Jing Yu	311a953c76	avcodec/ppc: fix broken build when compiling libavcodec with LLVM on PPC backend This commit fixes a broken build when compiling libavcodec with LLVM compiler. These assembly files use non-standard format that is only supported by GCC compiler. It would be nice to use a common standard format. With this patch, both GCC and LLVM can build and generate the same objects. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Ganesh Ajjanagadde	789ef087c6	avcodec/ppc/fdctdsp: use more accurate constants Whoever wrote this stuff had a pretty bad libm - digits differ pretty quickly. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Ganesh Ajjanagadde	61a1ca13ea	avcodec/ppc/fdctdsp: use M_SQRT2 instead of ad-hoc SQRT2 This actually fixes an incorrect float literal. It is believed by examining the precision that the literals were all pre-computed as floats, resulting in this needless loss of precision. There is no benefit to keeping such reduced precision: 1. These constants are used for static array computation, hence compile-time. 2. They will be treated as doubles anyway, since f specifier was not present.

Christophe Gisquet	562ba4a827	blockdsp: remove high bitdepth parameter It is only (mis-)used to set the dsp fucntions clear_block(s). But these functions always work on 16bits-wide elements, which make the parameter useless and actually harmful, as it causes all content on more than 8-bits to not use accelerated functions.

Rong Yan	a2cd07d22a	avcodec/ppc/h264dsp: POWER LE support in h264_idct_dc_add_internal() fix vec_lvsl bug We got defective video when use GCC 4.9.2 instead of GCC 4.9.1 to compile FFMEPG. And further found that GCC 4.8 and 4.9 need patch to fix the lvsl/lvsr bug on POWER LE, and GCC 5.1 contains the correct code since its release. The message on gcc-patches requesting approval for lvsl/lvsr patch is at https://gcc.gnu.org/ml/gcc-patches/2014-10/msg00228.html. The fixed code avoids using lvsl and will not depends on GCC version, also it uses less instructions on POWER LE. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
