   6
   7         * Makefile.in (CC_FOR_BUILD): New variable.
   8         (AR, AR_FLAGS, BISON, MAKEINFO): Remove duplicate variables.
   9         (RANLIB, CC): Likewise.
  10         (end): Use $(CC_FOR_BUILD), not $(CC).

  14 Sun Sep  8 14:04:37 1996  Stu Grossman  (grossman@critters.cygnus.com)
  15
  16         * erc32.c (port_init):  Disable this for __GO32__ (got no pty's
  17         there either...).
  18
  19 Mon Aug 12 17:04:58 1996  Stu Grossman  (grossman@critters.cygnus.com)
  20
  21         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
  22         necessary.
  23         * (port_init):  Don't even *try* to open pty's under _WIN32.
  24         * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
  25         * float.c:  Get rid of #warning.  Makes Microsoft C barf.
  26         * interf.c (sim_open):  Cast fprintf to (fprintf_ftype) to fix
  27         compiler warning.
  28         * (sim_load sim_create_inferior sim_read):  Use prototypes only in
  29         decls, not defs.
  30         * Get rid of enum sim_stop.  It's defined in remote-sim.h.
  31         * (sim_stop_reason):  Define SIGTRAP if _WIN32.
  32         * sis.h:  Include ansidecl.h and remote-sim.h.
  33
  34 Wed Jul  3 16:05:23 1996  Stu Grossman  (grossman@critters.cygnus.com)
  35
  36         * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
  37         sis.h:  Get rid of all uses of long long's.
  38         * (close_port read_uart write_uart uarta_tx):  Don't seg fault
  39         when can't open pty's.
  40         * exec.c:  Add two new instructions: smul, and divscc.
  41         * interf.c (flush_windows):  New routine to flush the register
  42         windows out to the stack just before returning to GDB.  Makes
  43         backtraces work much better.
  44
  45 Wed Jun 26 12:19:11 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
  46
  47         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
  48         INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
  49         (docdir, oldincludedir): Removed.
  50         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
  51         (AC_PROG_INSTALL): Added.
  52         * configure: Rebuilt.
  53
  54 Mon Jun 24 14:19:07 1996  Ian Lance Taylor  <ian@cygnus.com>
  55
  56         * configure.in: Call AC_PROG_CC before running configure.host.
  57         * configure: Rebuild with autoconf 2.10.
  58
  59 Tue Jun  4 10:37:12 1996  Tom Tromey  <tromey@csk3.cygnus.com>
  60
  61         * Makefile.in (install): Don't check to see if tooldir exists.
  62         Make $(tooldir) and $(tooldir)/bin.
  63
  64 Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>
  65
  66         * Makefile.in (end.h): Use explicit ./ when running end.
  67
  68 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
  69
  70         * func.c(bfd_load): Don't try to print the filename if the pfbd is
  71         NULL.
  72         * interf.c(sim_load): Pass the whole string, not just the first
  73         byte.
  74
  75 Version 2.1 26-02-96
  76 --------------------
  77
  78 * Fixed bug in "go" command.
  79
  80 version 2.0 05-02-96
  81 --------------------
  82
  83 * Fixed bug in interrupt force register (erc32.c).
  84
  85 * Change file load function to use bfd_openr.
  86
  87 * SIS should now be endian independent.
  88
  89 version 1.8 24-11-95
  90 --------------------
  91
  92 * Fixed FPU timing - some sequences of FPU instructions did not calculate
  93   the resource dependencies right.
  94
  95 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
  96   but no FPU trap is generated.
  97
  98 version 1.7.1 31-10-95
  99 --------------------
 100
 101 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 102   the FPU stays in execute mode.
 103
 104 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 105
 106
 107 version 1.7 25-10-95
 108 --------------------
 109
 110 * Interrupt during annuled instruction corrupted return address - fixed.
 111
 112
 113 version 1.6.2 25-10-95
 114 --------------------
 115
 116 * Added -DFAST_UART to Makefile
 117
 118
 119 version 1.6.1 24-10-95
 120 --------------------
 121
 122 * Fixed bug in STDFQ which caused bus error
 123
 124
 125 version 1.6 02-10-95
 126 --------------------
 127
 128 * Modified srt0.s to include code that initiates registers in IU and FPU
 129   and initializes the data segment. The simulator 'load' command does not
 130   longer initialize the data segment!
 131
 132 * Corrected MEC timer operation; scalers now divide the frequency by
 133   (scaler_value + 1).
 134
 135 * MEC breakpoints are not checked during store operation
 136
 137
 138 version 1.5 14-09-95
 139 --------------------
 140
 141 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 142
 143 * Fixed bug that allowed an annuled instruction to cause memory exception.
 144
 145 * The *ws parameter in mem.c should now contain the number of waitstates
 146   required by the memory access (was total number of cycles).
 147
 148 * The supplied srt0.s now clears the BSS (thanks Joel).
 149
 150 version 1.4 22-08-95
 151 --------------------
 152
 153 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 154 some problems on solaris 2.x machines.
 155
 156 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 157 may suffer a bit ...
 158
 159 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 160
 161 version 1.3 26-07-95
 162 --------------------
 163
 164 * Fixed bug in mulscc instruction (how could that ever have worked?)
 165
 166 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 167
 168 version 1.2 13-07-95
 169 --------------------
 170
 171 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 172 one interrupt pending)
 173
 174 * Fixed updating of condition codes during logical instructions (carry and
 175 overflow were not reset)
 176
 177 * Fixed bug in WRTBR (tt field was wrongly over-written)
 178
 179 version 1.1 07-07-95
 180 --------------------
 181
 182 * Fixed several bugs in the interrupt handler and callback routines.
 183 (reported by Paul Warren, Alsys)
