ab389226cd audio: Added ARM NEON versions of audio converters. 
These are _much_ faster than the scalar equivalents on the Raspberry Pi that
I tested on. Often 3x to 4x as fast!

cc16ae0ff1 cpuinfo: Added SDL_HasAVX512F(). 
This checks for the "foundation" AVX-512 instructions (that all AVX-512
compatible CPUs support).

b997193f84 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)

aff3beaca5 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.

7cd440646f Fixed building SDL applications with Visual Studio and the clang toolset 
Also fixed building 64-bit SDL with clang. 32-bit doesn't build because of the inline assembly for C runtime support.

921f2abe11 Fixed bug 2376 - no SDL_HasAVX 
Haneef Mubarak

AVX is the successor to SSE* and is fairly widely available. As such, it really ought to be detectable.

This functionality ought to be trivial to implement, and not having it means being forced to write an ugly workaround to check for AVX (so that normal SSE can be used if AVX is not available).

Here is an example on detecting AVX from SO (it actually shows ways to cehck for all of teh fancy instructions):

b3b40aac16 Removed Windows CE support from SDL 2.0. 
It's a long-dead platform, and we don't have any way to build for, test, or
maintain it, so there's no sense in doing acrobatics to support it.

If you need Windows CE support, use SDL 1.2. If you need Windows Phone support,
send SDL 2.0 patches for the newer Windows Mobile platform.
