Removed the doubled up timings on SIF DMA cycles (should have been done when it was spotted really)
Put in a fix for Scratchpad reads which cause a VTLB error.

- Fixed a very rare case, where both upper and lower instructions read and write to each others regs.
Example:
ADD.xyzw VF1, VF2, VF3
MOVE.xyzw VF2, VF1
- Forgot to commit iVU0micro.cpp on my last update...
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1319 96395faa-99c1-11dd-bbfe-3dabce05a288
- Implemented m-bit functionality. Fixes Crash Twinsanity and most-likely other games...
Note: If anyone has any games that have broken graphics when mVU prints "microVU0: M-bit set!" to console, then please notify me about it.

- Removed flaghack1 since it didn't do much over flaghack2 (except break games :p).
Flaghack2 is now renamed to "Status Flag Hack", and so-far we haven't found a single game it breaks, so compatibility is high.

- Second try at a status flag optimization. Still needs tweaking but too tired xD

- 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...

- Non-functional change... just storing some IR info I'll need to use later.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1303 96395faa-99c1-11dd-bbfe-3dabce05a288
- 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...
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1291 96395faa-99c1-11dd-bbfe-3dabce05a288
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.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1289 96395faa-99c1-11dd-bbfe-3dabce05a288
- 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!)
