* x86: avcodec: Appropriately name files containing only init functionsDiego Biurrun2012-08-15

* x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.hMans Rullgard2012-08-09
| | | | | | | This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-03
| | | | | | | Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.
* ac3dsp: simplify x86 versions of ac3_max_msb_abs_int16Justin Ruggles2012-05-15
| | | | | | Simplifies the code by using cpuflags and a new macro. Also fixes the invalid use of the MMX2 pshufw operation in the MMX-only function.
* x86: Move some variable declarations below the appropriat #ifdef.Diego Biurrun2011-10-20
| | | | This avoids some unused variable warnings with YASM disabled.
* ac3dsp: add x86-optimized versions of ac3dsp.extract_exponents().Justin Ruggles2011-07-01

* ac3enc: modify mantissa bit counting to keep bap counts for all values of bapJustin Ruggles2011-05-28
| | | | | | instead of just 0 to 4. This does all the actual bit counting as a final step.

* ac3enc: add float_to_fixed24() with x86-optimized versions to AC3DSPContextJustin Ruggles2011-03-17
| | | | and use in scale_coefficients() for the floating-point AC-3 encoder.

* ac3enc: Add x86-optimized function to speed up log2_tab().Justin Ruggles2011-02-13
| | | | | | | AC3DSPContext.ac3_max_msb_abs_int16() finds the maximum MSB of the absolute value of each element in an array of int16_t. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
