b78e93c9e3 optimize handling of allowed_to_run_FPU_MMX instructios common block 
now checked at decode and not at every instruction
simpler code and also 1% faster winXP boot time as bonus
other x87 and mmx heavy guests may benefit even more

1bf18b8aae ! CPUID: Added TigerLake CPU definition (features CET and CLWB support) 
- CPU code refactor, remove uses of bx_bool datatype and use C++ classic bool instead.
  This enable better compiler optimizations and reduce binary size

7a34f00f99 extracted fetchdecode into separated folder under cpu and also out of BX_CPU_C class into stand-alone module. Next step: wrap it up nicely and define clear interace to CPU model to minimize dependencies. Ideally I need fetchdecode to not include CPU at all 2016-06-12 21:23:48 +00:00
