cbdee4d656 [ SDL ] Fix compile error building for Windows/ARM64 on Visual Studio 2017 Win10 SDK 10.0.18362.0 which requires ar,74intr.h/arm64_neon.h header instead of armintr.h/arm_neon.h for intrinsics.

8728ce4448 Fixed bug 4557 - SDL_SIMDAlloc and *Free should be in the public interface
Martin Gerhardy

These functions are really useful and should get exposed imo.

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?

b7e88aaae0 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!

4df859c586 cpuinfo: Added SDL_HasAVX512F().
This checks for the "foundation" AVX-512 instructions (that all AVX-512
compatible CPUs support).

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.

Also fixed building 64-bit SDL with clang. 32-bit doesn't build because of the inline assembly for C runtime support.

0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
