   2
   3         * erc32.c (port_init):  Disable this for __GO32__ (got no pty's
   4         there either...).

   6 Mon Aug 12 17:04:58 1996  Stu Grossman  (grossman@critters.cygnus.com)
   7
   8         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
   9         necessary.
  10         * (port_init):  Don't even *try* to open pty's under _WIN32.
  11         * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
  12         * float.c:  Get rid of #warning.  Makes Microsoft C barf.
  13         * interf.c (sim_open):  Cast fprintf to (fprintf_ftype) to fix
  14         compiler warning.
  15         * (sim_load sim_create_inferior sim_read):  Use prototypes only in
  16         decls, not defs.
  17         * Get rid of enum sim_stop.  It's defined in remote-sim.h.
  18         * (sim_stop_reason):  Define SIGTRAP if _WIN32.
  19         * sis.h:  Include ansidecl.h and remote-sim.h.

  21 Wed Jul  3 16:05:23 1996  Stu Grossman  (grossman@critters.cygnus.com)
  22
  23         * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
  24         sis.h:  Get rid of all uses of long long's.
  25         * (close_port read_uart write_uart uarta_tx):  Don't seg fault
  26         when can't open pty's.
  27         * exec.c:  Add two new instructions: smul, and divscc.
  28         * interf.c (flush_windows):  New routine to flush the register
  29         windows out to the stack just before returning to GDB.  Makes
  30         backtraces work much better.

  32 Wed Jun 26 12:19:11 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
  33
  34         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
  35         INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
  36         (docdir, oldincludedir): Removed.
  37         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
  38         (AC_PROG_INSTALL): Added.
  39         * configure: Rebuilt.
  40
  41 Mon Jun 24 14:19:07 1996  Ian Lance Taylor  <ian@cygnus.com>
  42
  43         * configure.in: Call AC_PROG_CC before running configure.host.
  44         * configure: Rebuild with autoconf 2.10.
  45
  46 Tue Jun  4 10:37:12 1996  Tom Tromey  <tromey@csk3.cygnus.com>
  47
  48         * Makefile.in (install): Don't check to see if tooldir exists.
  49         Make $(tooldir) and $(tooldir)/bin.
  50
  51 Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>
  52
  53         * Makefile.in (end.h): Use explicit ./ when running end.
  54
  55 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
  56
  57         * func.c(bfd_load): Don't try to print the filename if the pfbd is
  58         NULL.
  59         * interf.c(sim_load): Pass the whole string, not just the first
  60         byte.
  61
  62 Version 2.1 26-02-96
  63 --------------------
  64
  65 * Fixed bug in "go" command.
  66
  67 version 2.0 05-02-96
  68 --------------------
  69
  70 * Fixed bug in interrupt force register (erc32.c).
  71
  72 * Change file load function to use bfd_openr.
  73
  74 * SIS should now be endian independent.
  75
  76 version 1.8 24-11-95
  77 --------------------
  78
  79 * Fixed FPU timing - some sequences of FPU instructions did not calculate
  80   the resource dependencies right.
  81
  82 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
  83   but no FPU trap is generated.
  84
  85 version 1.7.1 31-10-95
  86 --------------------
  87
  88 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
  89   the FPU stays in execute mode.
  90
  91 * Corrected JMPL and RETT timing (these instructions takes two cycles).
  92
  93
  94 version 1.7 25-10-95
  95 --------------------
  96
  97 * Interrupt during annuled instruction corrupted return address - fixed.
  98
  99
 100 version 1.6.2 25-10-95
 101 --------------------
 102
 103 * Added -DFAST_UART to Makefile
 104
 105
 106 version 1.6.1 24-10-95
 107 --------------------
 108
 109 * Fixed bug in STDFQ which caused bus error
 110
 111
 112 version 1.6 02-10-95
 113 --------------------
 114
 115 * Modified srt0.s to include code that initiates registers in IU and FPU
 116   and initializes the data segment. The simulator 'load' command does not
 117   longer initialize the data segment!
 118
 119 * Corrected MEC timer operation; scalers now divide the frequency by
 120   (scaler_value + 1).
 121
 122 * MEC breakpoints are not checked during store operation
 123
 124
 125 version 1.5 14-09-95
 126 --------------------
 127
 128 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 129
 130 * Fixed bug that allowed an annuled instruction to cause memory exception.
 131
 132 * The *ws parameter in mem.c should now contain the number of waitstates
 133   required by the memory access (was total number of cycles).
 134
 135 * The supplied srt0.s now clears the BSS (thanks Joel).
 136
 137 version 1.4 22-08-95
 138 --------------------
 139
 140 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 141 some problems on solaris 2.x machines.
 142
 143 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 144 may suffer a bit ...
 145
 146 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 147
 148 version 1.3 26-07-95
 149 --------------------
 150
 151 * Fixed bug in mulscc instruction (how could that ever have worked?)
 152
 153 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 154
 155 version 1.2 13-07-95
 156 --------------------
 157
 158 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 159 one interrupt pending)
 160
 161 * Fixed updating of condition codes during logical instructions (carry and
 162 overflow were not reset)
 163
 164 * Fixed bug in WRTBR (tt field was wrongly over-written)
 165
 166 version 1.1 07-07-95
 167 --------------------
 168
 169 * Fixed several bugs in the interrupt handler and callback routines.
 170 (reported by Paul Warren, Alsys)
