Anonymous Maarten 44903d8a 2023-07-22T21:20:34 SDL_atomic.h: __ARM_ARCH is not always defined for an arm platform e.g. riscos toolchain (cherry picked from commit 8105f1d5b5b83328f4d0017a562674efca821077)
Jiří Malák 507fc462 2023-01-26T15:00:02 SDL_atomic.h: Update SDL_CPUPauseInstruction for Watcom. (#7157) Appropriate CPU directive can be used in #pragma aux so that it is not necessary to hardcode instruction bytes.

Oleg Derevenetz a204ef50 2022-08-19T22:16:04 Use __ARM_ARCH instead of __ARM_ARCH__
David Carlier 16e699a7 2022-08-01T07:59:04 Proposing exposing as public api the various arch dependent pause instructions so could be used in app infinite loops. A handful of games do already so we unify it in one place.

Sam Lantinga 959cfc42 2019-06-30T23:58:31 Fixed memory barrier macro check so it isn't quite so fragile
Sam Lantinga cc47810d 2019-06-30T23:26:16 Fixed bug 4683 - SDL_atomic infinite recursion on armv6/armv5 w/ thumb The real problem is that SDL_atomic.c was built in thumb mode instead of ARM mode, which is required to use the mcr instruction on ARM platforms. Added a compiler error to catch this case so we don't generate code that does infinite recursion. I also added a potentially better way to handle things on Linux ARM platforms, based on comments in the Chromium headers, which we can try out after 2.0.10 ships.

Sam Lantinga 30d554e3 2017-08-19T03:07:44 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.

Sam Lantinga b4e069e7 2016-12-26T02:12:21 Fixed bug 3517 - Compiler warnings with gcc -Wstrict-prototypes felix Compiling even a simple SDL2 'hello world' program with gcc -Wstrict-prototypes (GCC 6.2.1) results in warnings like: /usr/include/SDL2/SDL_gamecontroller.h:143:1: attention : function declaration isn't a prototype [-Wstrict-prototypes] extern DECLSPEC int SDLCALL SDL_GameControllerNumMappings(); ^~~~~~ It seems there is a missing 'void' between the parentheses.

Philipp Wiesemann 0e45984f 2015-06-21T17:33:46 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().

Ryan C. Gordon b72938c8 2015-04-20T12:22:44 Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.

Edward Rudd b88ca1b4 2015-02-10T16:28:56 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
Philipp Wiesemann b48e54aa 2015-01-26T22:00:29 Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
Ryan C. Gordon fe40a172 2014-12-18T00:19:52 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 Jyl?nki, Alon Zakai, Edward Rudd, Bruce Mitchener, and Martin Gerhardy. (Thanks, everyone!)
David Ludwig 70438be2 2014-12-03T10:55:23 WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!

Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam

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.
