404b8b1475 move end of trace indication to separate 'flags' field of bx_ia_opcode. this saves a lot of code duplication and simplifies the decode tables. also on the way found missing SVM opcodes that missed 'end of trace' mark 2013-09-21 18:58:01 +00:00

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

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.

b5c5082ff2 Completely remove b1() field from bxInstruction structure and resuse it for AVX instructions flags. 
the iaOpcode field has no masking anymore.

fixed bug during the code reorganization:
                        
+ XOP: Fixed instructions with operands order depending on VEX.W (fixed VEX.W read from instruction object)

62d0c8abf7 - Now you could disable x86-64 from .bochsrc so now it is possible to emulate 
32-bit CPU using Bochs binary compiled with x86-64 support.

The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.
