   2
   3         * Makefile.in (clean): Delete *.i and *.out files.
   4
   5         * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
   6         macros for either assignment or return.  Fix SWAP_8 to use a
   7         union, and two SWAP_4's.  Delete SWAP_N, since nobody uses it now.
   8         (ENDIAN_N): Add SET argument to SWAP_n calls.  Delete macro defs
   9         that hardwired swapping on/off, let optimizer delete dead code.
  10
  11         * main.c (main): Add printf that we caught a signal and print out
  12         the failing address.
  13
  14 Thu Oct 19 21:43:39 1995  Fred Fish  <fnf@fishfood.amigalib.com>
  15
  16         * Makefile.in:  Remove tabs from otherwise empty line.
  17         Confuses many non-GNU versions of "make".
  18
  19 Wed Oct 18 08:51:25 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  20
  21         * Makefile.in (clean): Delete files produced by gen.
  22
  23 Mon Oct 16 17:34:24 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  24
  25         * gen.c (lf_print_c_semantic_function): Move counting # of
  26         instructions here so it works with caching.
  27         (gen_idecode_c): Move from here.
  28
  29 Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@highland.com.au>
  30
  31         * gen.c, ppc-instructions, psim.c: Fix code for generating
  32         cracking instruction cache.  Delete the code that cached just the
  33         result from doing an instruction lookup - this ran slower than no
  34         cache at all.
  35
  36 Fri Oct 13 09:58:43 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  37
  38         * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
  39
  40         * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
  41         TCL when gdb is linked with the simulator.
  42         * debug.c (ppc_trace): Ditto.
  43         * sim_calls.c (sim_open): Change trace -> ppc_trace.
  44         * main.c (main): Ditto.
  45
  46         * cpu.c (cpu_add_commas): Remove extra static.
  47
  48 Thu Oct 12 11:35:53 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  49
  50         * Makefile.in (psim.o): Now that inlines are turned on, make
  51         psim.o depend on all sources.
  52
  53         * cpu.c (cpu_add_commas): New function to format a long with
  54         commas.
  55         (cpu_print_info): Use it to print number_of_insns.
  56
  57         * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
  58         2, 4, and 8 bytes.
  59         (ENDIAN_N): If both target and host byte orders are known, don't
  60         bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
  61
  62         * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
  63         to allow target specific H2T_n/T2H_n macros to be used.
  64         (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
  65         non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
  66         of the 3 instruction sequence that runs on 386s.
  67
  68         * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
  69         specified on the compile line.
  70         (WITH_BSWAP): If not defined, define as 0.
  71
  72         * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
  73         default inline support.  Pass INLINE_CFLAGS when compiling.
  74
  75         * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
  76         INLINE_DEVICES since GCC doesn't like inline functions that
  77         accept variable arguments.
  78         (stack_ioctl_callback): Make function just static because GCC
  79         doesn't like inline functions that accept variable arguments.
  80
  81         * devices.h (STATIC_DEVICES): Define as empty if not defined.
  82
  83         * inline.c: Correct pathnames of included C files to match current
  84         implementation.
  85
  86         * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
  87         non-zero, define STATIC_DEVICES to be static.
  88
  89         * std-config.h (INLINE): If GNU C and optimizing, define this as
  90         __inline__.
  91         (DEFAULT_INLINE): If not defined, define as 0.
  92         (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
  93         ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
  94         ({SPREG,IDECODE}_INLINE): Ditto.
  95
  96 Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@kremvax>
  97
  98         * ppc-instructions: Initial cut of floating point suport added.
  99         Of note include - use of host IEEE floating point instructions,
 100         use of PowerPC manual pseudo code to handle the FPSCR.  It is not
 101         currently a pretty sight.
 102
 103         * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
 104         merge into core.h, core.c, core_n.h. The type memory_map replaced
 105         with core_map.  This removes a level of pointer indirection when
 106         translating an address.
 107
 108         * memory_map.h, memory_map.c, memory_map_n.h: delete.
 109
 110         * Makefile.in et.al (sorry): tweek to use new core, core_map and
 111         core.h.
 112
 113 Wed Oct 11 12:10:26 1995  Andrew Cagney  <cagney@kremvax>
 114
 115         * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
 116         most of the other functions in sim_calls.c.
 117
 118         * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
 119         Add macros to better cover up `generic' code.  Makes it possible
 120         to step through the generic code!
 121
 122         * vm.c, vm_n.h, Makefile.in: ditto
 123
 124 Tue Oct 10 15:42:59 1995  Andrew Cagney  <cagney@kremvax>
 125
 126         * devices.h, devices.c, memory_map.h, memory_map.c: Changed
 127         callback interface so that there is a read/write buffer but no
 128         read/write_word.  VEA default memory read/write handler sometimes
 129         couldn't resolve an access and of those some were for a memory
 130         fault and some were because gdb was making a bogus request.
 131
 132         * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
 133         eliminate transfer_mode (raw or cooked) parameter from read/write
 134         buffer.
 135
 136 Fri Oct  6 20:23:56 1995  Andrew Cagney  <cagney@kremvax>
 137
 138         * ppc-instructions (fmul, fmuls): correct instruction format - had
 139         FRB instead of FRC.
 140
 141 Wed Oct  4 17:31:12 1995  Andrew Cagney  <cagney@kremvax>
 142
 143         * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
 144         scand_*): new functions to parse/print fields in device names
 145         while hiding any machine dependency.
 146
 147         * devices.c, psim.c: Change the stack init code so that it is
 148         handled by a device.  Arguments passed across using a device ioctl
 149         (hack).
 150
 151         * devices.h, devices.c: device ioctl callback changed to allow a
 152         variable number of arguments.  This gives greater flexability and
 153         greater chance of bugs.
 154
 155 Tue Oct  3 22:01:56 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 156
 157         * main.c (printf_filtered, error): Missing va_end() to close off
 158         variable argument use.
 159
 160         * Makefile.in (tmp-gencode): comment out hack to get around some
 161         versions of make not handling files being created as side-effects.
 162
 163         * gen.c (lf_open): Add -n (real_file_name) option.  Specifies an
 164         alternative file name to use in output files for things like #line
 165         macros.
 166
 167         Makefile.in (tmp-gencode): Use gen -n so that debug info is
 168         correct.
 169
 170         * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
 171         Makefile.
 172
 173 Sat Oct  7 22:40:59 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 174

