generic version got fixed, but not the arm version. fixes:
vp8/encoder/arm/mcomp_arm.c: In function 'vp8_full_search_sadx3':
vp8/encoder/arm/mcomp_arm.c:1208: warning: pointer targets in passing
argument 5 of 'fn_ptr->sdx3f' differ in signedness

argument is of type 'int *'

and another unsigned change to keep the files similar

vp8_diamond_search_sadx4 isn't used in arm because there is no
corrosponding sdx4df as in x86. rather than keep it in sync with
../mcomp.c, delete it

vp8_hex_search had the original, more readable/understandable code if`d
out. it's also available in ../mcomp.c, so remove the dead copy

In order to know if all 4/8 neighbor points are within the bounds,
4 bounds checking are enough instead of checking 4 bounds for
each points (16/32 checkings). This improvement reduces cost of
vp8_diamond_search_sadx4() by 30%, and gives encoder a 1.5%
performance gain (test options: 1 pass, good, speed=4).

This patch moves the scattered updates to the mb skip state
(mode_info_context->mbmi.mb_skip_coeff) to vp8_tokenize_mb. Recent
changes to the quantizer exposed a bug where if a macroblock
could be coded as a skip but isn't, the encoder would run the
loopfilter but the decoder wouldn't, causing a reference buffer
mismatch.

The loopfilter is controlled by a flag called dc_diff. The decoder
looks at the number of decoded coefficients when setting this flag.
The encoder sets this flag based on the skip state, since any
skippable macroblock should be transmitted as a skip. The coefficient
optimization pass (vp8_optimize_b()) could change the coefficients
such that a block that was not a skip becomes one. The encoder was
not updating the skip state in this situation for intra coded blocks.

The underlying issue predates it, but this bug was recently triggered
by enabling trellis quantization on the Y2 block in commit dcd29e36,
and by changing the quantizer range control in commit 305be4e4.

These functions should never change their input, and there's no
 reason not to declare that.
This allows them to be passed static const data.

There is currently no inexact version of this function, so do not
 even compile it without EXACT_QUANT.
This will prevent someone from inadvertently trying to use it without
 the proper EXACT_QUANT setup.

This is just eliminating some cruft.
Although a number of variables are declared only when INTRARDOPT
 is defined, they are used elsewhere without that protection, and
 no longer just for intra RDO.
The intra_rd_opt flag was hard-coded to 1 and never checked.

An earlier automatic transform changed eg '\nOptions' to '\n_options'

As the zbin and rounding constants are normalized, rounding effectively
does the zbinning, therefore the zbin operation can be removed. In
addition, the memset on the two arrays are no longer necessary.

yasm has to be preferred as currently nasm produces marginally less
efficient code (longer opcodes). Filed for nasm as:
https://sourceforge.net/tracker/?func=detail&atid=106208&aid=3037462&group_id=6208

OTOH package should be built always the same, no matter which additional
packages are / are not present on the system. As the package should be
built with nasm (as yasm may not be available) we should not use yasm
even if it is possibly available.

nasm >= approx. 2.09 is required for the nasm compilation as the former
versions had a section alignment bug.

Provide nasm compatibility. No binary change by this patch with yasm on
{x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on
{x86_64,i686}-fedora13-linux-gnu have been checked as safe.

nasm just does not accept any size parameter for movhps:
1.asm:2: error: mismatch in operand sizes

Some parts of libvpx already use MMWORD for movhps and MMWORD is
defined-out so it is compatible both with yasm and nasm.

nasm requires the instruction length (movd/movq) to match to its
parameters. I find it more clear to really use 64bit instructions when
we use 64bit registers in the assembly.

This code adjust the impact of the amount and speed of motion
on GF and KF boost.

Sections with lots of slow motion will tend to have a
somewhat bigger boost and sections with fast motion may
have less.

There is a knock on effect to the selection of the active
quantizer range.

This will likely require further tuning but helps with a couple
of particularly bad edge cases.

Experimented with different value for Y2_RD_MULT ranging f[1, 32],

Like the ARMv6 code, these functions were accessing values below
 the stack pointer, which can be corrupted by signal delivery at
 any time.

Modified the range checking of parameters used in the
AltRef temporal filter (arnr-max-frames, arnr-strength,
arnr-type) and default values for each of them.
