ix86 Fixed bugs in BTS instruction emitters, and working on fixing bugs in BTS memory protection. 2009-04-29 20:55:13 +00:00
ix86-32 Removed VU-Skip [helps simplify the frameskipper logic] -- Use the VU Cycle Stealer hack instead for better, faster, more stable speedups of the VU1 unit. 2009-05-02 09:04:47 +00:00
BaseblockEx.cpp Implemented another block lookup method. 2009-04-05 14:19:13 +00:00
BaseblockEx.h Reverted BTS due to unexpected complications, but retained a minor optimization we developed during the BTS experiment. :) 2009-04-30 01:16:25 +00:00
Makefile.am Linux: Some work on the plugin code. 2009-03-06 07:20:16 +00:00
README Should be the last of the trunk, gotta finish the branches/tags, but thats the main bulk transferred. 2009-02-06 20:04:37 +00:00
aMicroVU.S Remove lots of evil %'s. 2009-03-05 21:35:26 +00:00
aR3000A.S Rewrite immediate jumps from the block manager instead of having dispatchers to do this at execution time. 2009-03-14 16:30:35 +00:00
aVUzerorec.S Remove lots of evil %'s. 2009-03-05 21:35:26 +00:00
aVif.S Optimized and split up the unpack call a bit so less checks are being run, should bring an overall speed increase. Also got rid of some duplicate pointer rubbish which was all over the place. 2009-04-11 17:45:14 +00:00
aVif.asm Should be the last of the trunk, gotta finish the branches/tags, but thats the main bulk transferred. 2009-02-06 20:04:37 +00:00
fast_routines.S Linux: Fix Final Fantasy XII. (memcmp_mmx appeared to be freezing MMX and not thawing it, and it didn't freeze it in Windows.) Comment out some unused code. Remove some code I commented earlier. And consolidate some of the calls to FreezeXMMRegs/FreezeMMXRegs. 2009-03-13 01:05:43 +00:00
fast_routines.cpp Fixed a bug in memcpy_fast that caused memory corruption on blocks not aligned to 32-bits in length (this might fix the linux memcpy fast problem too). 2009-03-09 21:52:33 +00:00
iCOP0.cpp Looks like the new PCR/TIMR code wasn't called correctly in recMFC0. 2009-03-15 12:24:24 +00:00
iCOP0.h Updated the Copyright to reflect the passing of another year. :) 2009-02-15 23:23:46 +00:00
iCOP2.cpp Added the second part of emitter macro functionality, by making the emitter instance configurable. We can't actually use it yet tho, since everything shares iCore, and thus everything needs to share the same emitter instance (for now!). 2009-03-01 20:44:48 +00:00
iCore.cpp Started consolidating the various Dump routines, most of which are broken, into one file. 2009-04-22 13:25:26 +00:00
iCore.h Started consolidating the various Dump routines, most of which are broken, into one file. 2009-04-22 13:25:26 +00:00

iFPU.h pcsx2: 2009-04-04 06:20:48 +00:00
iFPUd.cpp Cleaned a few things up, and moved a few things around. 2009-04-15 01:25:11 +00:00
iMMI.cpp Moved a few things around. Redid some of the work I did earlier on Hw with the non-obsolete version of the code. Changed some code not to use defines... 2009-04-24 02:28:14 +00:00
iMMI.h Updated the Copyright to reflect the passing of another year. :) 2009-02-15 23:23:46 +00:00
iPsxMem.cpp Some header work, get rid of some dead code, and rename PsxCommon.h. 2009-03-13 04:49:23 +00:00
iR3000A.cpp Finished the emitter, complete with code cleanups! :) (added last few SSE instructions, and inserted placebos for some future additions to the x86 portion, regarding xchg/xadd/etc). 2009-04-23 12:39:59 +00:00
iR3000A.h Reverted the emitter back to a c/cpp form from inl files (probably wasn't necessary, but I don't like having code in header/inl files when I can help it). Also: 2009-04-07 21:54:50 +00:00
iR3000Atables.cpp Switched the emitter over to using Thread-Local storage (TLS), which removes all the templates and brings us back to a more traditional-looking, macro-free, and intellisense-friendly implementation. Plus it's a lot less prone to errors and will make debugging easier down the road. (next commit will rename the files back to .cpp and get them out of the header includes) 2009-04-07 16:54:02 +00:00
iR5900.h Moved a few things around. Redid some of the work I did earlier on Hw with the non-obsolete version of the code. Changed some code not to use defines... 2009-04-24 02:28:14 +00:00

iVU1micro.cpp microVU: 2009-04-25 06:39:16 +00:00
iVUmicro.cpp Disabled a VU recompiler option that caused some SPS in Ratchet and Clank and didn't actually affect speed. 2009-04-08 18:19:48 +00:00
iVUmicro.h Fixed a bug in the savestate system that caused memcards to eject when they shouldn't have (had uint instead of u64 >_<). 2009-02-27 01:43:43 +00:00
iVUmicroLower.cpp Emitter: Changed a lot of 'i's into 'x's, because... 2009-04-20 03:10:05 +00:00
iVUmicroUpper.cpp Added CMOV to the emitter, renamed x86Struct stuff to iStruct, renamed XMMREGS / X86REGS / MMXREGS defines to iRegCnt_XMM / iRegCnt_GPR / iRegCnt_MMX, and undid a couple u32 optimizations which could have caused unexpected behavior in the future, if we ever decided to employ some particularly obscure case of self-modifying code. 2009-04-15 21:00:32 +00:00
iVUops.h Updated the Copyright to reflect the passing of another year. :) 2009-02-15 23:23:46 +00:00

PCSX2 x86 Recompilers - zerofrog(@gmail.com)
    
There are two types of x86 recompilers: x86-32 and x86-64. The code that both of them share is in the x86/ directory. Code for x86-32 is in the ix86-32/ and same goes for x86-64. The ix86/ dirctory contains the low level translation of x86 instructions to actual code, it is written to be used for both architectures. There are a lot of places where it was hard to separate 32bit from 64bit recompilers, so a lot of functions are surrounded by "#if(n)def __x86_64__" statements.

It would be simple if the story ended here, but hte x86 recompilers use a lot of low level assembly routines, meaning that assembly has to be compiled for both windows x32/x64 versions and linux x32/x64 versions.

For windows, the masm assembler is used (*.asm files)
For linux, gcc is used (*.S files)

Both assemblers use very different syntax, also some routines in x86-64 differ a lot from their 32bit counterparts. Therefore, you might see the same function implemented up to 4 times in assembly.

(no, it's not fun maintaining 4 versions of the same thing... and it might be easier to use nasm, but that probably has its own unforseeable problems)
