/fp:fast was introducing FP precision problems, and mixing it with some
/fp:precise code caused strange game behaviors, DSI exceptions and freezes.
This commit should fix most of the issues introduced by 3.0-73 (r95517a97).
Thanks to hatarumoroboshi@hotmail.com for tracking a lot of these Win32 bugs.
Fixes issue 4906.
Fixes issue 5138.
Probably fixes (not tested) issue 5067.
to marcosvitali.
Added an external exception check when the CPU writes to the FIFO. This allows
the CPU time to service FIFO overflows. Fixes random hangs caused by FIFO
overflows and desyncs like in "The Last Story" and "Battalion Wars 2". Thanks
to marcosvitali for the research.
Added some code to unlink invalidated blocks so that the recompiled block can be
linked (speed-up).
This release still fixed the hangs produced by fifo overflow without sacrifice
performance. For example you can test Tutorial moves at the beginning of The last history now
is fluid 30/60.
Fixed possibles random hangs in DC mode.
Fixed hangs in DC mode in (Simpsons, Monkey Island, Pokemon XD, etc)
Implemented accurate management of Pixel Engine Interrupts. Now the GPU loop
is stopped when a PE Interrupt needs to be managed and resumed when Pixel Engine
finish.
Fixed Metroid Prime 3 and 2 desync. And other games with desync because of
FIFO Reset. That happens because FIFO_RW_DISTANCE_HI must be written first, for checking
fifo.CPReadWriteDistance == 0, so some fifo resets was not managed in the right
way.
Fixed Super Monkey Ball in some cases when the game write the
WriteReadDistance need to be safe like the SafeCPRead.
Improved the CheckException for the GatherPipe writes in JIT, now only the
External Exceptions are processed.
Fixed definitely Pokemon XD in dual core mode. This game is doing something
not allowed. It attach to CPU the same fifo attached to the GPU in multibuffer
mode. I added a check to prevent overwrite the GPU FIFO with the CPU FIFO. If
the game do that on breakpoint the solution can fail.
Fixed ReadWriteDistance calc when CPRead > CPWrite.
Added Token and Finish cause to GP Jit checking.
Additional cleanup in CommandProcessor.

Commit 9ddb67d4a9 seems to have
introduced a segfault on Mac. The issue is that it this change casts
wxConvCurrent (which is a wxMBConvLibc) to a wxCSConv. This is an
unsafe cast because wxCSConv has member variables, but wxMBConvLibc
does not.
In LogWindow.cpp, the constructor for m_SJISConv is dereferencing one
of those member variables, which is a dereference of uninitialized
memory!
This CL reverts to the older (non-crashing) constructor, but keeps the
behavior the same.
Specifically:
- Look for clang and clang++ in the new (Xcode 4.3) location first,
then the old (Xcode 4.2) location.
- Look for sysroot in the new (Xcode 4.3) location first, then the old
(Xcode 4.2) location.
Fixed the JIT cache, invalidating one instruction length at a time.
Fixed a bug where the JIT cache did not get invalidated when stepping.
Disabled fused instructions in the debugger.
Sorry guys but I needed to disable stfs so that Pokepark 2 would not freeze(?). Feel free to put some effort in to finding out why, I do not understand Jit sorry.
We Didn't Check 0x0008000 in PowerPC::ppcState.msr this was killing the performance, this also fix a hang when this check is performed.
SMG for example.
Deleted the HiWatermark condition from GPFifo.
Please test games affected in this Revision 9e649ce798, and games affected in this Revision b0f75f17ae.
I do not want to excite the game players of 'The Las Story', but Could test again the random hangs with this rev?
Thanks
This fix is not related with the previous commits, but the previous commits help me to see that because in the new scenery SMB was hanging. May be in the past also doesn't boot some times because of that.
Please Test FZero boot also. Thanks.
The external exceptions in dolphin are checking frequently but is different to real HW, so sometime the game is in a loop checking GPU STATUS, the exceptions doesn't checked, and the game hang.\
For solve this I need a trick: still waiting for the exception handler be linked but if CommandProcecsor is reading the GPStatus, resume this.
This fixed "TimeSplitters: Future Perfect" broken in the Revision c2e6fdf09f and surely others games.
That happens because FIFO_RW_DISTANCE_HI must be written first, for checking fifo.CPReadWriteDistance == 0, so some fifo resets was not managed in the right way.
I didn't test Metroid 2 desync reported in Issue 4336 but I think is the same.
About the flickering in MP2, I don't know for my is not related or yes, but you can test anyway.
Fixed Issue 3902
Well now the FIFO is 99.99% finished :)
- I've fixed hangs in DC mode in (Simpsons, Monkey Island, Pokemon XD, etc)
- I've implemented accurate manage of Pixel Engine Interrupts, now the GPU loop is stopped when a PE Interrupt needs to be managed and resume when Pixel Engine finish,
I think now, the Fifo in DC mode is more accurate than SC mode. :)
Time to close the big fifo Issue 3694 (snif), please if you have a possible fifo issue report this like a game issue.
I was working with Skid_AU together, especially thanks for him.
Test a lot all games, and compare the performance with the master maybe this accuracy has a cost (not a lot).
I think now the fifo is very stable, overflow fixed, random hang fixed, if you have a game with a hang with this rev and not in master please report this.
