1c3a1e1139 wikiheaders: Updated to latest, cleaned up category documentation a little. 
This documentation needs a LOT of work--maybe someday--but it's definitely not
_broken_ right now, which is good enough for now.

b6e7c743db SDL_cpuinfo: define __ARM_ARCH=8 for _M_ARM64 
Microsoft's compiler doesn't define __ARM_ARCH, but we have several
places that use it.

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.

09b462044f Windows: NEON detection and intrinsic includes on Visual Studio 
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).

aea7e56a24 android: use __ARM_NEON instead of __ARM_NEON__ to include <arm_neon.h> 
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.

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?

These are _much_ faster than the scalar equivalents on the Raspberry Pi that
I tested on. Often 3x to 4x as fast!

6d39e67bad Fixed bug 4103 - SDL_cpuinfo.h provokes warnings with -Wundef on non-x86 hosts 
Felix Geyer

Forwarding from https://bugs.debian.org/892087 quoting verbatim:

The SDL2 header SDL_cpuinfo.h generates gcc warnings if the program using
it compiles with the -Wundef warning. (In particular, this means that QEMU
builds using it fail on at least sparc hosts, since QEMU dev builds
use both -Wundef and -Werror.).

/usr/include/SDL2/SDL_cpuinfo.h:63:5: warning: "HAVE_IMMINTRIN_H" is not defined, evaluates to 0 [-Wundef]
 #if HAVE_IMMINTRIN_H && !defined(SDL_DISABLE_IMMINTRIN_H)

0597bf6e99 Fixed bug 3993 - altivec.h include in SDL_cpuinfo.h breaks compilation with -std=c++11 
bastien.bouclet

According to this GCC bug report, altivec.h requires building with the gnu extensions: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78263.

As an application developer, I don't want SDL to force me to enable the gnu extensions.
