de88474dda Initial merge of Emscripten port!
With this commit, you can compile SDL2 with Emscripten
( http://emscripten.org/ ), and make your SDL-based C/C++ program
into a web app.

This port was due to the efforts of several people, including: Charlie Birks,
Sathyanarayanan Gunasekaran, Jukka Jylänki, Alon Zakai, Edward Rudd,
Bruce Mitchener, and Martin Gerhardy. (Thanks, everyone!)

587dd65dec WinRT build fix for ARM platforms
The _xgetbv intrinsic was being used in ARM builds of SDL/WinRT, which was
leading to linker errors.  This commit limits _xgetbv use to the platforms on
which it is available, x86 and x64.

3b9df91fd6 Fixed bug 2404 - CPU detection not working with MSVC on x64
Tiemo Jung

All CPU detection functions SDL_Has* will return false, even if it is supported by the CPU, if SDL is compiled with MSVC and the target is x64.

The reason for this is that 'CPU_haveCPUID' will return 0 and macro 'cpuid' in SDL_cpuinfo.c is the fallback implementation, which sets all params to zero.

It is safe to assume that cpuid is supported on a CPU that runs windows x64, so CPU_haveCPUID can just return 1, and the empty macro can be replaced with a small wrap around the __cpuid intrinsic.

1dfdcf3ef4 Fixed bug 2335 - Fails to build on Debian GNU/kFreeBSD
Felix Geyer

Starting from version 2.0.1 libsdl fails to build on Debian GNU/kFreeBSD in SDL_cpuinfo.c.

GNU/kFreeBSD defines __FreeBSD_kernel__ but not __FreeBSD__.
The #ifdef __FreeBSD__ check should be extended for __FreeBSD_kernel__, see the attached patch.

420a70436c 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):

44dbed38ac Fixed bug 2129 - fix for bug 2121 breaks linking for mingw and throws multiple warnings
Andreas Ertelt

The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/4434498bf4b9 / https://bugzilla.libsdl.org/show_bug.cgi?id=2121)

The redefinition of __inline__ (introduced by the addition of begin_code.h:128's "|| __STRICT_ANSI__") results in mingw's gcc throwing multiple

   warning: always_inline function might not be inlinable [-Wattributes]

as well as a whole bunch of redefinitions of mingw internals which break linking of projects including the SDL2 headers.

22648bd334 Fix to unbreak SDL_GetSystemRAM() on FreeBSD
Marcus von Appen

Revision c47ae79f0de8 of the SDL hg repo introduces the new
SDL_GetSystemRAM() function, which breaks the build on FreeBSD. Find
attached a patch, which unbreaks the build and also should (for most
cases) properly implement the sysctl support it.

b4497865bd Include windows.h in a single point in the source, so we can be consistent about the definition of UNICODE and have core utility functions for Windows that all modules can share.
I think this also fixes the bug relating to non-latin characters in filenames, since UNICODE wasn't defined in SDL_rwops.c
