Visual Studio doesn't define __ARM_ARCH nor _ARM_NEON, but _M_ARM and _M_ARM64,
so SDL_HasNEON() was bypassed.
PF_ARM_NEON_INSTRUCTIONS_AVAILABLE doesn't see to be defined (but still works
when defined as 19).
Only __ARM_NEON is defined with Android NDK and arm64-v8a
Tested on ndk-r18, ndk-r13 and also Xcode.
(Visual Studio needs a different fix).
Fixes Bugzilla #4409.
* Search for valid encoder in connector when it doesn't have an
encoder ID set.
* Search for valid CRTC in resources and encoder's possible CRTCs
when encoder doesn't have one set.
* Select default mode if CRTC doesn't have a valid one.
* Pick current_mode's W/H/Refresh Rate basing on current and
valid CRTC mode, not the saved one.

After updating to SDL 2.0.9, I got a user report that my app was crashing when closing a SDL_WINDOW_FULLSCREEN window to return to my Qt-based UI. It looks like the dead SDL window is getting a spurious updateLayer call which is causing SDL to dereference a null SDL_WindowData pointer.
For some reason, this only happens when using SDL_WINDOW_FULLSCREEN and not windowed or SDL_WINDOW_FULLSCREEN_DESKTOP. I was also unsuccessful in my attempt to get a simple reproducer for this crash. The Session.cpp code is available 688c4a90d9/app/streaming/session.cpp but I slightly modified it (adding a SDL_PumpEvents() call at 1179 to immediately trigger the issue, otherwise it happened when Qt next pumped the event loop).
The crashing line is:
NSMutableArray *contexts = data->nscontexts;

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?

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.

The Dualshock 3's motion sensors don't seem to be reported by the call to EVIOCGBIT but they still send EV_ABS events. Because they're not reported by EVIOCGBIT they're not assigned a proper axis ids and the default of 0 is used, which is the valid id for the left analog sticks left/right axis.

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.
