57e1762aa8 - fix register trace output. We want to print 0 or 1 for every boolean
flag, so it needs to call the getB accessor, not the get accessor.

d754550d47 - a boolean variable is represented by just 1 bit, 0=false or 1=true. We have
been using the Boolean type for a number of multi-bit fields on the
  assumption that it is actually many bits wide.  However, this assumption is
  unsafe and has caused some bugs that are hard to track down.
- in the Carbon library on MacOS X, Boolean is defined to be an unsigned char.
  This has been causing some of the EFLAGS accessors to fail (bits 8-31)
  because they depended on Boolean being 32 bits wide.  I changed these
  accessors to return Bit32u instead.  I believe that this will finally fix
  [ 618388 ] Unable to boot under MacOS X.
- It would be possible to create a bochs specific type for booleans (bx_bool),
  but it's cleaner to simply use "Boolean" when we actually mean a 1-bit true
  or false field, and Bit8u/Bit32u when it is a multibit field.

f64eb0e16a Changed the hot countdown timer in pc_system.* files to be
32-bits rather than 64.  This is possible, because there is
  always an active null (heartbeat) timer, with periodicity
  of less than or equal to the maximum 32-bit int value.

  This generates a little less code in the hot part of cpu_loop,
  and saved about 3% execution time on a Win95 boot.

Moved the asynchronous handling code from cpu_loop() to its
  own function since it's a long path.  This neatened up the
  code a little (less gotos and all), and made it more clear
  to use a "while (1)" around the iterative code in cpu_loop().

dbc3fa9220 - make the lowest level functions, put_buffer and get_buffer, into
BX_DEBUGs instead of BX_INFOs so that it's easier to read the higher
  level output.

f54551717e - include <windows.h> in bochs.h whenever WIN32 is defined. This is required
so that windows types can be used in fields, for example in cdrom.h:
    #ifdef WIN32
      HANDLE cdrom_interface::hFile;
    #endif
- since every file includes bochs.h, I removed includes of <windows.h>
  everywhere else
- modified: bochs.h cpu/extdb.cc gui/win32.cc gui/wx.cc iodev/cdrom.cc
  iodev/eth_win32.cc iodev/floppy.cc

8e33d2eda1 Integrated patches/patch.extra_eflags_asms from Jas, for more asm()
coverage of the high-frequency eflags instructions.  That should
  complete the asm() eflags updates for now, as we should be stabilizing
  moving towards bochs 2.0.

f344c3df8d Added patch from Jas Sandys-Lumsdaine. I'll review this soon and
integrate it, if it looks good.  Putting here for the CVS trail.

  "This patch adds extra inline asm statements for the most important
  instructions I found to be still resorting to lazy flags execution.
  I counted the instructions that "hit" and "missed" when an eflag
  value was needed - if there was a miss, the flag was not known and
  had to be calculated with lazy_flags.cc. The culprit instruction
  which last executed to affect the eflags was tallied."

ee47fabac0 Committed new bochs internal timers (in pc_system.{cc,h}.
These seem to be working better, are a more simple design,
  easier to understand, and AFAIK don't have race conditions
  in them like the old ones do.

Re-coded the apic timer, to return cycle accurate values
  which vary with each iteration of a read from a guest OS.
  The previous implementation had very poor resolution.  It
  also didn't check the mask bit to see if an apic timer
  interrupt should occur on countdown to 0.  The apic timer
  now calls its own bochs timer, rather than tag on the
  one in iodev/devices.cc.

I needed to use one new function which is an inline in
  pc_sytem.h.  That would have to be added to the old pc_system.h if
  we have to back-out to it.

Linux/x86-64 now boots until it hits two undefined opcodes:

  FXRSTOR (0f ae).  This restores FPU, MMX, XMM and MXCSR registers
    from a 512-byte region of memory.  We don't implement this yet.

  MOVNTDQ (66 0f e7).  This is a move involving an XMM register.
    The 0x66 prefix is used so it's a double quadword, rather than
    MOVNTQ (0f e7) which operates on a single quadword.

  The Linux kernel panic is on the MOVNTQD opcodes.  Perhaps that's
  because that opcode is used in exception handling of the 1st?

  Looks like we need to implement some new instructions.

f3b7378307 - added multiple cdrom support for win32 (NT/2000 version untested). The ASPI
version uses the cdrom drives in the system's order. Drive letters are not
  used by ASPI.
- wrong BX_INFO message for ASPI disabled. The version number is never checked.

de68ca74d9 - call BX_CPU_C::set_INTR(0) instead of just setting the INTR value.
The result is the async_event gets set, though as far as I can tell
  it makes no difference.

1aeb4c71b1 Updated the alternate pc_system.{cc,h} files to add the ID string
parameter so we know which source modules are requesting
  timers.  Also added a SpewPeriodicTimerInfo #define in
  case somebody is still having guest OS hang problems.  If
  enabled, this macro will force a brief dump of the active timers
  list to the bochsout.txt file, every 5Million ticks.
  If the lowest timer's period is extremely low, that would be
  suspect.

83c9d266d0 Added a field on register_timer() so that a name identifying the
requesting source can be registered as well.  Otherwise, there
  is no way to know which source modules are requesting
  suspect frequencies which are too high.

4c9776fb96 - add -lwinmm to the link lines anytime you use --enable-sb16=win. Now
instead of winmm being a part of GUI_LINK_OPTS_WIN32 only, it is
  placed in @DEVICE_LINE_OPTS@ so that it will be used for sdl, rfb, wx,
  etc.
- solve compile problems when building bximage, niclist, and any other
  console based program.  The compile flags returned by wx-config and
  sdl-config did strange things to these console programs, for example
  redefining main to SDL_main.  Because I wanted to use the
  configure-generated CFLAGS to compile the programs, but I wanted to
  avoid including GUI specific compile options, I split up the configure's
  @CFLAGS@ variable into @CFLAGS@ and @GUI_CFLAGS@, and split
  @CXXFLAGS@ into @CXXFLAGS@ and @GUI_CXXFLAGS@.  All programs in the
  Bochs binary will use both, but the console programs will just use
  @CFLAGS@ or @CXXFLAGS@.
- gui/Makefile.in, I no longer use the gui specific CFLAGS variables,
  SDL_CFLAGS and WX_CXXFLAGS.  These values are included in CFLAGS and
  CXXFLAGS now.
- modified: configure.in, configure, all Makefile.in's

0d8e31b672 - solve SDL specific build problem: in win32, SDL redefines main to SDL_main.
Include SDL.h so that the C language prototype can be found.  Otherwise
  SDL_main() will get its name mangled and not match what the SDL library is
  expecting.

a11e637ec0 Added an alternative set of pc_system.{cc,h} files for
testing.  Please try these out if you want to help test
  them or if your guest OS appears to be hanging with
  no apparent activity.  The old bochs internal timer
  framework is broken in several areas.

  I put these in the patches directory for now.  After
  a 'make all-clean', you can do something like:

    mv pc_system.cc pc_system.cc-old
    mv pc_system.h  pc_system.h-old
    cp patches/pc_system.cc-kpl .
    cp patches/pc_system.h-kpl .
    make

  And let me know if A) they work for you and B) if they help
  the hanging problem.
