* avcodec: increase AV_INPUT_BUFFER_PADDING_SIZE to 64James Almer2018-01-11
| | | | | | | | | | AVX-512 support has been introduced, and even if no functions currently use zmm registers (able to load as much as 64 bytes of consecutive data per instruction), they will be added eventually.

* avcodec/fft: fix INTERL macro on 3dnowMikulas Patocka2017-11-25
| | | | | | | | | | | | | The commit b7c16a3f2c4921f613319938b8ee0e3d6fa83e8d ("x86: fft: Port to cpuflags") breaks the opus decoder in ffmpeg when compiling for 3dnow. The output is audible, but there's a lot of noise. The reason for the breakage is that the commit unintentionally changed the INTERL macro so that it is empty when compiling for 3dnow. This patch fixes it. Signed-off-by: Mikulas Patocka <mikulas@twibright.com> Signed-off-by: James Almer <jamrial@gmail.com>

* Fix missing used attribute for inline assembly variablesThomas Köppe2017-11-13
| | | | | | | | | | | | | Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
