* vorbisdsp: change block_size type from int to intptr_t.Ronald S. Bultje2013-01-20
| | | | This saves one instruction in the x86-64 assembly.
* ppc: vorbisdsp: Drop some unnecessary #includesDiego Biurrun2013-01-20
| | | | Also fixes compilation with AltiVec disabled.
* ppc: Include string.h for memsetMartin Storsjö2013-01-20
| | | | | | | This fixes build failures on ppc machines with a compiler that supports -Werror=implicit-function-declaration. Signed-off-by: Martin Storsjö <martin@martin.st>
* Move vorbis_inverse_coupling from dsputil to vorbisdspcontext.Ronald S. Bultje2013-01-19
| | | | | Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.
* vp3: integrate clear_blocks with idct of previous block.Ronald S. Bultje2013-01-19
| | | | | | | | | This is identical to what e.g. vp8 does, and prevents the function call overhead (plus dependency on dsputil for this particular function). Arm asm updated by Janne Grunau <janne-libav@jannau.net>. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* lavc: Move vector_fmul_window to AVFloatDSPContextJustin Ruggles2013-01-16
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* ppc: replace pointer casting with AV_COPY32Mans Rullgard2012-11-12
| | | | | | This removes warnings about strict aliasing violations. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: fix some unused variable warningsMans Rullgard2012-11-12
| | | | | | | The third argument of OP_U8_ALTIVEC is evaluated at most once so there is no need for a potentially unused temporary variable. Signed-off-by: Mans Rullgard <mans@mansr.com>
* build: non-x86: Only compile mpegvideo optimizations when necessaryDiego Biurrun2012-10-09
|
* ppc: fix Altivec build with old compilersMans Rullgard2012-10-08
| | | | | | | | | The vec_splat() intrinsic requires a constant argument for the element number, and the code relies on the compiler unrolling the loop to provide this. Manually unrolling the loop avoids this reliance and works with all compilers. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: fmtconvert: kill VLA in float_to_int16_interleave_altivec()Mans Rullgard2012-10-05

* ppc: fix build with altivec disabledMans Rullgard2012-07-18
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard2012-07-18
| | | | | | | | This moves all VP3-specific function pointers from dsputil to a new vp3dsp context. There is no reason to ever use the VP3 IDCT where an MPEG2 IDCT is expected or vice versa. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: Rename H.264 optimization template file for consistency.Diego Biurrun2012-06-12
|
* 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.
* ppc: Drop unused header regs.hDiego Biurrun2012-05-22
|
* ppc: add const where needed in scalarproduct_int16_altivec()Mans Rullgard2012-05-01
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: remove shift parameter from scalarproduct_int16_altivec()Mans Rullgard2012-05-01
| | | | | | | The shift parameter was removed from this interface in 7e1ce6a. This updates the Altivec implementation to match. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: dsputil: do unaligned block accesses correctlyMans Rullgard2012-05-01
| | | | | | | | | | | | To load unaligned vector data in the usual way, explicit vec_ld() should be used rather than dereferencing a pointer to a vector type. When the VSX extension is enabled, gcc may compile vector pointer dereferences using the VSX lxvw4x instruction instead of the lvx instruction typically used with Altivec/VMX. As the behaviour of these instructions with unaligned addresses differs, it is important that only lvx is used here. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ppc: drop unused function dct_quantize_altivec()Diego Biurrun2012-04-18
| | | | This also allows dropping some PPC-specific ugliness from dsputil.[ch].
* build: Consistently handle conditional compilation for all optimization OBJS.Diego Biurrun2012-04-12
|
* ppc: Add/remove a number of const qualifiers to fix related warnings.Diego Biurrun2012-04-09

* build: ppc: drop stray leftover backslashDiego Biurrun2012-03-26

* build: prettyprinting cosmeticsDiego Biurrun2012-03-26

* vp8: change int stride to ptrdiff_t stride.Ronald S. Bultje2012-03-02
| | | | | On 64bit platforms with 32bit int, this means we won't have to sign- extend the integer anymore.

* ppc: fix 32-bit PIC buildMans Rullgard2011-09-25
| | | | | | | | | | | On 32-bit ppc, the GOT pointer must be loaded manually. This adds a "get_got" assembler macro to compute the GOT address. The "movrel" macro is updated to take an additional parameter containing the GOT address since no register is reserved for this purpose on ppc32. These changes have no effect on ppc64 builds.

* ppc: remove redundant setting of Altivec IDCTMans Rullgard2011-07-27
| | | | | | | This is already set by dsputil_init_ppc() and is best done in only one place. Signed-off-by: Mans Rullgard <mans@mansr.com>