 191
 192         * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
 193         idecode_issue.
 194
 195         * psim.c (psim_print_info): New function to iterate over each of
 196         the CPU's calling cpu_print_info.
 197
 198         * psim.h,cpu.h: Add new declarations.
 199

 228         trace_semantics.  Make -a turn on all trace flags.  Make -C turn
 229         on console tracing.
 230
 231         * device_tree.c (create_option_device_node): Assume a program is

 287
 288         * system.c (system_call): Fix SYS_break - was aligning bss to a
 289         page boundary instead of just an 8 byte one; On first call sbrk(0)
 290         != sbrk(0).
 291
 292 Thu Aug 24 14:48:54 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 293
 294         * Makefile.in (install): Fix install rule.

 307
 308         * core.c (create_core_from_addresses): Print end address in traces
 309         and make tracing output line up.

 312         environment, and support compiling in a different directory than
 313         the sources reside in.
 314
 315         * ppc-endian.h: Rename from endian.h so that it doesn't get
 316         confused with /usr/include/sys/endian.h on Linux.  Add Linux
 317         endian support.
 318
 319         * ppc-endian.c: Rename to be consistant with ppc-endian.h.
 320         Include ppc-endian.h, not endian.h.
 321
 322         * basics.h (sysdep.h): Include sysdep.h that configure makes.
 323         Include ppc-endian.h, not endian.h.
 324
 325         * std-config.h: Rename from ppc-config.  Put #ifndefs around most
 326         configuration macros, so they can be overridden via CFLAGS.  By

 337         upto one MB per increment.
 338
 339         * ppc-instructions: divw was computing rA / rA not rA / rB
 340
 341         * main.c (main): really stupid. Wasn't exiting with correct status
 342
 343 Fri Aug 18 00:38:01 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 344
 345         * system.c (system_call): add system calls kill(2) and getpid(2).

 347         * main.c (main): Check/return exit status when simulation
 348         finishes.
 349
 350 Thu Aug 17 14:29:18 1995  Andrew Cagney  <cagney@kremvax>
 351
 352         * device_tree.c (create_option_device_node): Alignment rules (at
 353         least for the moment) now are for strict alignment only for LE OEA
 354         mode.  (Because of compiler problems).
 355
 356         * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
 357
 358 Thu Aug 17 01:16:38 1995  Andrew Cagney - aka Noid  <cagney@kremvax>

 361         forgot to return.
 362
 363         * system.c (system_call): didn't page align break argument before
 364         determining increment break increment.

 366         * psim/ppc: Re-arange entire directory structure so that
 367         everything lives in the one directory.  While a pain for cleaning,
 368         makes building across multiple architectures much simpler.
 369
 370         * devices.c, device_tree.c: Added code that provides a simple
 371         illustration of how an interrupt control device could be
 372         implemented.
 373
 374         * devices.c: Added code so that the dumb console device can read
 375         (from stdin) as well as write to stdout.
