sim_calls.c (sim_open): Change trace -> ppc_trace.
  42         * main.c (main): Ditto.
  43
  44         * cpu.c (cpu_add_commas): Remove extra static.
  45
  46 Thu Oct 12 11:35:53 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  47
  48         * Makefile.in (psim.o): Now that inlines are turned on, make
  49         psim.o depend on all sources.
  50
  51         * cpu.c (cpu_add_commas): New function to format a long with
  52         commas.
  53         (cpu_print_info): Use it to print number_of_insns.
  54
  55         * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
  56         2, 4, and 8 bytes.
  57         (ENDIAN_N): If both target and host byte orders are known, don't
  58         bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
  59
  60         * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
  61         to allow target specific H2T_n/T2H_n macros to be used.
  62         (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
  63         non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
  64         of the 3 instruction sequence that runs on 386s.
  65
  66         * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
  67         specified on the compile line.
  68         (WITH_BSWAP): If not defined, define as 0.
  69
  70         * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
  71         default inline support.  Pass INLINE_CFLAGS when compiling.
  72
  73         * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
  74         INLINE_DEVICES since GCC doesn't like inline functions that
  75         accept variable arguments.
  76         (stack_ioctl_callback): Make function just static because GCC
  77         doesn't like inline functions that accept variable arguments.
  78
  79         * devices.h (STATIC_DEVICES): Define as empty if not defined.
  80
  81         * inline.c: Correct pathnames of included C files to match current
  82         implementation.
  83
  84         * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
  85         non-zero, define STATIC_DEVICES to be static.
  86
  87         * std-config.h (INLINE): If GNU C and optimizing, define this as
  88         __inline__.
  89         (DEFAULT_INLINE): If not defined, define as 0.
  90         (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
  91         ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
  92         ({SPREG,IDECODE}_INLINE): Ditto.
  93
  94 Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@kremvax>
  95
  96         * ppc-instructions: Initial cut of floating point suport added.
  97         Of note include - use of host IEEE floating point instructions,
  98         use of PowerPC manual pseudo code to handle the FPSCR.  It is not
  99         currently a pretty sight.
 100
 101         * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
 102         merge into core.h, core.c, core_n.h. The type memory_map replaced
 103         with core_map.  This removes a level of pointer indirection when
 104         translating an address.
 105
 106         * memory_map.h, memory_map.c, memory_map_n.h: delete.
 107
 108         * Makefile.in et.al (sorry): tweek to use new core, core_map and
 109         core.h.
 110
 111 Wed Oct 11 12:10:26 1995  Andrew Cagney  <cagney@kremvax>
 112
 113         * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
 114         most of the other functions in sim_calls.c.
 115
 116         * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
 117         Add macros to better cover up `generic' code.  Makes it possible
 118         to step through the generic code!
 119
 120         * vm.c, vm_n.h, Makefile.in: ditto
 121
 122 Tue Oct 10 15:42:59 1995  Andrew Cagney  <cagney@kremvax>
 123
 124         * devices.h, devices.c, memory_map.h, memory_map.c: Changed
 125         callback interface so that there is a read/write buffer but no
 126         read/write_word.  VEA default memory read/write handler sometimes
 127         couldn't resolve an access and of those some were for a memory
 128         fault and some were because gdb was making a bogus request.
 129
 130         * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
 131         eliminate transfer_mode (raw or cooked) parameter from read/write
 132         buffer.
 133
 134 Fri Oct  6 20:23:56 1995  Andrew Cagney  <cagney@kremvax>
 135
 136         * ppc-instructions (fmul, fmuls): correct instruction format - had
 137         FRB instead of FRC.
 138
 139 Wed Oct  4 17:31:12 1995  Andrew Cagney  <cagney@kremvax>
 140
 141         * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
 142         scand_*): new functions to parse/print fields in device names
 143         while hiding any machine dependency.
 144
 145         * devices.c, psim.c: Change the stack init code so that it is
 146         handled by a device.  Arguments passed across using a device ioctl
 147         (hack).
 148
 149         * devices.h, devices.c: device ioctl callback changed to allow a
 150         variable number of arguments.  This gives greater flexability and
 151         greater chance of bugs.
 152
 153 Tue Oct  3 22:01:56 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 154
 155         * main.c (printf_filtered, error): Missing va_end() to close off
 156         variable argument use.
 157
 158         * Makefile.in (tmp-gencode): comment out hack to get around some
 159         versions of make not handling files being created as side-effects.
 160
 161         * gen.c (lf_open): Add -n (real_file_name) option.  Specifies an
 162         alternative file name to use in output files for things like #line
 163         macros.
 164
 165         Makefile.in (tmp-gencode): Use gen -n so that debug info is
 166         correct.
 167
 168         * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
 169         Makefile.
 170
 171 Sat Oct  7 22:40:59 1995  Michael Meissner  <meissner@tiktok.cygnus.com>

