9b30cad4c4 Just software changes: 
1. Separate interrupt function to 3 different functions (real_mode, long_mode, pmode)
2. Added PANIC messages for not implemented FAR CALL, FAR JUMP and FAR RET in long mode

1755589376 Separate pageWriteStamp from ICACHE. The pageWriteStamp has totally independant structure and could be used in future with icache structure. Also it could be significantly speeded up using BX_SMF analog constructions. 2005-04-10 19:42:48 +00:00

619942cf9a Enable SYSENTER/SYSEXIT together with x86-64 support, these instructions used by gentoo amd64 LiveCD image (at least it WRMSR to SYSENTER MSRs). 
SYSENTER/SYSEXIT is not recognized in long mode but it could be used i any other mode without problem

22098eefa2 Removed unused instruction (function) methods which were generated as a result of the initial implementation of AMD64 support. 2005-03-28 06:29:22 +00:00

831afe7c40 Removed unused instruction (function) prototypes which were generated as 
a result of the initial implementation of AMD64 support.  These appear
  to have been cut-n-paste vestiges.

e6cb602231 Moved macros for duplicate SSE/SSE2 functions from fetchdecode.h to 
cpu.h, and defined function prototypes for the case where bochs
  is compiled with a new #define (called StandAloneDecoder) is set.
  This allows for the decoder to be tested separately from bochs.

Kevin Lawton
4e03c4448c Added some comment tags so that a script can pull out relevant parts 
of the decoder to test it in standalone mode.  A few lines in cpu.h
  were re-arranged to make this easy, but no real lines of code were
  changed or generated.
Changed a few PANICs to INFOs after testing corresponding cases.
