* arm: hpeldsp: prevent overreads in armv6 asmJanne Grunau2014-03-05
| | | | | | | Based on a patch by Russel King <rmk+libav@arm.linux.org.uk> Bug-Id: 646 CC: libav-stable@libav.org
* arm: dcadsp: implement decode_hf as external NEON asmJanne Grunau2014-02-28
|
* dcadec: simplify decoding of VQ high frequenciesChristophe Gisquet2014-02-28
| | | | | | | | | | | | | | | | | | | The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.
* dcadec: remove scaling in lfe_interpolation_firChristophe Gisquet2014-02-28
| | | | | | | The scaling factor is constant so it is faster to scale the FIR coefficients in the tables during compilation. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* arm: Remove a stray .fpu directiveMartin Storsjö2014-02-09

* dca: include dcadsp.h in {arm,x86}/dca.h for checkheadersJanne Grunau2014-02-08

* dcadsp: split lfe_dir casesChristophe Gisquet2014-02-07
| | | | | | | | | The x86 runs short on registers because numerous elements are not static. In addition, splitting them allows more optimized code, at least for x86. Arm asm changes by Janne Grunau. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* dcadsp: add int8x8_fmul_int32 to dsp contextChristophe Gisquet2014-02-07
| | | | | | | | | | | | | | It is currently declared as a macro who is set to inlinable functions, among which a Neon and a default C implementations. Add a DSP parameter to each inline function, unused except by the default C implementation which calls a function from the DSP context. On an Arrandale CPU, gain for an inlined SSE2 function vs. a call: - Win32: 29 to 26 cycles - Win64: 25 to 23 cycles Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* arm: Add X() around all references to extern symbolsMartin Storsjö2014-02-07
| | | | | | Don't rely on the fact that an unprefixed label currently exists. Signed-off-by: Martin Storsjö <martin@martin.st>
* vp8: Use 2 registers for dst_stride and src_stride in neon bilin filterMartin Storsjö2014-02-06

* arm: Add an option for making sure NEON registers aren't clobberedMartin Storsjö2014-01-11
| | | | | | This is pretty much based on the same test for XMM registers. Signed-off-by: Martin Storsjö <martin@martin.st>
* arm: Add a missing # as prefix for an immediate constantMartin Storsjö2014-01-07
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* arm: Allow overriding the alignment set in the function macroMartin Storsjö2014-01-07
| | | | | | | | | | | | | | | The function macro always sets .align 2 before declaring the function label (since 5c5e1ea3) and always sets the section to .text (since 278caa6a). The .align 5 before certain functions, added in fc252eba, were added before .text and .align were added to the function macro and thus became useless/unused when the function macro got them. This restores the original intention, to align the loop entry points. Signed-off-by: Martin Storsjö <martin@martin.st>
* arm: Remove a leftover define for the pld instructionMartin Storsjö2014-01-07
| | | | | | | This file no longer uses the pld instruction at all, all such uses have been split into hpeldsp_arm.S. Signed-off-by: Martin Storsjö <martin@martin.st>
* arm: cosmetics: Reindent the h264dsp neon init functionMartin Storsjö2014-01-07
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* Rename CONFIG_FFT_FLOAT ---> FFT_FLOATDiego Biurrun2014-01-06
| | | | | The define does not originate from configure, so it should not have a name that is CONFIG_-prefixed.
* h264: do not use 422 functions for monochromeAnton Khirnov2014-01-06
| | | | | | | Fixes invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org

* arm: h264chroma: Do not compile h264_chroma_mc* dependent on h264 decoderDiego Biurrun2013-08-23
| | | | | The functions are used by all codecs that enable the h264chroma component and the file is already compiled conditional on h264chroma being enabled.
* vp56: Mark VP6-only optimizations as such.Diego Biurrun2013-08-23
| | | | | Most of our VP56 optimizations are VP6-only and will stay that way. So avoid compiling them for VP5-only builds.

* arm: Comment out unused labels in simple_idct_armMartin Storsjö2013-07-24
| | | | | | | | | | | | | | | | | When building for iOS in thumb mode, gas-preprocessor.pl doesn't mark unused labels as thumb functions (as it does for other local labels, where it can figure out that they are functions due to being referenced in branch instructions). This leads to linker warnings for some of those local labels, such as: ld: warning: ARM function not 4-byte aligned: __a_evaluation from libavcodec/libavcodec.a(simple_idct_arm.o) Therefore, comment them out since they don't have any function. They do still have a value in documenting key points in the assembly source though. Signed-off-by: Martin Storsjö <martin@martin.st>

* vp3: Use full transpose for all IDCTsRonald S. Bultje2013-04-15
| | | | | | | | | | | This way, the special IDCT permutations are no longer needed. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Also remove the unused type == 0 cases from the plain C version of the idct. Signed-off-by: Martin Storsjö <martin@martin.st>
