Correct shift count for 32 bit shift instructions. Correct sign
extension for arithmetic shifts to not shift the number of bits in
the type. Fix 64 bit multiply high word calculation. Fix 32 bit
unsigned multiply. Fix ldxc1 and friends to use coprocessor 1.
Fix madd.
* interp.c (CHECKHILO): Don't set HIACCESS, LOACCESS, or HLPC.
It's OK to have a mult follow a mult. What's not OK is to have a
mult follow an mfhi.
(Convert): Comment out incorrect rounding code.
Mon Sep 16 11:38:16 1996 James G. Smith <jsmith@cygnus.co.uk>
* interp.c (sim_monitor): Improved monitor printf
simulation. Tidied up simulator warnings, and added "--log" option
for directing warning message output.

Thu Aug 22 15:03:12 1996 Ian Lance Taylor <ian@cygnus.com>
* Makefile.in (gencode): Depend upon gencode.o, getopt.o, and
getopt1.o, rather than on gencode.c. Link objects together.
Don't link against -liberty.

* gencode.c: Include <ctype.h> and "ansidecl.h".
(AND): Undefine after including "ansidecl.h".
(ULONG_MAX): Define if not defined.
(OP_*): Don't define macros; now defined in opcode/mips.h.
(main): Call my_strtoul rather than strtoul.
(my_strtoul): New static function.
Wed Jul 17 18:12:38 1996 Stu Grossman (grossman@critters.cygnus.com)
* gencode.c (process_instructions): Generate word64 and uword64
instead of `long long' and `unsigned long long' data types.
* interp.c: #include sysdep.h to get signals, and define default
for SIGBUS.
* (Convert): Work around for Visual-C++ compiler bug with type
conversion.
* support.h: Make things compile under Visual-C++ by using
__int64 instead of `long long'. Change many refs to long long
into word64/uword64 typedefs.
