405fcfd75d Reorganize 3-byte opcode tables - bigger tables but easier to maintain them 2008-02-29 03:02:03 +00:00
Stanislav Shwartsman
cdcd7522aa Added RIP to the GPR register file as lst register
This allowed to optimize (read - remove) two more BxResolve methods in 64-bit mode
+ Some white space cleanup

fb0ce45d28 Unpack more fields in bxInstruction_c -> this increase bxInstruction size by 4 bytes but I have no way but do it if want to support SSE5 dest override later 2008-02-04 21:28:53 +00:00

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

05c7a1e61b Fixed problem with trace cache enabled
String instructions might confise trace cache by finishing instruction execution method without actually completing an instruction (and advancing eip)

506dc3d963 Optimize 64-bit fetchdecode prefix handling
Deparecated set_FLAG() method, setB_FLAG() method was used everywhere
Rename setB_FLAG to set_FLAG, so set_FLAG() will must receive 0/1 inly

db02731cbf Replace BxAnother attribute in fetchdecode by table lookup like it is done in disasm. This is done in preparation to feature huge fetchdecode change - all fethdecode tables will be duplicated and made separatate table for ModC0 and others.
So ALL instructions will emjoy SplitMod11b automatically (if they want).
After splitting ALL instruction I hope to get 20% speedup at least.
