In MacOS 11.2 mprotect can no longer change the access protection settings of
pages that were previously marked as executable to anything but PROT_NONE. This
commit works around this new restriction by bypassing the mprotect based write
protection and instead relying on the write protection provided by MAP_JIT.
Analytics:
- Incorporated fix to allow the full set of analytics that was recommended by
spotlightishere
BuildMacOSUniversalBinary:
- The x86_64 slice for a universal binary is now built for 10.12
- The universal binary build script now can be configured though command line
options instead of modifying the script itself.
- os.system calls were replaced with equivalent subprocess calls
- Formatting was reworked to be more PEP 8 compliant
- The script was refactored to make it more modular
- The com.apple.security.cs.disable-library-validation entitlement was removed
Memory Management:
- Changed the JITPageWrite*Execute*() functions to incorporate support for
nesting
Other:
- Fixed several small lint errors
- Fixed doc and formatting mistakes
- Several small refactors to make things clearer
This commit adds support for compiling Dolphin for ARM on MacOS so that it can
run natively on the M1 processors without running through Rosseta2 emulation
providing a 30-50% performance speedup and less hitches from Rosseta2.
It consists of several key changes:
- Adding support for W^X allocation(MAP_JIT) for the ARM JIT
- Adding the machine context and config info to identify the M1 processor
- Additions to the build system and docs to support building universal binaries
- Adding code signing entitlements to access the MAP_JIT functionality
- Updating the MoltenVK libvulkan.dylib to a newer version with M1 support
Shouldn't have any behaviour change for regular usage as both masks are 32MB
by default.
But fixes theoretical buffer overrun when memory size override is used.
The interpreter implementation of fctiwx was treating rounding
mode 0 as "round to nearest, ties towards zero", which is not
an actual IEEE-754 rounding mode. The IBM document mentioned
in a comment at the top of the function, on the other hand,
treats rounding mode 0 as "round to nearest, ties to even",
which makes more sense.
This fixes one of JMC's console-recorded F-Zero GX replays on
JitArm64. (JitArm64 uses an interpreter fallback for fctiwx.)
The GC/Wii GPU rasterizes in 2x2 pixel groups, so bounding box values
will be rounded to the extents of these groups, rather than the exact
pixel. To account for this, we'll round the top/left down to even and
the bottom/right up to odd. I have verified that the values resulting
from this change exactly match a real Wii.
Any file which includes scmrev.h must be rebuilt when scmrev.h
is regenerated. By not including scmrev.h from any file other
than Version.cpp, incremental builds become a little faster.
When trying to do a small optimization in 8a0f5ea, I failed to
take into account that WeakFlush and FlushOne update m_query_count.
Only D3D11 and OGL had this problem, not D3D12 and Vulkan.
Sorry, the fix I made to the empty string in a29660a was not
actually sufficient, as DolphinQt will call tr on the string
regardless of whether it's marked with _trans. The proper fix
is to use nullptr, which DolphinQt has a special check for.
Sending an empty string to the translation system will not
result in getting an empty string back, but rather a description
of the currently loaded translations file. So empty strings
should not be marked as translatable.
Also adding some i18n comments and rewording a string I thought
was hard to understand.
casting a value to a u32 when it's originally an int, and it's exposed as int to users,
could end up in cases where a negative number would result as a positive one.
This doesn't really affect the value range of the attachment enum,
still I think the code was wrong.
Heavily tested.
Settings.SECTION_INI_ANDROID and Settings.SECTION_BINDINGS
both have the value "Android", but we only want the former
to be marked as being handled by the new config system.
This change fixes a problem where controller settings were
not being properly saved to Dolphin.ini.
The STL has everything we need nowadays.
I have tried to not alter any behavior or semantics with this
change wherever possible. In particular, WriteLow and WriteHigh
in CommandProcessor retain the ability to accidentally undo
another thread's write to the upper half or lower half
respectively. If that should be fixed, it should be done in a
separate commit for clarity. One thing did change: The places
where we were using += on a volatile variable (not an atomic
operation) are now using fetch_add (actually an atomic operation).
Tested with single core and dual core on x86-64 and AArch64.
NumericSettings support a max, so let's use it.
It might not do much now, but the max and min values will be used to give visual feeback
in the UI in one of my upcoming input PRs
The control expression editor allows line breaks, but the serialization was
losing anything after the first line break (/r /n).
Instead of opting to encode them and decode them on serialization
(which I tried but was not safe, as it would lose /n written in the string by users),
I opted to replace them with a space.
and replacing it with a ":" prefix. Also remove white spaces and \n \t \r.
bugfix: fix EmulatedController::GetStateLock() not being aquired when reading the
expression reference
bugfix: MappingButton::UpdateIndicator() calling State(0) on outputs, breaking ongoing
rumbles if a game was running
Improvement: make expressions previews appear in Italic if they failed to parse correctly
Previously we set the texture coordinate to zero, now we set
the texture coordinate *index* to zero. This fixes the ripple
effect of the Mario painting in Luigi's Mansion.
This change should have no behavioral differences itself, but allows for changing the behavior of out of bounds tex coord indices more easily in the next commit. Without this change, returning tex0 for out of bounds cases and then applying the fixed-point logic would use the wrong tex dimension info (tex0 with I_TEXDIMS[1] or such), which is inaccurate.

