Removes Ignore Key(hasn't functioned since LilyPad 0.9.9 (PCSX2 0.9.6)),
and "Send escape on window close" hack (unnecessary for PCSX2 and caused
issues with other emulators).
This new option on the pad tabs disables an input so it will be ignored
when trying to bind another input. This is helpful when binding controls
for a device with an input that's difficult to center like an
accelerator, or just always active like a faulty button or analog stick.
Avoid reading past the end of the disk.
Avoid waiting when there are prefetches remaining.
Fix the maths so that the first prefetch after a request attempts to
read the next block of sectors and not the block of sectors that was
just read (which will just be skipped anyway because the data has just
been cached).
Avoid potential prefetch after disk is swapped (though disc swap doesn't
work properly if you just eject and insert a different disk).
Stop prefetching on disk read failure (Suikoden hits this case - 2048
byte reads are requested, but only 2352 byte reads will succeed).
Also reduce the read retry count to 2.
16B alignment is now useless for nVifBlock (no more SSE)
However update the alignment of bucket to 64B. It will reduce cache miss
probability in the find loop
It avoids memory stalls and greatly reduces the overhead of the dVifUnpack function
Here a vtune summary of this branch (done on SotC init)
dVifUnpack<1> was 14.5% of effective VU thread time
dVifUnpack<1> is now 3.8% of effective VU thread time
I hope it will translate to better fps
Delete() deletes the menu item but keeps the sub menu. Remove() doesn't
delete the menu item.
Also use AppendSubMenu - using Append on a submenu is deprecated.
It allow to compare only 8B in the lookup so SSE could be replaced with general instruction
As a bonus, it allow to compute the hash key with a mov rather than modulo (which was an 'and')
Inline the execution part
Add a num parameter to dVifsetVUptr
Use a local variable for the nVifBlock instead of a global struct state
The goal is to ease future update of the nVifBlock struct
Previous implementation saved the both the chain pointer and the chain size
Rational: size is useful to add new element and to detect the end of the chain
Vif cache is rarely miss. So 'add' is barely called and the end of a chain is
barely reached.
New implementation will add a null cell at the end of the chain. As a
cell contains a x86 pointer, if is null you could conclude that you
reach the end of the chain.
The 'add' function will traverse the chain to get the current size. It is
a cold path besides the chain is often short (< 4).
The 'find' function only need to check the startPtr bytes to detect the end
of the loop.
Note: SizeChain was replaced with a std::array
Safety:
* check remaining space before compilation
* clear hash if recompiler is reset
Perf:
* don't research the hash after a miss
* reduce branching in Unpack/ExecuteUnpack
Note: a potential speed optimization for dVifsetVUptr
Precompute the length and store in the cache. However it need 2B on the
nVifBlock struct. Maybe we can compact cl/wl. Or merge aligned with upkType
(if some bits are useless)
I misses some early return in my first tentative. Now VTune shows me
properly the time in VU recompiler.
Note: It seem some block overlap (likely due to the branching mess). But it is still way better than no data
GS_Packet constructor calls memset which is quite slow and useless as data is overwritten
Vtune overhead of Gif_Unit::Execute goes from 5.8% to 3.0% (EE thread)
Several PSX titles lack a backslash in the elf path, which made the disc
serial contain 'cdrom:', this caused savestate issues in those ganes.

Use a reinterpret_cast instead of casting the function pointer address
to a void** and dereferencing it.
Also remove an unnecessary (void) and avoid including stdafx.h.
Don't adjust 'image' and just use an additional offset.
'success' was kinda unnecessary when true or false could just be
directly returned.
Move 'compression' clamping out to GSPng::Save instead.
And throw in a whole bunch of const for good measure.
wchar_t is 16-bits on Windows, which can't actually properly fit all
Unicode characters.
Use the wx3.0.x wxTextWrapper approach of using iterators that increment
by actual characters to fix the issue, and also switch to using the
std::string style functions in wxString.
Previously the boot menu items always displayed "Boot CDVD" regardless of the current source medium, this behavior has been fixed to properly adjust the text when source medium is changed. Now it'll display Boot CDVD/ISO/BIOS with respect to the current source medium.
v2: Some instances of "Iso" have been changed to "ISO" for consistency.
v3: Remove the unnecessary "Reboot" on menu item labels, saves some string translations.
v4: Add a new shortcut key for the primary boot menu item.
There is already a dedicated bind event to handle the gray out of the menu item, so let's just gray it out initially and let the bind event handler do it's thing.
The previous behavior would only gray out the menu item when all the plugins are in a non-active state which didn't seem ideal as the plugins were shutdown only when closing PCSX2 (or) switching plugins.
Adds a device select option that hides bindings and disables binding new
inputs from all non-selected devices on the bindings list. This also
avoids input conflict issues when one controller is recognized as
several devices through different APIs.
Updates the UI by reducing the height of the plugin window. This has
been achieved by removing some buttons below the diagnostics and
bindings list and incorporating those functions into the
lists(accessible by right-clicking in the list). The binding
configurations on the Pad tabs have been moved to a separate page, like
the Forcefeedback bindings, to separate the configuration from the
bindings.
Adds a skip deadzone option to the Pad tabs.
With the normal deadzone, if the control input value is below the
deadzone threshold, the input is ignored.
However, some controllers also benefit from shortening the input range
by skipping a deadzone.
JMMT uses a bigger display height on NTSC progressive scan mode, which is not really unusual hence adjust the saturation hack to only take effect on interlaced NTSC mode.
However, the whole double screen issue on FMV still exists. As a bit of information, this game has the second output disabled but seems to have some valid data inside of it, maybe the second output data is leaked into the first one? most likely a bug in the frambuffer data management rather than a CRTC issue (needs to be investigated)
in the top-level source directory. The build folder should NOT be
transferred between computers when PGO is used, though I don't
see why anyone would be doing so anyway.
Also adds support for PGO and LTO to the build.sh script.
