3a0dff9b36 fixed Bochs compiled for 386 with FPU enabled 2015-06-10 20:36:46 +00:00
Stanislav Shwartsman
c43ea147bf ~1% emulation speedup by skipping pageWriteStamp check for stack writes. 
For now the optimization is supported only when no SMP is compiled in because it doesn't handle cross-modifying code.

The current stack page will cache also current pageWriteStamp for that page and could skip pageWriteStamp access if possible.
Any code fetch access missing trace cache will invalidate current stack page.
Code fetch accesses from another SMP threads should do the same to support SMP.

Next step:
 - support SMP
 - support pageWriteStamp access skipping for all other memory writes from all segments

f0d7379908 remove BxResolveModrm member in BxInstruction_c class and inline resolve functions into instruction handlers instead. helps to remove indirect branch mispredictions (suggested by Vtune). measured speedup on Win7-64 boot is 5%, on other guests it might vary between 1% and 5% 2015-05-16 20:29:49 +00:00