Since the description updating is tied to the selection changing on the detail list, and the detail list is recreated on each object change, behavior was somewhat broken. Clearing the list changed the current row to zero, but nothing else (particularly m_object_data_offsets) had been updated, so the description was not necessarily correct (this is easier to observe now since the vertex data is at the end, so it's easier to get different lengths of register updates). Furthermore, subsequent clears did not update the current row since there was no visible selection, so it only changed the description once. The current row is now always set to zero, which forces an update (and also scrolls the list back to the top). The presence of FRAME_ROLE and OBJECT_ROLE are also checked so that the description is cleared if no object is selected.
- Only one search result is generated per command/line, even if there are multiple matches in that line.
- Pressing enter on the edit field begins a search, just like clicking the begin button.
- The next and previous buttons are disabled until a search is begun.
- The search results are cleared when changing objects or frames.
- The previous button once again works (a regression from the previous commit), and the register updates and graphics data for the correct object are searched.
- currentRow() never returns -1, so checking that is unnecessary (and misleading).
- The 'Invalid search parameters (no object selected)' previously never showed up before because FRAME_ROLE is present if and only if OBJECT_ROLE is present.
This way, it can be focused with the render window behind it, instead of having the main window show up and cover the render window. This is useful for adjusting the object range, among other things.
If the number of objects varied, this would result in either missing objects on some frames, or too many objects on some frames; the latter case could cause crashes. Since it used the current frame to get the count, if the FIFO is started before the FIFO analyzer is opened, then the current frame is effectively random, making it hard to reproduce consistently.
This issue has existed since the FIFO analyzer was implemented for Qt.
The 'zero frames in the range' check can be removed because now there is always at least 1 frame; of course that might be the same frame over and over again, but that's still useful for e.g. Free Look (and the 1 frame repeating effect already occurred when frame count was exclusive).
A single object can be selected instead of 2 (it was already inclusive internally), and the maximum value is the highest number of objects in any frame (minus 1) to reduce jank when multiple frames are being played back.
Now that this is only called when playback actually starts (and not on unpausing), this change makes the experience a bit better (no more missing objects from not having reset the from object after changing FIFOs).
It is no longer relevant for the current set of loaders after 7030542546. If it becomes relevant again, a static function named IsUsable or IsCompatibleWithCurrentMachine or something would be a better approach.
By taking advantage of three-operand IMUL, we can eliminate a MOV
instruction. This is a small code size win. However, due to IMUL sign
extending the immediate value to 64 bits, we can only apply this when
the magic number's most significant bit is zero.
To ensure this can actually happen, we also minimize the magic number by
checking for trailing zeroes.
Example (Unsigned division by 18)
Before:
41 BE E4 38 8E E3 mov r14d,0E38E38E4h
4D 0F AF F5 imul r14,r13
49 C1 EE 24 shr r14,24h
After:
4D 69 F5 39 8E E3 38 imul r14,r13,38E38E39h
49 C1 EE 22 shr r14,22h
This isn't entirely necessary, as they are interpreted as barewords expressions,
but it's still nicer to have by default. And my upcoming input changes will
always put `` around single letter inputs.
-Add pause state to FPSCounter.
-Add ability to have more than one "OnStateChanged" callback in core.
-Add GetActualEmulationSpeed() to Core. Returns 1 by default. It's used by my input PRs.
The SaveToSYSCONF call in BootManager.cpp was unintentionally

Verifying a Wii game creates an instance of IOS, and Dolphin
can't handle more than one instance of IOS at the same time.
Properly supporting it is probably more effort than it's worth.

Avoids the need to copy the *.mo files manually *and* more importantly
this ensures that the mo files are always recreated if the build
output directory is cleared.
Update references was failing to update the references, causing input to stay nullptr and crashing.
I fixed the case that triggered that, though also added checks against nullptrs for safety.

I think the AArch64 JIT has come far enough that it doesn't have to
be called experimental anymore.
I'm also labeling the x86-64 JIT as x86-64 for consistence with the
AArch64 JIT. This will especially be helpful if we start supporting
AArch64 on macOS, as AArch64 macOS can run both the x86-64 JIT and
the AArch64 JIT depending on whether you enable Rosetta 2.
