02daab87 | 2021-07-29 18:09:38 | Fix pointer provenance in SDL_SIMDRealloc This is needed to support CHERI, and thus Arm's experimental Morello prototype, where pointers are implemented using unforgeable capabilities that include bounds and permissions metadata to provide fine-grained spatial and referential memory safety, as well as revocation by sweeping memory to provide heap temporal memory safety. The C standard does not guarantee that if two pointers compare equal they are the same pointer, as C pointers have a notion of provenance, and compilers have been known to exploit this during optimisation. For CHERI, this becomes even more important, as in-place expansion can result in realloc returning a capability to the same address but with increased capability bounds, and so reusing the old capability will trap trying to access outside the bounds of the original allocation. In the case that ptr == mem, memdiff and ptrdiff should still be equal, so the only overhead is a small amount of pointer arithmetic and a store of the new pointer (which is required per the C standard in order to not be undefined behaviour when next loaded). This also fixes the calculation of oldmem to use uintptr_t rather than size_t as casting the pointer to size_t on CHERI will strip the capability metadata, including the validity tag, with the subsequent cast back to void * resulting in a null-derived capability whose validity tag is clear and thus cannot be dereferenced without trapping. | |

c1c4f274 | 2021-03-04 18:27:32 | cpuinfo: updated xgetbv call for windows clang-cl. from a patchset by Vladislav Dmitrievich Turbanov: https://github.com/libsdl-org/SDL/pull/4062 | |
 |
61586216 | 2021-03-02 21:39:38 | Update cpuid code for clang-cl The clang-cl compiler defines `__llvm__` but not `__GNUC__`. The `__cpuid` intrinsic doesn't seem to exist with clang-cl, so the code won't link properly. The `__GNUC__` versions of these functions will work properly on Windows with clang-cl. | |

67f0b9b8 | 2020-12-28 20:58:47 | Fixed bug 5418 - Add system features detection for Elbrus (E2K) Ivan Kuzmenko MCST Elbrus 2000 (E2K, https://en.wikipedia.org/wiki/Elbrus_2000) is a russian processor architecture based on VLIW/EPIC instruction set (like Intel Itanium (IA-64) architecture). Architecture has half native / half software support of most Intel/AMD SIMD (e.g. MMX/SSE/SSE2/SSE3/SSSE3/SSE4.1/SSE4.2/AES/AVX/AVX2 & 3DNow!/SSE4a/XOP/FMA4). It also has built-in x86/x86_64 <-> e2k binary translators (RTC, http://www.mcst.ru/rtc and Lintel, http://www.mcst.ru/lintel) that can run code for x86/x86_64 architecture (Transmeta did something similiar with their Crusoe series) with SIMD extensions support. Attached patch allows SDL2 to detect extensions supported by E2K like MMX, 3dNOW!, AVX etc. (test/testplatform log: https://termbin.com/7qs3). | |

0e45984f | 2015-06-21 17:33:46 | 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(). | |

b88ca1b4 | 2015-02-10 16:28:56 | 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 | |

b48e54aa | 2015-01-26 22:00:29 | 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. | |

fe40a172 | 2014-12-18 00:19:52 | 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!) | |

70438be2 | 2014-12-03 10:55:23 | 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! | |

24c86b55 | 2014-09-11 19:24:42 | [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 | |

ff5caa17 | 2014-08-10 22:21:21 | 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. | |

9cd5f5ce | 2014-02-22 19:10:45 | 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. | |

3bd0e900 | 2014-02-02 00:33:31 | 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 | |
