Esme 8ba735c208 Include arm_neon.h in mingw targeting ARM Windows.
The llvm-mingw project includes cross-compilers targeting ARM: https://github.com/mstorsjo/llvm-mingw/releases

Currently, compilation fails with this configuration, because neon features are used as long as __ARM_NEON is defined, but arm_neon.h was not included.

Cameron Gutman dfa64eadd3 KMSDRM: Add hint to enable the backend without DRM master
In some cases, it can be useful to have the KMSDRM backend even if it cannot
be used for rendering. An app may want to use SDL for input processing while
using another rendering API (such as an MMAL overlay on Raspberry Pi) or
using its own code to render to DRM overlays that SDL doesn't support.

This also moves the check for DRM master to an earlier point where we can fail
initialization of the backend, rather than allowing the backend to initialize
then failing the creation of a window later.

Misa dfe219ec71 Add all missing "is characteristic" stdlib functions
SDL has been missing a bunch of these 'isX' functions for some time,
where X is some characteristic of a given character.

This commit adds the rest of them to the SDL stdlib, so now we have:
- SDL_isalpha()
- SDL_isalnum()
- SDL_isblank()
- SDL_iscntrl()
- SDL_isxdigit()
- SDL_ispunct()
- SDL_isprint()
- SDL_isgraph()

Jay Petacat f443a6fc7a Fix format string warnings for width-based integers
The DJGPP compiler emits many warnings for conflicts between print
format specifiers and argument types. To fix the warnings, I added
`SDL_PRIx32` macros for use with `Sint32` and `Uint32` types. The macros
alias those found in <inttypes.h> or fallback to a reasonable default.

As an alternative, print arguments could be cast to plain old integers.
I opted slightly for the current solution as it felt more technically correct,
despite making the format strings more verbose.

Sam Lantinga ef52560a24 Fixed bug 5539 - Clang 11 fails to compile a CMake build with conflicting types for _m_prefetchw
vladius

In SDL_cpuinfo.h it seems like <intrin.h> is not included when __clang__ is defined, as the comment in the file explicitly reads:
"Many of the intrinsics SDL uses are not implemented by clang with Visual Studio"

However, the SDL_endian.h header does include <intrin.h> without any precautions like:
>#ifdef _MSC_VER
>#include <intrin.h>
>#endif

Maybe it should be changed to something like:
>#ifdef _MSC_VER
>#ifndef __clang__
>#include <intrin.h>
>#endif
>#endif

Cameron Gutman 79cd8cab08 Add default handler for Alt+Tab while keyboard grab is enabled
By default, we will minimize the window when we receive Alt+Tab with a
full-screen keyboard grabbed window to allow the user to escape the
full-screen application.

Some applications like remote desktop clients may want to handle Alt+Tab
themselves, so provide an opt-out via SDL_HINT_ALLOW_ALT_TAB_WHILE_GRABBED=0.

This adds SDL_SetWindowKeyboardGrab(), SDL_GetWindowKeyboardGrab(),
SDL_SetWindowMouseGrab(), SDL_GetWindowMouseGrab(), and new
SDL_WINDOW_KEYBOARD_GRABBED flag. It also updates the test harness to exercise
this functionality and makes a minor fix to X11 that I missed in
https://hg.libsdl.org/SDL/rev/02a2d609369b

To fit in with this new support, SDL_WINDOW_INPUT_CAPTURE has been renamed to
SDL_WINDOW_MOUSE_CAPTURE with the old name remaining as an alias for backwards
compatibility with older code.

Sam Lantinga ac72a2ba8e Fixed bug 5493 - Hint to let the user opt out of having Switch controllers' Home button lit when opened
jibb

New hint to let the user opt out of having Switch controllers' Home button lit when opened.

This is more consistent with the Switch itself (which doesn't light the button normally) and may be preferred by users who may disconnect their controller without letting the application close it.

I think this warrants a Switch-specific hint because the default behaviour is unusual (inconsistent with using a Switch controller on a Switch itself or with some other programs on PC), and because of that it's distinct from other lights (the player number on Switch controllers and the player colour on PlayStation controllers).

Cameron Gutman 6e97170e96 Use PS4 rumble hint as the default for the PS5 rumble hint
Existing SDL applications may not know about the need to set a specific
hint to enable rumble on PS5 controllers, even though they may already
set the equivalent SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE hint for PS4
controller rumble support.

Rather than requiring those developers update their apps, let's use the
SDL_HINT_JOYSTICK_HIDAPI_PS4_RUMBLE value as an indication of the behavior
they are expected for all PlayStation controllers.

Sam Lantinga 6a342954e8 Fixed bug 5451 - Can't create EGLSurface in Wayland from SDLWindow (no EGLNativeWindow pointer)
sashikknox

In some cases, need create EGLWindow with SDLWindow. In X11 i can get pointer to NativeWindow from **struct SDL_SysWMinfo wmInfo**
```C++
struct SDL_SysWMinfo wmInfo;
SDL_GetWindowWMInfo(ptSDLWindow, &wmInfo)
#if defined(__unix__) && defined(SDL_VIDEO_DRIVER_X11)
nativeWindow=(EGLNativeWindowType)wmInfo.info.x11.window;
nativeDisplay=(EGLNativeDisplayType)wmInfo.info.x11.display;
#endif
```
than i can create EGLSurface
```
eglCreateWindowSurface(nativeDisplay, EGL_CONFIG, nativeWindow, SURFACE_ATTRIBUTES);
```
in Wayland i can do it with same way, just need pointer to **EGLWindow**, we already have pointer to **wl_display** from **SDL_sysWMInfo**, need add to **wl** struct in SDL_SysWMInfo another pointer to **struct wl_egl_window *egl_window;**. And in wayland backend, in function **Wayland_GetWindowWMInfo** return pointer to **egl_window** from **SDL_WindowData**
Now i use patched statically built SDL2 in port of Quake 2 GLES2 for SailfishOS (it use QtWayland):
link to SDL2 commit and changed string for patch:
- 6858a618cd
- b1e29e87b9/SDL2/src/video/wayland/SDL_waylandwindow.c (L463)

link to use in Quake2 port:
1. here i get pointer to EGLNativeWindowType:  6d94fedb1b/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c (L319)
2. then use it for create EGLSurface: 6d94fedb1b/Engine/Sources/Compatibility/OpenGLES/EGLWrapper.c (L391)

wahil1976

This patch adds a written-from-scratch WSCONS driver for OpenBSD. It does not have hardcoded keymaps, and it features mouse support when wsmux is available.

For this to work, it needs access to the /dev/wskbd* devices which are not available to non-root users by default. Access to those can be granted by changing /etc/fbtab to give the logging user the ownership of those devices.

Vincent Hamm

Xcode11 and ios13 added support for metal simulator.
Here is a quick and dirty patch to enable it. Pretty early and only tested on a few samples for now. Required mostly to enable metal support on correct version of ios, generate simulator compatible shaders and enforce buffer alignments on simulator (same as osx).

This patch adds support to the GameController framework on macOS Big Sur and later, adding support for MFi controllers as well as rumble support for PS4 and Xbox One. There is some code to make sure that the IOKit joystick handler doesn't include two controllers at once.

While the GameController framework is present in earlier versions of macOS, there was no public, approved way of checking if a specific IOHIDDevice is a controller that GameController could handle. This was changed in Big Sur.

Sam Lantinga 07eae7d670 Fix process randomly getting killed when SDL_THREAD_PRIORITY_HIGH/TIME_CRITICAL is set
When we request realtime priority from rtkit, we have a rttime limit. If we exceed
that limit, the kernel will send SIGKILL to the process to terminate it.

This isn't something that most high priority processes will want, only processes
that selectively opt into SCHED_RR/FIFO through SDL_HINT_THREAD_PRIORITY_POLICY
should be subject to this level of scrutiny.

This change:
  * Switches non-apple posix OSs to use SCHED_OTHER instead of SCHED_RR
for SDL_THREAD_PRIORITY_HIGH/SDL_THREAD_PRIORITY_TIME_CRITICAL.
  * Fixes using a hardcoded RLIMIT_RTTIME, instead queries it from rtkit
  * Only sets RLIMIT_RTTIME for MakeRealtime rtkit requests
  * Adds a note regarding the possible SIGKILL with SDL_HINT_THREAD_PRIORITY_POLICY
  * Introduces SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL to allow apps to acquire realtime scheduling policies on Linux

Sam Lantinga 7c0986fba4 Fixed bug 4938 - Suggestion: rename SDL_PIXELFORMAT_BGR888 to SDL_PIXELFORMAT_XBGR8888
Ellie

I just tripped over this: stb_image when requesting 3 channels with 8-bit actually returns them as 3 bytes per pixel with no alignment, so basically 4 pixels are 12 bytes with no padding (0...2, 3...5, 6...8, and 9...11). This I would have naively expected to be called RGB888 or BGR888, since there is no "dead" unused byte as I would expect for something called e.g. RGBX8888.

However, SDL2's SDL_PIXELFORMAT_BGR888 uses 4 bytes, same as SDL_PIXELFORMAT_BGRX8888, even though the latter appears to be a longer storage format - which it isn't, internally. It's just swapped, in byte order X, B, G, R (instead of BGRX). So why isn't the macro name also swapped, as "XBGR888" instead of just "BGR888"?

I find the formats therefore named inconsistently, and unless there is a reason for this I suggest these changes:

1. deprecate SDL_PIXELFORMAT_BGR888 in favor of a new SDL_PIXELFORMAT_XBGR8888

and

2. deprecate SDL_PIXELFORMAT_RGB888 in favor of a new SDL_PIXELFORMAT_XRGB8888

1. Comment that SDL_SetThreadPriority will make any necessary system changes when applying priority.
2. Add a hint to override SDL's default behavior for scheduler policy.
3. Modify the pthreads SDL_SetThreadPriority so that instead of just using the current thread scheduler policy it will change it to a policy that should work best for the requested priority.
4. Add hint checks in SDL_SetThreadPriority so that #3 can be overridden if desired.
5. Modify the Linux SDL_SetThreadPriority so that in the case that policy, either by SDL defaults or from the hint, is a realtime policy it uses the realtime rtkit API.
6. Prior to calling rtkit on Linux make the necessary thread state changes that rtkit requires.  Currently this is done every time as it isn't expected that SDL_SetThreadPriority will be called repeatedly for a thread.

wengxt

Due to the new major fcitx version is coming close, the existing code need to be ported to use new Fcitx dbus interface.

The new dbus interface is supported by both fcitx 4 and 5, and has a good side effect, which is that it will work with flatpak for free. Also the patch remove the dependency on fcitx header. Instead, it just hardcodes a few enum value in the code so need to handle the different header for fcitx4 or 5.

Sam Lantinga 65ad45340d Improvement for bug 3446 - The haptic API does not allow to select the direction axes
meyraud705

I see how the documentation is confusing. I think that the choice of the axis is an implementation detail. The documentation should state the goal of this value, so I propose this wording:

    "Use this value to play an effect on the steering wheel axis. This provides
     better compatibility across platforms and devices as SDL will guess the
     correct axis."

Value could even be renamed 'SDL_HAPTIC_STEERING_AXIS'.

For Linux, sending an effect on the X axis with a Logitech wheel works. Others brands don't have driver for Linux as far as I know.

Sam Lantinga ed1d855865 Fixed bug 4299 - A recent change requires Core Bluetooth framework on iOS
Caleb Cornett

Just ran into this, and from my testing, whatever re-added the dependency is a _major_ regression. Not only is your app forced to link with CoreBluetooth, but iOS has apparently tightened up security and won't even let you _test_ your app unless it specifies the NSBluetoothAlwaysUsageDescription in an Info.plist. It doesn't even pop up an error message, it just straight up crashes.

Adding the permission isn't a good solution either, since I'd really, really rather not have my app request users' bluetooth to always be enabled, especially if the only apparent reason is for Steam Controller support.

Ryan C. Gordon a791689086 metal: Added some support interfaces to Apple's Metal API (thanks, Caleb!).
Caleb Cornett's comments:

"A few weeks ago, Alex added a partial Metal API to SDL2:

https://hg.libsdl.org/SDL/rev/22c8e7cd8d38

I noticed it was missing a few features that would help Metal become a
first-class citizen in SDL, so I went ahead and wrote them! Here are the new
APIs:

1. SDL_WINDOW_METAL flag for SDL_CreateWindow(). This allows the programmer
to specify that they intend to create a window for use with SDL_MetalView.
The flag is used to ensure correct usage of the API and to prevent
accidentally defaulting to OpenGL on iOS.

2. SDL_Metal_GetLayer(). This function takes a SDL_MetalView and returns a
pointer to the view's backing CAMetalLayer. This simplifies things
considerably, since in the current version of the SDL_Metal API the
programmer is required to bridge-cast a SDL_MetalView handle to an NSView or
UIView (depending on the platform) and then extract the layer from there.
SDL_Metal_GetLayer automatically handles all of that, making the operation
simple and cross-platform.

3. SDL_Metal_GetDrawableSize(). This function already exists in the current
SDL_Metal API (and is used behind-the-scenes for SDL_Vulkan_GetDrawableSize
on Apple platforms) but was not publicly exposed. My patch exposes this
function for public use. It works just like you'd expect.

Tested on macOS 10.14 and iOS 12.4."

Sam Lantinga 7379991778 Fixed bug 3446 - The haptic API does not allow to select the direction axes
Mathieu Laurendeau

Consider a device supporting effects on multiple axes.
There's currently no way to play effects against a single-axis direction.


A device supporting effects against X and Y may not allow to play effects with a two-axis direction coordinate, even if one of the coordinates is null.

My current (ugly) work around for this is to add a direction type SDL_HAPTIC_X_FORCE to play effects against a X-axis only direction (patch attached).

This issue impacted two GIMX users using the following wheels:
- Leo Bodnar SimSteering force feedback wheel
- Accuforce direct drive wheel

Playing constant/spring/damper effects against a X-axis direction worked well for the first wheel, but not for the second one.

A better strategy seems to play the effects against the first axis reported by the DirectInput enumeration.

This strategy also works with Logitech wheels (at least the DFGT).

It's been more than a year that I have the latest patch (playing effects against the first axis only) in the GIMX software. It's being used by thousands of people, mostly for adapting their FFB wheel to the PS4. I had no report that proves this strategy to be wrong.

Jimb Esser

Add new RawInput controller API, and improved correlation with XInput/WGI

Reorder joystick init so drivers can ask the others if they handle a device reliably
Do not poll disconnected XInput devices (major perf issue)
Fix various cases where incorrect correlation could happen
Simple mechanism for propagating unhandled Guide button presses even before guaranteed correlation
Correlate by axis motion as well as button presses
Fix failing to zero other trigger
Fix SDL_HINT_JOYSTICK_HIDAPI not working if set before calling SDL_Init()
Add missing device to device names
Disable RawInput if we have a mismatch of XInput-capable but not RawInput-capable devices

Updated to SDL 2.0.13 code with the following notes:
New HID driver: xbox360w - no idea what that is, hopefully urelated
SDL_hidapijoystick.c had been refactored to couple data handling logic with device opening logic and device lists caused some problems, yields slightly uglier integration than previously when the 360 HID device driver was just handling the data.
SDL_hidapijoystick.c now often pulls the device off of the joystick_hwdata structure for some rumble logic, but it appears that code path is never reached, so probably not a problem.
Looks like joystick_hwdata was refactored to not include a mutex in other drivers, maintainers may want to do the same refactor here if that's useful for some reason.
Something changed in how devices get names, so getting generic names.
Had to fix a (new?) bug where removing an XInput controller caused existing controllers (that moved to a new XInput index) to get identified as 0x045e/0x02fd ("it's probably Bluetooth" in code), rendering the existing HIDAPI_IsDevicePresent and new RAWINPUT_IsDevicePresent unreliable.

Sam Lantinga 2be75c6a61 Fixed bug 5028 - Virtual Joysticks (new joystick backend)
David Ludwig

I have created a new driver for SDL's Joystick and Game-Controller subsystem: a Virtual driver.  This driver allows one to create a software-based joystick, which to SDL applications will look and react like a real joystick, but whose state can be set programmatically.  A primary use case for this is to help enable developers to add touch-screen joysticks to their apps.

The driver comes with a set of new, public APIs, with functions to attach and detach joysticks, set virtual-joystick state, and to determine if a joystick is a virtual-one.

Use of virtual joysticks goes as such:

1. Attach one or more virtual joysticks by calling SDL_JoystickAttachVirtual.  If successful, this returns the virtual-device's joystick-index.
2. Open the virtual joysticks (using indicies returned by SDL_JoystickAttachVirtual).
3. Call any of the SDL_JoystickSetVirtual* functions when joystick-state changes.  Please note that virtual-joystick state will only get applied on the next call to SDL_JoystickUpdate, or when pumping or polling for SDL events (via SDL_PumpEvents or SDL_PollEvent).


Here is a listing of the new, public APIs, at present and subject to change:

------------------------------------------------------------

/**
 * Attaches a new virtual joystick.
 * Returns the joystick's device index, or -1 if an error occurred.
 */
extern DECLSPEC int SDLCALL SDL_JoystickAttachVirtual(SDL_JoystickType type, int naxes, int nballs, int nbuttons, int nhats);

/**
 * Detaches a virtual joystick
 * Returns 0 on success, or -1 if an error occurred.
 */
extern DECLSPEC int SDLCALL SDL_JoystickDetachVirtual(int device_index);

/**
 * Indicates whether or not a virtual-joystick is at a given device index.
 */
extern DECLSPEC SDL_bool SDLCALL SDL_JoystickIsVirtual(int device_index);

/**
 * Set values on an opened, virtual-joystick's controls.
 * Returns 0 on success, -1 on error.
 */
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualAxis(SDL_Joystick * joystick, int axis, Sint16 value);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualBall(SDL_Joystick * joystick, int ball, Sint16 xrel, Sint16 yrel);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualButton(SDL_Joystick * joystick, int button, Uint8 value);
extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualHat(SDL_Joystick * joystick, int hat, Uint8 value);

------------------------------------------------------------

Miscellaneous notes on the initial patch, which are also subject to change:

1. no test code is present in SDL, yet.  This should, perhaps, change.  Initial development was done with an ImGui-based app, which potentially is too thick for use in SDL-official.  If tests are to be added, what kind of tests?  Automated?  Graphical?

2. virtual game controllers can be created by calling SDL_JoystickAttachVirtual with a joystick-type of SDL_JOYSTICK_TYPE_GAME_CONTROLLER, with naxes (num axes) set to SDL_CONTROLLER_AXIS_MAX, and with nbuttons (num buttons) set to SDL_CONTROLLER_BUTTON_MAX.  When updating their state, values of type SDL_GameControllerAxis or SDL_GameControllerButton can be casted to an int and used for the control-index (in calls to SDL_JoystickSetVirtual* functions).

