sim/mips/ChangeLog

   1 Thu Sep 19 15:34:17 1996  Ian Lance Taylor  <ian@cygnus.com>
   2
   3         * interp.c (CHECKHILO): Don't set HIACCESS, LOACCESS, or HLPC.
   4         It's OK to have a mult follow a mult.  What's not OK is to have a
   5         mult follow an mfhi.
   6
   7         * gencode.c (process_instructions): Correct handling of nor
   8         instruction.  Correct shift count for 32 bit shift instructions.
   9         Correct sign extension for arithmetic shifts to not shift the
  10         number of bits in the type.
  11
  12 Mon Sep 16 11:38:16 1996  James G. Smith  <jsmith@cygnus.co.uk>
  13
  14         * interp.c (sim_monitor): Improved monitor printf
  15         simulation. Tidied up simulator warnings, and added "--log" option
  16         for directing warning message output.
  17         * gencode.c: Use sim_warning() rather than WARNING macro.
  18
  19 Thu Aug 22 15:03:12 1996  Ian Lance Taylor  <ian@cygnus.com>
  20
  21         * Makefile.in (gencode): Depend upon gencode.o, getopt.o, and
  22         getopt1.o, rather than on gencode.c.  Link objects together.
  23         Don't link against -liberty.
  24         (gencode.o, getopt.o, getopt1.o): New targets.
  25         * gencode.c: Include <ctype.h> and "ansidecl.h".
  26         (AND): Undefine after including "ansidecl.h".
  27         (ULONG_MAX): Define if not defined.
  28         (OP_*): Don't define macros; now defined in opcode/mips.h.
  29         (main): Call my_strtoul rather than strtoul.
  30         (my_strtoul): New static function.

  32 Wed Jul 17 18:12:38 1996  Stu Grossman  (grossman@critters.cygnus.com)
  33
  34         * gencode.c (process_instructions):  Generate word64 and uword64
  35         instead of `long long' and `unsigned long long' data types.
  36         * interp.c:  #include sysdep.h to get signals, and define default
  37         for SIGBUS.
  38         * (Convert):  Work around for Visual-C++ compiler bug with type
  39         conversion.
  40         * support.h:  Make things compile under Visual-C++ by using
  41         __int64 instead of `long long'.  Change many refs to long long
  42         into word64/uword64 typedefs.
