* libavutil: Add ARM av_clip_intp2_armPeter Meerwald2015-02-21
| | | | | | | | | | add ARM code for implementing av_clip_intp2 using the ssat instruction on Cortex-A8, av_clip_intp2_arm() is faster than av_clip_intp2_c() and the generic av_clip(), about -19% Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* arm: use HAVE*_INLINE/EXTERNAL macros for conditional compilationMans Rullgard2012-12-07
| | | | | | These macros reflect the actual capabilities required here. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Move avutil tables only used in libavcodec to libavcodec.Diego Biurrun2012-10-11

* ARM: intmath: use native-size return types for clipping functionsMans Rullgard2012-08-13
| | | | | | | This avoids having the compiler redundantly mask the values to the smaller size. Signed-off-by: Mans Rullgard <mans@mansr.com>
* libavutil: add saturating addition functionsMans Rullgard2012-08-13
| | | | | | | Fixed-point audio codecs often use saturating arithmetic, and special instructions for these operations are common. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: add missing "cc" clobber in av_clipl_int32_arm()Mans Rullgard2012-08-10

* ARM: use Q/R inline asm operand modifiers only if supportedMans Rullgard2012-08-07
| | | | | | | | | | Some compilers do not support the Q/R modifiers used to access the low/high parts of a 64-bit register pair. Check for this and disable all uses of it when not supported. Fixes bug #337. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: allow building in Thumb2 modeMans Rullgard2011-06-23

* ARM: improve FASTDIV asmMans Rullgard2011-05-28
| | | | | | This uses one register less. Also add missing "cc" clobber. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: add ARMv6 optimised av_clip_uintp2Mans Rullgard2011-05-26

* ARM: remove volatile from asm statements in libavutil/intmathMans Rullgard2011-05-26
| | | | | | | The volatile qualifiers are not needed on these statements as their effects are fully specified by constraints. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: fix av_clipl_int32_arm()Mans Rullgard2011-05-26

* Force inlining of avutil common routinesJason Garrett-Glaser2011-02-17
| | | | | | On some versions of gcc, these weren't always getting inlined due to hitting the inline cap limit in some files. This is generally bad, as most of these functions are smaller inlined than not.

* Replace many includes of libavutil/common.h with what is actually neededMåns Rullgård2010-03-09
| | | | | | | This reduces the number of false dependencies on header files and speeds up compilation. Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk
