* build: Split test programs off into separate filesDiego Biurrun2016-04-07
| | | | | This avoids spurious library rebuilds when only the test program code is changed and simplifies the build system.
* arm: add a cpu flag for the VFPv2 vector modeJanne Grunau2015-12-14
| | | | | | | | | | | | | | The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu implementations do not support it in hardware. Vector mode code will depending the OS either be emulated in software or result in an illegal instruction on cpus which does not support it. This was not really problem in practice since NEON implementations of the same functions are preferred. It will however become a problem for checkasm which tests every cpu flag separately. Since this is a cpu feature newer cpu do not support anymore the behaviour of this flag differs from the other flags. It can be only activated by runtime cpu feature selection.

* cpu-test: test av_cpu_countJanne Grunau2014-08-04
| | | | Add CPU count and number threads as informative values for fate.
* fate: add informative cpu testJanne Grunau2014-08-04
| | | | | | | | libavutil/cpu-test prints raw and effective cpu flags to STDERR. Detected cpu flags can be useful for debugging fate errors. No comparison of the result against a expected result since that would require fate config specific references.

* aarch64: add cpuflags support for NEON and VFPJanne Grunau2014-01-15
| | | | | | | NEON and VFP are currently mandatory for all ARMv8 profiles. Both are handled as extensions as far as cpuflags are concerned. This is consistent with handling x86_64 which always has SSE2, but still handles it as an extension.

* x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-03
| | | | | | | Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.

* avutil: add av_parse_cpu_flags() functionMans Rullgard2012-04-25

* ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-22
| | | | | | | This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* remove iwmmxt optimizationsJanne Grunau2012-03-12
| | | | | | The were broken since August of 2010 without anyone noticing until three weeks ago. Nobody cares about it anymore and hopefully Marvell will support NEON like in the PXA978 from now on.

* Add a CPU flag for the Atom processor.Justin Ruggles2011-03-22
| | | | | | | The Atom has SSSE3 support, which is useful in many cases, but sometimes the SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally faster on other processors supporting SSSE3. This flag allows for selectively disabling certain SSSE3 functions on the Atom.
