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

03eac64013 Added decoding of new SSE4 instructions (recently published in Intel docs) 
At least CPUID detects them correctly
The code is never tested (still) ! (but should work fine)

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 ...
