vp9_short_idct10_16x16_add is used to handle the block that only have valid data
at top left 4x4 block. All the other datas are 0. So we could cut many
unnecessary calculations in order to save instructions.

It is possible to have invalid scale factors and not access them
during decoding. Error is reported if we really try to use invalid scale
factors.

Adding set_contexts contexts function and call it instead of
set_contexts_on_border. Calling txfrm_block_to_raster_xy to get aoff and
loff.
Change-Id: I41897e344afd2cae1f923f4fdbe63daccf6fe80e
Moving foreach_predicted_block_in_plane function to vp9_reconinter.c
because there is only one usage.

Updating implementation of vp9_get_pred_context_single_ref_p2 using
has_second_ref function to make code easier to read.

As the pixel values beyond image border are duplicates of pixels
on edge, the change limits the mv search range, any mv beyond
the limits no longer produce new/different prediction values
as entire block with pixels used for subpel interpolation are
outside image border.

Updating all foreach_transformed_block_visitor functions to work with
plane block size instead of general block. Removing a lot of duplicated
code.
Change-Id: I6a9069e27528c611f5a648e1da0c5a5fd17f1bb4
This change set is intermediate. The next one will remove all repetitive
plane_bsize calculations, because it will be passed as argument to
foreach_transformed_block_visitor.

The intent was to initialize the deltas for the
segment to the computed value, irrespective of mode
and reference frame if (mode_ref_delta_enabled == 0).
(In response to bug posted by Manjit Hota to codec-devel
and webm-discuss lists)
Change-Id: I10435cb63d0f88359bb4c14f22181878a1988e72
When the frame size changes the last frame segment map must
be resized to match and initialized to 0.

VP9_COMMON is the right place to segmentatation struct because it has
global segmentation parameters, not something specific to macroblock
processing.

This commit unifies the rate-distortion cost calculation process of
luma and chroma components. It allows early termination to be enabled
later in the rd search loop of chroma components, in consistent with
luma pixels.
Change-Id: I2e52a7c6496176bf2a5e3ef338d34ceb8aad9b3d
Making foreach_transformed_block_in_plane more clear (it's not finished
yet). Using explicit tx_size variable consistently instead of
(ss_txfrm_size / 2) or (ss_txfrm_size >> 1) expression.
Change-Id: I1b9bba2c0a9f817fca72c88324bbe6004766fb7d
The macro block mode info context originally contained an
entry for each 16x16 macroblock. In VP9 each entry refers
to an 8x8 region not a macro block, so the naming is misleading.
This first stage clean up changes the names of 3 entries in the
structure to remove the mb_ prefix.
TODO clean up the nomenclature more widely in respect of
mbmi and bmi.

Enable SSE2 implementation of high precision 32x32 forward DCT. The
intermediate stacks are of 32-bits. The run-time goes down from
32126 cycles to 13442 cycles.
Change-Id: Ib5ccafe3176c65bd6f2dbdef790bd47bbc880e56
Adding function build_inter_predictors_for_planes to build inter
predictors for specified planes. This function allows to remove
condition "#if CONFIG_ALPHA" and use MAX_MB_PLANE for general case.
Renaming 'which_mv' local var to 'ref', and 'weight' argument to 'ref'.

Invert loops to operate vertically in the inner loop. This allows
removing redundant loads.
Also add preloading of data.
Change-Id: I4fa85c0ab1735bcb1dd6ea58937efac949172bdc
Each iteration of the horizontal loop reuses 7 of the 11 source
values. Loading only the 4 new values saves some time.
Also add preload for source data.
Overall 4% faster on Chromebook.

Loop filter configuration doesn't belong to macroblock, so moving it from
MACROBLOCKD to VP9_COMMON. Also moving the declaration of loopfilter struct
from vp9_blockd.h to vp9_loopfilter.h.

The memset sets 16 bytes rather than the correct size of the
final array dimension (MAX_MODE_LF_DELTAS).
(In response to bug posted by Manjit Hota to codec-devel
and webm-discuss lists)
Change-Id: I8980f5aa71ddc9d7ef57c5b4700bc28ddf8651c7
Using block width and block height instead of their logarithms. Using
SUBPEL_BITS and SUBPEL_SHIFTS constants instead of magic numbers.
Change-Id: I4e10e93c907c8a5e1cb27dfe74d1fcdcc4995448
Removing the old one bsize_from_dim_lookup. Now we have a way to determine
block size for plane using its subsampling values (ss_size_lookup). And
then we can find the number of pixels in the block (num_pels_log2_lookup).
Change-Id: I6fc981da2ae093de81741d3d78eaefed11015db9
Functions scale_mv_q4 and scale_mv_q3_to_q4 were almost identical except
q3->q4 conversion in scale_mv_q3_to_q4. Now q3->q4 conversion happens
directly in vp9_build_inter_predictor.
Also adding useful constants: SUBPEL_BITS and SUBPEL_MASK.
Change-Id: Ia0a6ad2ac07c45fdf95a5139ece6286c035e9639
Enable use_x86inc as a commandline option. Fix Bug with sse2 when
x86inc is disabled. Adds Sad asm protection to x86inc protection

There was no benefit having this function. For example, inside
read_switchable_filter_type switchable filter context was calculated twice.
Change-Id: I79cd5bf95cbc0f6d8bf91a2e32289e01b18dcff1
Converting arguments of two functions (clamp_mv_ref, lower_mv_precision)
from int_mv* to MV*. Rewriting is_inside function to make it much shorter.
Change-Id: Ie4c4cf3eccd46707c7df099ec21fb1b61c72fc7a
Support enabling it or disabling it. Moved read out to configure.sh
so that its done once instead of in make and in config.

Currently the only threaded option for vp9 decode. Enabled when the
decoder config thread count is > 1.
Change-Id: I082959abac9e31aa4a38ed9fd68b94680e57f4df
This changeset allows to remove vp9_switchable_interp and
vp9_switchable_interp_map arrays and make code much clear. Actually we
still have to use these mapping but only inside read_interp_filter_type and
write_interp_filter_type functions.

Chromium does not support 32bit builds for Mac which use x86inc.asm.
Make the files which include it work if 64bit or not PIC enabled
starting with vp9_copy_sse2.asm
Consolidate these targets in vp9_rtcd_defs.sh

This is an attempt at rewriting vp9_find_mv_refs_idx. I believe that it gains
