* ppc: vsx: Implement diff_pixels and get_pixelsLuca Barbato2015-05-31
| | | | Use a macro to abstract the endianness.
* ppc: vsx: Implement float_dspLuca Barbato2015-05-31
|
* ppc: cpu: Add support for VSX and POWER8 extensionsLuca Barbato2015-05-31
|
* ppc: Restrict some Altivec implementations to Big EndianLuca Barbato2015-05-31
| | | | | In Little Endian the vec_ld/vec_st operations work as expected only for byte-vectors.
* ppc: Clarify and extend the cpuid checkLuca Barbato2015-05-31
| | | | Add POWER entries.
* ppc: linux: Check altivec using the auxvLuca Barbato2015-05-31
| | | | Should prevent trying to use altivec when it is disabled by the kernel.
* ppc: avutil: Use the abriged vector typesLuca Barbato2015-05-31
|
* ppc: avutil: Drop a potentially dangerous workaroundLuca Barbato2015-05-31
| | | | The compiler is free to optimize such expressions in any sort of way.
* ppc: Support little endian intreadwriteLuca Barbato2014-09-03
|
* ppc: Move vec_unaligned_load macro to util_altivecDiego Biurrun2014-05-28
| | | | This allows reusing it from multiple files.
* ppc: util_altivec: Drop unused macrosDiego Biurrun2014-05-28
|
* ppc: Add and use convenience macro to check for AltiVec availabilityDiego Biurrun2013-08-28
|
* avutil: Move internal CPU detection function declarations to private headerDiego Biurrun2013-08-28
|
* Consistently use "cpu_flags" as variable/parameter name for CPU flagsDiego Biurrun2013-07-18
|
* configure: Check for support for labels in the inline assemblyMartin Storsjö2013-07-11
| | | | | | | Use this for enabling the ppc timer.h implementation only on assemblers that support labels in the inline assembly. Signed-off-by: Martin Storsjö <martin@martin.st>
* avutil: Add av_cold attributes to init functions missing themDiego Biurrun2013-05-04
|
* ppc: util_altivec: Surround AltiVec-related code by appropriate ifdefsDiego Biurrun2013-04-30
| | | | This prevents non-AltiVec-enabled compilers from choking.
* cosmetics: Remove unnecessary extern keywords from function declarationsDiego Biurrun2013-03-27
|
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.
* floatdsp: move vector_fmul_add from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22

* lavc: Move vector_fmul_window to AVFloatDSPContextJustin Ruggles2013-01-16
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* float_dsp: ppc: add a separate header for Altivec function prototypesJustin Ruggles2012-06-08
| | | | | Also include config.h so that HAVE_ALTIVEC will be defined. Fixes compilation on PPC with Altivec enabled.
* Add a float DSP framework to libavutilJustin Ruggles2012-06-08
| | | | Move vector_fmul() from DSPContext to AVFloatDSPContext.
* PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutilJustin Ruggles2012-06-08
| | | | | This will allow for easier implementation of Altivec functions in libraries other than libavcodec.
* build: Move all arch OBJS declarations into arch subdirectory Makefiles.Diego Biurrun2012-04-12

* configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun2011-05-12
| | | | | | | | | | | | | | | | Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.
* os: fix OpenBSD/PowerPC compilationBrad2011-04-10
| | | | | | | | When attempting to re-enable the AltiVec support it was noticed that we need to undefine _POSIX_C_SOURCE to appease the headers for ff_get_cpu_flags_ppc() to be able to compile. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* Clean up av_get_cpu_flag()Måns Rullgård2010-09-09
| | | | | | | | Instead of defining functions in per-arch header files included by the main cpu.c, define them normally and call them from the generic one. Originally committed as revision 25084 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move mm_support() from libavcodec to libavutil, make it a publicStefano Sabatini2010-09-08
| | | | | | function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk

* PPC: fix asm operand constraints in AV_RL64Måns Rullgård2009-07-29
| | | | | | The target register of first word loaded must be marked early-clobber. Originally committed as revision 19536 to svn://svn.ffmpeg.org/ffmpeg/trunk

* PPC asm for AV_RL*()Måns Rullgård2009-04-18
| | | | | | | | | | | | PPC is normally big endian but has special little endian load/store instructions. Using these avoids a separate byteswap. This makes the vorbis decoder about 5% faster. Not much else uses little-endian read/write extensively. GCC generates horrible PPC code for the default AV_[RW]B64 (which uses a packed struct), so we override it with a plain pointer cast.

* Split libavutil/timer.h per architectureMåns Rullgård2009-04-01
