* 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

| | | | The compiler is free to optimize such expressions in any sort of way.
* pixfmt: remove misleading and broken documentationwm42015-05-28
| | | | | | | | | | | | | | | | | | | | This was probably broken some time ago. The breakage is now part of the ABI. For example, we have: AV_PIX_FMT_XYZ12BE AV_PIX_FMT_NV16 AV_PIX_FMT_NV20LE AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian format it should be even. This must have been quite obvious when these formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but nobody cared or knew about this. The future libavutil major bump will also break this additionally, because disabling FF_API_VDPAU will remove an odd number of entries from the middle of the enum.

* x86inc: Clear __SECT__Timothy Gu2015-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Silences warning(s) like: libavcodec/x86/fft.asm:93: warning: section flags ignored on section redeclaration The cause of this warning is that because `struc` and `endstruc` attempts to revert to the previous section state [1]. The section state is stored in the macro __SECT__, defined by x86inc.asm to be `.note.GNU-stack ...`, through the `SECTION` directive [2]. Thus, the `.note.GNU-stack` section is defined twice (once in x86inc.asm, once during `endstruc`), causing the warning. That is the first part of the commit: using the primitive `[section]` format for .note.GNU-stack etc., which does not update `__SECT__` [2]. That fixes only half of the problem. Even without any `SECTION` directives, `__SECT__` is predefined as `.text`, which conflicting with the later `SECTION_TEXT` (which expands to `.text align=16`).