3. virtual joysticks' guids are mostly all-zeros with the exception of the last two bytes, the first of which is a 'v', to indicate that the guid is a virtual one, and the second of which is a SDL_JoystickType that has been converted into a Uint8.

4. virtual joysticks are ONLY turned into virtual game-controllers if and when their joystick-type is set to SDL_JOYSTICK_TYPE_GAMECONTROLLER.  This is controlled by having SDL's default list of game-controllers have a single entry for a virtual game controller (of guid, "00000000000000000000000000007601", which is subject to the guid-encoding described above).

5. regarding having to call SDL_JoystickUpdate, either directly or indirectly via SDL_PumpEvents or SDL_PollEvents, before new virtual-joystick state becomes active (as specified via SDL_JoystickSetVirtual* function-calls), this was done to match behavior found in SDL's other joystick drivers, almost all of which will only update SDL-state during SDL_JoystickUpdate.

6. the initial patch is based off of SDL 2.0.12

7. the virtual joystick subsystem is disabled by default.  It should be possible to enable it by building with SDL_JOYSTICK_VIRTUAL=1

Sam Lantinga 4b585e75d9 Fixed bug 4833 - Use EGL for X11?
Martin Fiedler

To be precise, this is about *desktop OpenGL* on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above.

To shine some light on why this is needed:
In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that *requires* the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.)
Some example code:
https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e
Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation.

The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX.

I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

Sam Lantinga 981e0d367c Fixed bug 4903 - Lack of color multiply with alpha (SDL_BLENDMODE_MOD + SDL_BLENDMODE_BLEND) blending mode for all renderers
Konrad

This kind of blending is rather quite useful and in my opinion should be available for all renderers. I do need it myself, but since I didn't want to use a custom blending mode which is supported only by certain renderers (e.g. not in software which is quite important for me) I did write implementation of SDL_BLENDMODE_MUL for all renderers altogether.

SDL_BLENDMODE_MUL implements following equation:

dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA))
dstA = (srcA * dstA) + (dstA * (1-srcA))

Sam Lantinga 5e19e66c73 Fixed bug 4914 - Expose SDL_ScaleMode and add SDL_SetTextureScaleMode/SDL_GetTextureScaleMode
Konrad

This was something rather trivial to add, but asked at least several times before (I did google about it as well).

It should be possible to dynamically change scaling mode of the texture. It is actually trivial task, but until now it was only possible with a hint before creating a texture.

I needed it for my game as well, so I took the liberty of writing it myself.

This patch adds following functions:

SDL_SetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode scaleMode);
SDL_GetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode *scaleMode);

That way you can change texture scaling on the fly.

Sam Lantinga 54748a39be Fixed bug 4890 - Add hint for SDL that the graphics context is externally managed
Aaron Barany

Add SDL_HINT_VIDEO_EXTERNAL_CONTEXT hint to notify SDL that the graphics context is external. This disables the automatic context save/restore behavior on Android and avoids using OpenGL by default when SDL_WINDOW_VUKLAN isn't set.

When the application wishes to manage the OpenGL contexts on Android, this avoids cases where SDL unbinds the context and creates new contexts, which can interfere with the application's operation.

When using Vulkan and Metal renderer implementations, this avoids SDL forcing OpenGL to be enabled on certain platforms. While using the SDL_WINDOW_VULKAN flag can be used to achieve the same thing, it also causes Vulkan to be loaded. If the application uses Vulkan directly, this is not necessary, and fails window creation when using Metal due to Vulkan not being present. (assuming MoltenVK isn't installed)

David Ludwig b13c951cca CMake: iOS support added
When using a recent version of CMake (3.14+), this should make it possible to:
- build SDL for iOS, both static and dynamic
- build SDL test apps (as iOS .app bundles)
- generate a working SDL_config.h for iOS (using SDL_config.h.cmake as a basis)

