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

ab6b9c7dcb New table-based disassembler:
* Fully supports
	* MMX/XMM/3DNOW instruction sets
	* FPU instruction
	* SSE3 extensions
 currently only 16/32 bit mode bug anyway, it is much better that old one ;)

c4782d5e9c - apply patches/patch.disasm-luizshiguno from Luiz Henrique Shigunov.
From the author:

  I've implemented functions ALOb(), ObAL(), YbAL(),
  ALXb() and eAXXv() from dis_groups.cc.

  I've also changed dis_decode.cc to print cmpsd if code
  is 32 bits and cmpsw if code is 16 bits. The same with
  stosd, lodsd and scasd.

0a7cb3a43c - apply patch.ifdef-disabled-options. Comments from that patch are below:
For a whole lot of configure options, I put #if...#endif around code that
  is specific to the option, even in files which are normally only compiled
  when the option is on.  This allows me to create a MS Visual C++ 6.0
  workspace that supports many of these options.  The workspace will basically
  compile every file all the time, but the code for disabled options will
  be commented out by the #if...#endif.

  This may one day lead to simplification of the Makefiles and configure
  scripts, but for the moment I'm leaving Makefiles and configure scripts
  alone.

  Affected options:
    BX_SUPPORT_APIC (cpu/apic.cc)
    BX_SUPPORT_X86_64 (cpu/*64.cc)
    BX_DEBUGGER (debug/*)
    BX_DISASM (disasm/*)
    BX_WITH_nameofgui (gui/*)
    BX_SUPPORT_CDROM (iodev/cdrom.cc)
    BX_NE2K_SUPPORT (iodev/eth*.cc, iodev/ne2k.cc)

cec9135e9f - Apply patch.replace-Boolean rev 1.3. Every "Boolean" is now changed to a
"bx_bool" which is always defined as Bit32u on all platforms.  In Carbon
  specific code, Boolean is still used because the Carbon header files
  define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
  The bug was that some code in Bochs depends on Boolean to be a
  32 bit value.  (This should be fixed, but I don't know all the places
  where it needs to be fixed yet.)  Because Carbon defined Boolean as
  an unsigned char, Bochs just followed along and used the unsigned char
  definition to avoid compile problems.  This exposed the dependency
  on 32 bit Boolean on MacOS X only and led to major simulation problems,
  that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
  our own type.  I chose bx_bool for several reasons.
  1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
     platforms, which makes it much less likely to have more platform-specific
     simulation differences in the future.  (I spent hours on a borrowed
     MacOSX machine chasing bug 618388 before discovering that different sized
     Booleans were the problem, and I don't want to repeat that.)
  2. We still have at least one dependency on 32 bit Booleans which must be
     fixed some time, but I don't want to risk introducing new bugs into the
     simulation just before the 2.0 release.

3ed1d61cd4 Initial work on updating bochs disassembler
Used patch.disasm to do

1) clean up the disasm output to make the dispaly of extra stuff optional.
2) included the part of the patch which displays displacements as
   proper addresses.

e61d00351f - merged BRANCH-smp-bochs into main branch. For details see comments
in BRANCH-smp-bochs revisions.
- The general task was to make multiple CPU's which communicate
  through their APICs.  So instead of BX_CPU and BX_MEM, we now have
  BX_CPU(x) and BX_MEM(y).  For an SMP simulation you have several
  processors in a shared memory space, so there might be processors
  BX_CPU(0..3) but only one memory space BX_MEM(0).  For cosimulation,
  you could have BX_CPU(0) with BX_MEM(0), then BX_CPU(1) with
  BX_MEM(1).  WARNING: Cosimulation is almost certainly broken by the
  SMP changes.
- to simulate multiple CPUs, you have to give each CPU time to execute
  in turn.  This is currently implemented using debugger guards.  The
  cpu loop steps one CPU for a few instructions, then steps the
  next CPU for a few instructions, etc.
- there is some limited support in the debugger for two CPUs, for
  example printing information from each CPU when single stepping.

bdb89cd364 merge in BRANCH-io-cleanup.
To see the commit logs for this use either cvsweb or
cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files.

In general this provides a generic interface for logging.

logfunctions:: is a class that is inherited by some classes, and also
.   allocated as a standalone global called 'genlog'.  All logging uses
.   one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this
.   class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros
.   respectively.
.
.   An example usage:
.     BX_INFO(("Hello, World!\n"));

iofunctions:: is a class that is allocated once by default, and assigned
as the iofunction of each logfunctions instance.  It is this class that
maintains the file descriptor and other output related code, at this
point using vfprintf().  At some future point, someone may choose to
write a gui 'console' for bochs to which messages would be redirected
simply by assigning a different iofunction class to the various logfunctions
objects.

More cleanup is coming, but this works for now.  If you want to see alot
of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1.