 188         At present, print the number of instructions executed.
 189
 190         * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
 191         idecode_issue.
 192
 193         * psim.c (psim_print_info): New function to iterate over each of
 194         the CPU's calling cpu_print_info.
 195
 196         * psim.h,cpu.h: Add new declarations.
 197
 198         * sim_calls.c (sim_open): Add argument processing to add the same

 223         if OEA.
 224
 225         * main.c (main): Switch to using getopt.  Make -p also set
 226         trace_semantics.  Make -a turn on all trace flags.  Make -C turn
 227         on console tracing.
 228
 229         * device_tree.c (create_option_device_node): Assume a program is
 230         OEA if the start address is < 4096, not just == 0.
 231
 232 Wed Sep 20 13:36:06 1995  Ian Lance Taylor  <ian@cygnus.com>

 284 Wed Sep  6 00:46:10 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 285
 286         * system.c (system_call): Fix SYS_break - was aligning bss to a
 287         page boundary instead of just an 8 byte one; On first call sbrk(0)
 288         != sbrk(0).
 289
 290 Thu Aug 24 14:48:54 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 291
 292         * Makefile.in (install): Fix install rule.
 293
 294 Tue Aug 22 09:31:18 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 295
 296         * system.c (system_call): Add read support.
 297
 298         * main.c (main): -t sets trace_device_tree.  Correct usage message
 299         to current reality.
 300
 301         * device_tree.c (update_memory_node_for_section): Make tracing
 302         output line up.  If not code or readonly, assume that the section

 305
 306         * core.c (create_core_from_addresses): Print end address in traces
 307         and make tracing output line up.
 308
 309         * Makefile.in: Rewrite from Makefile to work with the Cygnus
 310         environment, and support compiling in a different directory than
 311         the sources reside in.
 312
 313         * ppc-endian.h: Rename from endian.h so that it doesn't get
 314         confused with /usr/include/sys/endian.h on Linux.  Add Linux
 315         endian support.
 316
 317         * ppc-endian.c: Rename to be consistant with ppc-endian.h.
 318         Include ppc-endian.h, not endian.h.
 319
 320         * basics.h (sysdep.h): Include sysdep.h that configure makes.
 321         Include ppc-endian.h, not endian.h.
 322
 323         * std-config.h: Rename from ppc-config.  Put #ifndefs around most
 324         configuration macros, so they can be overridden via CFLAGS.  By
 325         default, turn off tracing.
 326
 327         * configure.in: Clone from other simulator targets.
 328         * configure: Generate via autoconf from configure.in.

 334         * interrupts.c (data_storage_interrupt): allow stack to grow by
 335         upto one MB per increment.
 336
 337         * ppc-instructions: divw was computing rA / rA not rA / rB
 338
 339         * main.c (main): really stupid. Wasn't exiting with correct status
 340
 341 Fri Aug 18 00:38:01 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 342
 343         * system.c (system_call): add system calls kill(2) and getpid(2).
 344
 345         * main.c (main): Check/return exit status when simulation
 346         finishes.
 347
 348 Thu Aug 17 14:29:18 1995  Andrew Cagney  <cagney@kremvax>
 349
 350         * device_tree.c (create_option_device_node): Alignment rules (at
 351         least for the moment) now are for strict alignment only for LE OEA
 352         mode.  (Because of compiler problems).
 353
 354         * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
 355
 356 Thu Aug 17 01:16:38 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 357
 358         * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
 359         forgot to return.
 360
 361         * system.c (system_call): didn't page align break argument before
 362         determining increment break increment.
 363
 364         * psim/ppc: Re-arange entire directory structure so that
 365         everything lives in the one directory.  While a pain for cleaning,
 366         makes building across multiple architectures much simpler.
 367
 368         * devices.c, device_tree.c: Added code that provides a simple
 369         illustration of how an interrupt control device could be
 370         implemented.
 371
 372         * devices.c: Added code so that the dumb console device can read
 373         (from stdin) as well as write to stdout.
