767fb77ebd Fully handle segment limits inside prefetch method.
1. Should speed up the simulation (eliminate seg.limit check per every instruction exec)
2. Should help for DT (h.johansson request)

ff02bc8ef0 Fixed:
With cvs snapshot 2006-04-09, --enable-debugger does not show the executed instructions anymore after being enabled via iodebug or "trace on".

d972e4a4b7 Fixed CR3 restore in RSM instruction
Added HALT state indication (actually make existant one working for single CPU)

45f30f0a4c some code written to enter CPU to shutdown state.
finally the shutdown handling should be done exactly as in VmWare - the GUI should ask user if the CPU should reset and go to HLT/IF=0 if user choosed to stay in shutdown mode.
CPU configure option reset-on-triple-failt should be extended to shutdown-reset=0|1
small code cleanups and fixes

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

d6f85c12f6 NMI support inside the CPU.
Added two functions to query NMI and SMI from Bochs debugger.
In future they could be used for generating NMI or SMI by user request using GUI button (could be implemented separatelly later and under configure-time or .bocshrc option)

e85a90a720 Remove cpu.h -> devices.cc dependancy, kill_bochs_request moved from CPU to bx_pc_system

7b6c2587a9 Now devices could be compiled separatelly from CPU
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...

203a9caf31 SMM mode could leave together with pmode or any other (according to amd docs)
so we need separate bx_bool indicator in_smm instead

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.

37eb82c69c Totally remove the cosimulation code from Bochs.
The Bochs anyway even doesn't compile if cosimulation configured enabled.
But in the same time the cosimulation code only disturbs to the future development of Bochs debugger, for example adding x86-64 functionality ...
For those of you who still may want to see the cosimulation code inside I put it in patch and upload it Bochs CVS patches folder. Read comments for the patch ! ----------------------------------------------------------------------

18afa9fd2d This is cumulative patch for bochs debugger, it is only very first step towards working debugger supporting all new simulator functionalitieS.
- move crc.cc from debugger to bochs folder and make it projct-wide and not local for debugger
 - added new 'info sse' command for debugger
 - extend 'modebp' command to break on any mode change
 - remove unimplemened 'info program' function, it is always printed fixed text
 - move debugger help to parser, cleanup and simplify it

08c15c67c0 Don't know how much it helps ...

c92aba3776 Using back tracking in CVS I found the reason why CVS sources not compiled with configure --enable-debugger configuration (reported by Brendan).
Again it is andom change which cause to debugger not to compile ;(
This is definitelly GCC bug !
