* mips: intreadwrite: Only execute that code for mips r1 or r2Vicente Olivert Riera2015-09-29
| | | | | | | | | MIPS R6 supports unaligned memory access and does not have the load/store-left/right family of instructions. Signed-off-by: Vicente Olivert Riera <Vincent.Riera at imgtec.com> Signed-off-by: Luca Barbato <lu_zero at gentoo.org> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* pixdesc: Consistently order componentsHendrik Leppkes2015-09-10
| | | | | | | | Ensure that the components are ordered consistently, ie. always RGB(A) and YUV(A). This allows to identify a specific plane on a given pixel format without hard-coding knowledge of the plane order. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavu: Drop the {minus,plus}1 suffix from AVComponentDescriptor fieldsVittorio Giovara2015-09-07
| | | | | | The new fields can be accessed directly and are more intelligible. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* lavu: Remove bit packing from AVComponentDescriptorVittorio Giovara2015-09-07
| | | | | | | | | There is no practical benefit in having this structure elements bit packed given the size of the structure and its usage. Change types from uint16_t (packed) to plain int in order to simplify modifying the structure and accessing its fields. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* x86inc: Drop SECTION_TEXT macroHenrik Gramner2015-08-11
| | | | | | | The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* x86inc: Support arbitrary stack alignmentsHenrik Gramner2015-08-11
| | | | | | | | Change ALLOC_STACK to always align the stack before allocating stack space for consistency. Previously alignment would occur either before or after allocating stack space depending on whether manual alignment was required or not. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* x86inc: warn if XOP integer FMA instruction emulation is impossibleAnton Mitrofanov2015-08-11
| | | | | | | | | | | Emulation requires a temporary register if arguments 1 and 4 are the same; this doesn't obey the semantics of the original instruction, so we can't emulate that in x86inc. Also add pmacsdql emulation. Signed-off-by: Henrik Gramner <henrik@gramner.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* x86: Serialize rdtsc in read_time()Henrik Gramner2015-07-09
| | | | | | | | | | | | | | | | | Improves the accuracy of measurements, especially in short sections. To quote the Intel 64 and IA-32 Architectures Software Developer's Manual: "The RDTSC instruction is not a serializing instruction. It does not necessarily wait until all previous instructions have been executed before reading the counter. Similarly, subsequent instructions may begin execution before the read operation is performed. If software requires RDTSC to be executed only after all previous instructions have completed locally, it can either use RDTSCP (if the processor supports that instruction) or execute the sequence LFENCE;RDTSC." SSE2 is a requirement for lfence so only use it on SSE2-capable systems. Prefer lfence;rdtsc over rdtscp since rdtscp is supported on fewer systems. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavu: Add version information for av_version_info()Vittorio Giovara2015-07-03
| | | | Move the APIchange entry at the top.
* lavu: add an API function to return the Libav version stringwm42015-07-02
| | | | | | | | This returns something like "v12_dev0-1332-g333a27c". This is much more useful than the individual library versions, of which there are too many, and which are very hard to map back to releases or git commits. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* configure: Support MSVC 2015Luca Barbato2015-06-08
| | | | | | | | | | | The C runtime C99 compatibility had been improved a lot and it now rejects some of the compatibility defines provided for the older versions. Many thanks to Ray for the time spent testing. Bug-Id: 864 CC: libav-stable@libav.org
