- 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
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.
With this coding style each instruction could be implemented separatelly even not together with current Bochs FPU emulator.
Step-by-step I am going to transfer all FPU instructions from current Bochs FPU emulator to new style and remove an old bugged emulator.
Anyway, now I could implement all currently missed FPU instructions without hacking wm-fpu-emu.
PNI could be enabled by setting BX_SUPPORT_PNI in config.h
After the feature will be fully validation I'll also add configure option.
The implemntation is ~complete. I've missed only three FPU new opcodes of FUSTTP instruction and MONITOR/WAIT instructions.
Enjoy ! ;)
