David Ludwig ff5caa17 2014-08-10T22:21:21 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.
Sam Lantinga 454c4a01 2014-07-11T22:15:34 Fixed Visual Studio 2010 build
Sam Lantinga 6a1011ae 2014-07-11T22:14:14 Fixed build for arm platforms
Sam Lantinga eb1c6044 2014-07-11T22:02:50 Fixed bug in AVX detection and added AVX2 detection
David Ludwig 3dcb451f 2014-04-09T21:29:19 Added a README file regarding WinRT support To note, this file is currently formatted with CRLF line endings, rather than LF, to allow the file to be viewed with Notepad.

Sam Lantinga 9cd5f5ce 2014-02-22T19:10:45 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.
Sam Lantinga fea87cc9 2014-02-22T18:01:18 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.

Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Sam Lantinga 3bd0e900 2014-02-02T00:33:31 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): http://stackoverflow.com/questions/6121792/how-to-check-if-a-cpu-supports-the-sse3-instruction-set
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.
Ryan C. Gordon 72de99ae 2013-10-23T19:52:14 Initialize MEMORYSTATUSEX size before GlobalMemoryStatusEx() (thanks, Justin!). Fixes Bugzilla #2177.
Sam Lantinga 08fa8da7 2013-10-20T21:56:15 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/5486e579872e / 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.
Sam Lantinga 12ca3ce3 2013-10-17T23:02:29 Fixed building using MinGW Our SDL_windows.h needed to be included before anything else so UNICODE is defined.
Sam Lantinga 95dc9940 2013-10-17T20:49:30 Fix to unbreak SDL_GetSystemRAM() on FreeBSD Marcus von Appen Revision eecbcfed77c9 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.
Sam Lantinga 2e6b4b96 2013-10-17T11:56:33 Fixed compiling on Mac OS X, added a system RAM test
Sam Lantinga 8b79cbad 2013-10-17T11:32:56 Added an API to get the amount of system RAM
Sam Lantinga 852004a2 2013-10-17T11:32:14 The _SC_PHYS_PAGES method of calculating RAM works on Linux.
Gabriel Jacobo dad42067 2013-08-12T11:13:50 Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
Sam Lantinga 1ad936eb 2013-08-11T19:56:43 Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.
