c81a91fd72 Moved integer registers, PC and flags_* variables into new cpu_state structure. Reduces recompiled code size slightly, small speedup (1-3%). 2016-04-20 21:39:41 +01:00

36bb949126 If recompiler block hash table points to wrong block, then walk tree to find correct block instead of recompiling. Speedups of 10-20% on games that were seeing hash aliasing, eg Quake III, System Shock 2, UltraHLE etc 2016-04-06 20:48:36 +01:00

38fb86cb95 stack32 is now always 0 or 1, to prevent failed comparisons in 386_dynarec.c.
Only clear an entry in codeblock_hash if it's pointing to the block actually being deleted.
Speeds up menus in Railroad Tycoon II significantly.
