ec1ff39a5f Splitted memory access methods for 32 and 64-bit code. 
The 64-bit code got >10% speedup, the 32-bit code also got about 2% because laddr cacluation optimization

d9984bb3a1 Eliminate BxResolve call from the heart of cpu loop and move into instructions that really require this calculation. Yes, it blows the code of EVERY CPU method but it has >15% speedup ! 2008-01-10 19:37:56 +00:00

8221fa6838 - Fixed zero upper 32-bit part of GPR in x86-64 mode 
- CMOV_GdEd should zero upper 32-bit part of GPR register even if the
    'cmov' condition was false !

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

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 ...
