75f9316c11 x86-32 recompiler compiles FPU instructions using direct access to register stack when top-of-stack is static. Minor speedup. 2016-09-11 15:38:05 +01:00

42237ac1f8 Recompiler now only recompiles a block after seeing it twice. Improves performance on stuff that uses self modifying code - eg Doom, Duke Nukem 3D, Windows 95 idle 2016-07-31 12:33:37 +01:00

14df80109b Added recompiler block tree to x86-64 recompiler. Fixed return value in codeblock_tree_find() that could cause GCC to generate bad code. 2016-04-08 20:49:03 +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

673d785743 Writing to a memory page with code present only causes code block flushes if the data changes, or if a block is currently being recompiled. 2016-02-03 21:09:05 +00:00
