058c0e05fb - removed wx debugger dialogs (enhanced gui debugger now almost stable with wx) 2013-02-16 12:22:13 +00:00

97de484efb use enhanced gui debugger instead of classic wx debugger if BX_DEBUGGER_GUI == 1 
The Windows version looks almost stable, but the GTK version fails in some cases.
That's why the classic wx debugger is still available if BX_DEBUGGER_GUI is set to 0.
- added function close_debug_dialog() to handle the simulation stop case in wx
- disable all the wx debugger related code if BX_DEBUGGER_GUI is set to 1
- added enhanced debugger specific init code similar to the code in sdl.cc
- include debugger related resources on Windows
- TODO: make the GTK / wxGTK case stable and remove the wx debugger

744001e35e Implemented VMX APIC Registers Virtualization and VMX Virtual Interrupt Delivery emulation 
Bugfix: VMX: VmEntry should do TPR Virtualization (TPR Shadow + APIC Access Virtualization case is affected) and even could possibly cause TPR Threshold VMEXIT

2638c1136a Add RDRAND/RDSEED instructions support (+ disasm) 
Of course no true random numbers will be generated - use standard "C" rand() function as stub.
In future it will be possible to improve (using another random generator) or even use real rdrand/rdseed intrinsics

2ca0c6c677 Move INTR, Local APIC INTR and SVN VINTR into new event interface (hardest part)

c41cbe6d56 Link traces over taken branch optimization which makes handlers chaining even more efficient. 
I observed 5% speedup in all disk images over 2.6pre1.
The change is safe (passed all regressions) and I will be glad to make it into Bochs 2.6!

cc694377b9 Standartization of Bochs instruction handlers. 
Bochs instruction emulation handlers won't refer to direct fields of instructions like MODRM.NNN or MODRM.RM anymore.
Use generic source/destination indications like SRC1, SRC2 and DST.
All handlers are modified to support new notation. In addition fetchDecode module was modified to assign sources to instructions properly.

Immediate benefits:
- Removal of several duplicated handlers (FMA3 duplicated with FMA4 is a trivial example)
- Simpler to understand fetch-decode code

Future benefits:
- Integration of disassembler into Bochs CPU module, ability to disasm bx_instruction_c instance (planned)

Huge patch. Almost all source files wre modified.
