- Minor Changes/Cleanup
Super VU:
- Used the Linux SysMmapEx address for windows as well.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1308 96395faa-99c1-11dd-bbfe-3dabce05a288
- Implemented some bizarre behavior where conditional branches will read old VI-reg values if the previous instructions continuously read+write to the VI reg.
example from zerorec's comments:
SQI vi5++
SQI vi5++
IBNE vi4, vi5
vi5's value in the branch should be the value before all the SQI's...
more examples in iVUzerorec.cpp

- Non-functional change... just storing some IR info I'll need to use later.

- Tried a complex optimization with status flag updating.
Didn't seem to work out as well as I thought.
I need some benchmarks of mVU (w/o hacks) before this update and after this update to see how effective it is.
If its not much faster I might just revert the change (because I'm sure no-one is going to understand how it works this way).

- Fixed a bug from r1254. (Fixes weird circles on the logo of ffxii after selecting new-game)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1299 96395faa-99c1-11dd-bbfe-3dabce05a288
- Gave the rec a better IR (intermediate representation) implementation.
- Renamed microVU_Alloc to microVU_IR

- It took a while, but I managed to convert 100's of template functions to normal functions, reducing release link times by about ~50% again.
pcsx2 takes about ~2 mins to link on release build, which is a lot more tolerable than ~10 minutes from a few days ago...

Also prepared some code to add support for VU looping in MTGS mode, this will require a GS Spec update, so its commented out for now until i can sync an update with Gabest.

- Changed 'recPass' from a template param to a function param. Halves MSVC linking-time in release modes, but still slow (from ~10 minutes to ~5 minutes to link on my PC). I'll continue working on this later... the next change will probably reduce Release link-times to 1~2 minutes (or less than 1 minute for you guys with macho-pc's ;p).
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1287 96395faa-99c1-11dd-bbfe-3dabce05a288
- Added a 1-cycle xgkick delay, fixes SO3 graphic corruption and flickering.
Theres still VU stuff the game does that isn't implemented, but the game seems to run fine w/o the implementation (only tested the beginning though).
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1282 96395faa-99c1-11dd-bbfe-3dabce05a288
- Implemented the tri-ace gamefix.
Note: I've only tested SO3 so-far and it has some ugly graphical problems with mVU. SO3 does some evil VU stuff that it shouldn't be doing, but it does them anyways xD
I know the cause of the problems, so I just have to code the solutions sometime in the future...
P.S. SO3 looks really funny with the FlagHack1 speedhack! The characters turn into floating heads effectively turning the game into PacMan xD

microVU speedhacks are also available in the speedhacks dialog.
All the GUI stuff took me a few hours, so hopefully I didn't bug anything.
Note to users:
Please remember that microVU is a W.I.P. and will have bugs; but it also fixes some games Super VU has problems with. So have fun testing.

And there is even an explanation.
The tfx functions calculate At * Af >> 7, which means modulating by 0x80 should return At as the result.
With the evil floating point pixel shader however 0x80 translates to 128/255 (0.502), not exactly 0.5, modulation as At' * Af' * 2 (' means 0 - 1.0 range) is not the same as with integers.
At' = Af' = 0.502
At' * Af' * 2 = 0.504
If the alpha test happens to be "not equal to 0x80", then abs(0.504 - 128/255) < 0.5/255 will just miss.
Solution is to re-scale those values to the integer range, do the calculations, and then back to float again, but in the end it just simplifies down to At' * Af' * 255/128, doh...
At * Af >> 7 => ((At' * 255) * (Af' * 255) / 128) / 255 => At' * Af' * 255/128
At' = Af' = 0.502
0.502 * 0.502 * 255/128 = 0.502 (w00t!)

- Increased mVU run cycles (Fixes Kloana 2's Inf Loop messages)
- Fixed some potential problems with the log code that would cause some games to crash.
- Minor Changes...
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1271 96395faa-99c1-11dd-bbfe-3dabce05a288
- Fixed a big bug with the help of sudonim and rama which greatly increases mVU's compatibility!
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1270 96395faa-99c1-11dd-bbfe-3dabce05a288
- Properly fixed problems from r1254, a lot of games should be fixed.
pcsx2/microVU:
- Added some debug code that runs sVU and mVU, and compares their results. If they differ, then the game is halted, and debug info is given. (this can be enabled in iVU1micro.cpp with the DEBUG_COMPARE2 macro)... the code is a bit messy, but it gets the job done for now.

Also semi-removed my gifsplit thing to resolve the tekken 5 menus Issue 209
Note: GT4 is still missing its logo, this is down to a really bizzare timing issue i cant pinpoint.
Removed redundant path3hack
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1257 96395faa-99c1-11dd-bbfe-3dabce05a288
- Implemented an idea by Jake to use a GPR as a reg-offset index to save a few bytes from reg-moves (only did it for VI regs, didn't have enough free GPR's to do it for VF regs)
- Fixed a minor problem with micro-program logs
