Ryan C. Gordon 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!

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

Ryan C. Gordon 8543ad7df1 cpuinfo: Added some internal SIMD-aligned allocation functions.
Fixes Bugzilla  (sort of).

Sam Lantinga 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)

Sam Lantinga 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.

Sam Lantinga f1ec8a5f4c Check for immintrin.h before using it in SDL_cpuinfo.h 2017-12-11 12:00:12 -08:00
Sam Lantinga 846d008036 Only include Intel intrinsics header on x86 and x64 2017-11-11 16:20:00 -08:00
Sam Lantinga 4026db8c7e Replaced the intrinsics header with the single header that includes all intrinsics so we can use AVX, etc. 2017-11-10 14:22:21 -08:00
Sam Lantinga 30d554e3d6 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.

Philipp Wiesemann 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().
