Anton Khirnov	24a362569b	buffer: fix av_buffer_realloc() when the data is offset wrt buffer start In such a case behave as if the buffer was not reallocatable -- allocate a new one and copy the data (preserving just the part described by the reference passed to av_buffer_realloc).

Ronald S. Bultje	9790b44a89	vp9mc/x86: sse2 MC assembly. Also a slight change to the ssse3 code, which prevents a theoretical overflow in the sharp filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago

Martin Storsjö	fc94a1acc2	Revert "libavutil: Use an intermediate variable in AV_COPYU" This reverts commit `014773b66b`. Since `230b1c070`, the bytewise AV_W() macros only expand their argument once, i.e. doing exactly the same change as was done in the AV_COPY*U macros, so this change is no longer necessary.

Martin Storsjö	9806b9ab5c	Revert "Don't use expressions with side effects in macro parameters" This reverts commit `25bacd0a0c`. Since `230b1c070`, the bytewise AV_W*() macros only expand their argument once, so revert to the more readable version of these. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Martin Storsjö	f79d847400	intreadwrite: Use the __unaligned keyword on MSVC for ARM and x86_64 AV_WN64 is meant for unaligned data, but the existing av_alias* unions (without a definition for the av_alias attribute - we don't have one for MSVC) indicate to the compiler that they would have sufficient alignment for normal access, i.e. the compiler is free to assume 8 byte alignment. On ARM, this makes sure that AV_WN64 (or two consecutive AV_WN32) is done with two str instructions instead of one strd. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Martin Storsjö	230b1c070b	intreadwrite: Add intermediate variables in the byteswise AV_W*() macros This avoids issues with expanding the argument multiple times, and makes sure that it is of the right type for the following shifts. Even if the caller of a macro could be expected not to pass parameters that have side effects if expanded multiple times, these fallback codepaths are rarely, if ever, tested, so it is expected that such issues can arise. Thefore, for safety, make sure the fallback codepaths only expand the arguments once. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Martin Storsjö	014773b66b	libavutil: Use an intermediate variable in AV_COPY*U If AV_RN and AV_WN are macros with multiple individual reads and writes, the previous version of the AV_COPYU macro would fail if the reads and writes overlap. This should not be any less efficient in any case, given a sensibly optimizing compiler. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Martin Storsjö	25bacd0a0c	Don't use expressions with side effects in macro parameters AV_WB32 can be implemented as a macro that expands its parameters multiple times (in case AV_HAVE_FAST_UNALIGNED isn't set and the compiler doesn't support GCC attributes); make sure not to read multiple times from the source in this case.

Anton Khirnov	a115eb9e75	mimic: do not release the newly obsolete reference at the end of decoding The reference frames are used in update_thread_context(), so modifying them after finish_setup() is a race.