To use, set the following CMake variables when running CMake's configuration stage:
- CMAKE_SYSTEM_NAME=iOS
- CMAKE_OSX_SYSROOT=<SDK>  (examples: iphoneos, iphonesimulator, iphoneos12.4, /full/path/to/iPhoneOS.sdk, etc.)
- CMAKE_OSX_ARCHITECTURES=<semicolon-separated list of CPU architectures> (example: "arm64;armv7s")

Examples:
- for Simulator, using the latest, installed SDK:
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_ARCHITECTURES=x86_64

- for Device, using the latest, installed SDK, 64-bit only
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES=arm64

- for Device, using the latest, installed SDK, mixed 32/64 bit
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES="arm64;armv7s"

- for Device, using a specific SDK revision (iOS 12.4, in this example):
    cmake path/to/SDL -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos12.4 -DCMAKE_OSX_ARCHITECTURES=arm64

- for Simulator, using the latest, installed SDK, and building SDL test apps (as .app bundles):
    cmake path/to/SDL -DSDL_TEST=1 -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator -DCMAKE_OSX_ARCHITECTURES=x86_64

Sam Lantinga cc47810d36 Fixed bug 4683 - SDL_atomic infinite recursion on armv6/armv5 w/ thumb
The real problem is that SDL_atomic.c was built in thumb mode instead of ARM mode, which is required to use the mcr instruction on ARM platforms. Added a compiler error to catch this case so we don't generate code that does infinite recursion.

I also added a potentially better way to handle things on Linux ARM platforms, based on comments in the Chromium headers, which we can try out after 2.0.10 ships.

Sam Lantinga 69d27a69cd Fixed bug 4570 - Support Vulkan Portability rather than MoltenVK specifically
Dzmitry Malyshau

Current code, search paths, and error messages are written to only consider MoltenVK on macOS as a Vulkan Portability implementation. It's not the only implementation available to the users. gfx-portability [1] has been shown to run a number of titles well, including Dota2, Dolphin Emulator, and vkQuake3, often out-performing MoltenVK in frame rate and stability (see Dolphin benchmark [2]).

There is no reason for SDL to be that specific, it's not using any MVK-specific functions other than the WSI initialization ("VK_MVK_macos_surface"). gfx-portability exposes this extension as well, and a more generic WSI extension is in process. It would be good if SDL was written in a more generic way that expect a Vulkan Portability library as opposed to MoltenVK specifically.

Sam Lantinga 762b788f67 Cleanup on bug 3894 - Fuzzing crashes for SDL_LoadWAV
Simon Hug

Attached is a minor cleanup patch. It changes the option name of one hint to something better, puts one or two more checks in, and adds explicit casting where warnings could appear otherwise.

I hope the naming of the hints and their options is acceptable. It would be kind of awkward to change them after they get released with an official SDL version.

Sam Lantinga 990e166a3b Fixed bug 3894 - Fuzzing crashes for SDL_LoadWAV
Simon Hug

I had a look at this and made some additions to SDL_wave.c.

The attached patch adds many checks and error messages. For some reason I also added A-law and ?-law decoders. Forgot exactly why... but hey, they're small.

The WAVE format is seriously underspecified (at least by the documents that are publicly available on the internet) and it's a shame Microsoft never put something better out there. The language used in them is so loose at times, it's not surprising the encoders and decoders behave very differently. The Windows Media Player doesn't even support MS ADPCM correctly.

The patch also adds some hints to make the decoder more strict at the cost of compatibility with weird WAVE files.

I still think it needs a bit of cleaning up (Not happy with the MultiplySize function. Don't like the name and other SDL code may want to use something like this too.) and some duplicated code may be folded together. It does work in this state and I have thrown all kinds of WAVE files at it. The AFL files also pass with it and some even play (obviously just noise). Crafty little fuzzer.

