ec1ff39a5f Splitted memory access methods for 32 and 64-bit code.
The 64-bit code got >10% speedup, the 32-bit code also got about 2% because laddr cacluation optimization

f8c3968d42 Changes list made after CVS service crash:
- Fixed critical bug in CPU code added with one of the prev commits
  - Disasm support for SSE4
  - Rename PNI->SSE3 everywhere in the code
  - Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction
  - Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode
  - Fixed ENTER and LEAVE instructions in x86-64 mode
  - Added ability to turn ON instruction trace, only GUI support is missed.
    Instruction trace could be enabled if Bochs was compiled with disasm
  - More changes Bit32u -> bx_phy_address
  - Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK
  - Small code cleanup
  - Update CHANGES and user docs

024ce249bf Define SMM mode for future implementation.
I would like all next commits be aware of SMM mode.
It can't be implemented right now (too many questions w/o answers) but it will be done till next major release definitelly.

8f0cf91fff This commit is the first commit in long series of changes the have several purposes:
1. Review and commit patch

	[ 896733 ] Lazy flags, for more instructions, only 1 src op

   May be partially, but I hope to get all ideas from patch in

2. Get Bochs speedup after lazy flags optimization

3. Most important for me: improve correctness of emulation by handling several
   undocumented EFLAGS modifications. And finally pass

	UFLAGS - Undefined Flags Test v 3.0
	Copyright (C) Potemkin's Hackers Group (PHG) 1989,1995

   The test still fails on > 50% of its checks.

9b2914fd1d - Temporarily revert Stanislav's changes between 2002-12-18 and 2002-12-19.
Because source files were added/removed it would require an update
  of the windows and macos project files, so I want to wait until after 2.0.
    M Makefile.in         1.51 back to 1.50
    M cpu.h               1.121 back to 1.120
    M fetchdecode.cc      1.37 back to 1.36
    M fetchdecode64.cc    1.33 back to 1.32
    M sse.cc              1.17 back to 1.16
    A sse2.cc             1.27 back to 1.26  (added back)
    R sse_move.cc         removed
    R sse_pfp.cc          removed
- to bring these changes back again, all we have to do is
  "cvs update -j tmp-before1 -j tmp-after1"

a6aa9afd67 - rename "control" to "textconfig". It was named when we called it
a control panel, but now we're calling it a text configuration interface.

5e520261db Add plugin support to Bochs by merging all the changes from the
BRANCH_PLUGINS branch!

Authors:
  Bryce Denney
  Christophe Bothamy
  Kevin Lawton (we grabbed a lot of plugin code from plex86)
Testing help from:
  Volker Ruppert
  Don Becker (Psyon)
  Jeremy Parsons (Br'fin)

The change log is too long to paste in here.  To read the change log, do
  cvs log patches/patch.final-from-BRANCH_PLUGINS.gz

All the changes and a detailed description are contained in a patch
called patch.final-from-BRANCH_PLUGINS.gz.  To look at the complete
patch, do
  cvs upd -r1.1 patches/patch.final-from-BRANCH_PLUGINS.gz

Then you will have a local copy of the patch, which you can gunzip and
play with however you want.

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

5eb4e247bc Merged the final filed ("paging.cc") from Peter Tattam's x86-64
enhancement to bochs.  You can now configure with
--enable-guest2host-tlb.

Force the support of big pages (PSE) when x86-64 is configured.

Reverted back to only one kind of TLB entry style, since everything
is ported.

Fixed one bug in io.cc with as_64 and the index registers.
There are others, as noticed by Peter.

80dd7a07ec Removed references to building libextdb.a. It doesn't seem to
be used at all, and Peter didn't want it.  "extdb.o" is compiled
into libcpu.a, if configured for it.

Removed a few #warnings for x86-64 compile, based on Peter's
line-item comments regarding the warnings I inserted during
the port/merge.