Any critique would be welcome. I have a fork of SDL with a audio-loadwav branch over here if someone wants to use the commenting feature of Bitbucket:

https://bitbucket.org/ChliHug/SDL

I also cobbled some Lua scripts together to create WAVE test files:

Sam Lantinga 316ff3847b Fixed bug 4526 - replace SDL_RW* macros with functions for using in bindings
ace

I got this bug in SDL_ttf:
https://bugzilla.libsdl.org/show_bug.cgi?id=4524
Sylvain proposed solution:
SDL_RWseek(RWops, 0, RW_SEEK_SET);

And it works, but i can use it my project, because it written in C# with SDL2-CS wrapper and there not export for macroses:
#define SDL_RWsize(ctx)         (ctx)->size(ctx)
#define SDL_RWseek(ctx, offset, whence) (ctx)->seek(ctx, offset, whence)
#define SDL_RWtell(ctx)         (ctx)->seek(ctx, 0, RW_SEEK_CUR)
#define SDL_RWread(ctx, ptr, size, n)   (ctx)->read(ctx, ptr, size, n)
#define SDL_RWwrite(ctx, ptr, size, n)  (ctx)->write(ctx, ptr, size, n)
#define SDL_RWclose(ctx)        (ctx)->close(ctx)

Therefore, I suggest replacing this macros with functions so that they can be exported and used in bindings

Sam Lantinga ac15de18bd Fixed bug 4392 - SDL_cpuinfo.h breaks compilation with C bool type
Luke Dashjr

Bug 3993 was "fixed" by #undef'ing bool. But this breaks C99's stdbool.h bool too.

For example, mpv's build fails with:

../audio/out/ao_sdl.c:35:5: error: unknown type name ?bool?

It seems ill-advised to be #undef'ing *anything* here - what if the code including SDL_cpuinfo.h actually wants to use altivec?

Sam Lantinga b73703b9c6 Fixed bug 4391 - hid_enumerate() sometimes causes game to freeze for a few seconds
Daniel Gibson

Even though my game (dhewm3) doesn't use SDL_INIT_JOYSTICK, SDL_PumpEvent() calls SDL_JoystickUpdate() which ends up calling hid_enumerate() every three seconds, and sometimes on my Win7 box hid_enumerate() takes about 5 seconds, which causes the whole game to freeze for that time.

Sam Lantinga 1a4c0d4e17 Fixed bug 4377 - SDL_PIXELFORMAT enum is anonymous, which prevents its use in a templated function
zen3d

While trying to build Pixie lisp (https://github.com/pixie-lang/pixie), which uses SDL for multimedia output, the mandelbrot example won't build. The problem is that internally pixie uses a templated function to dump a value, and gcc chokes because SDL_PIXELFORMAT_RGA8888 is an anonymous enum.

I solved the problem locally by changing from:
   enum {
      SDL_PIXELFORMAT_UNKNOWN,
      ... etc. ...
      SDL_PIXELFORMAT_YUYV = ... etc ...
   };
to:
   typedef enum {
      SDL_PIXELFORMAT_UNKNOWN,
      ... etc. ...
      SDL_PIXELFORMAT_YUYV = ... etc ...
   } SDL_PIXELFORMAT_ENUM;
The net result of this change is that the enum containing SDL_PIXELFORMAT_* is no longer an anonymous enum and can now be used by a templated function.

This local change fixes Pixie lisp for me.

I did notice that you use the idiom
   typedef enum {
      ... etc ...
   } SDL_FOO;
elsewhere in your code, so that change to SDL_PIXELFORMAT doesn't look like it would have a negative impact.

Alex Szpakowski 5029d50ea8 Add SDL_TouchDeviceType enum and SDL_GetTouchDeviceType(SDL_TouchID id).

Phone screens are an example of a direct device type. Mac trackpads are the indirect-absolute touch device type. The Apple TV remote is an indirect-relative touch device type.
