arm: Implement a NEON version of 422 h264_h_loop_filter_chroma
Merged-by: James Almer <jamrial@gmail.com>
|

Previously, the 420 version was used even for 422.
This fixes occasional checkasm failures.

This makes it similar to put_epel16_v6, and gives a 10-25%

When targeting darwin, clang requires commas between arguments,
while the no-comma form is allowed for other targets.
Since Xcode 9.3, the bundled clang supports altmacro and doesn't
require using gas-preprocessor any longer.

Clang supports the macro expansion counter (used for making unique
labels within macro expansions), but not when targeting darwin.
Convert uses of the counter into normal local labels, as used
elsewhere.

Compilation error "out of range" fixed for armeabi-v7a. Compilation failed
trying to build libvlc.aar for ARM7 android on ubuntu 16.04 host. Error
messages is "Offset out of range". The reason of the error is assembler LDR
directives in function "ff_hevc_transform_luma_4x4_neon_8" need local storage
in range <1k, but no such storage provided.

In binutils 2.29, the behavior of the ADR instruction changed so that 1 is
added to the address of a Thumb function (previously nothing was added). This
allows the loaded address to be passed to a BLX instruction and the correct
mode change will occur.
See: https://sourceware.org/bugzilla/show_bug.cgi?id=21458
By using adr with a label that isn't annotated as a thumb function,
we avoid the new behaviour in binutils 2.29 and get the same behaviour
as in prior releases, and as in other assemblers (ms armasm.exe,
clang's built in assembler) - an idea that Janne Grunau came up with.

It is redundant with costable. The first half of sintable is
identical with the second half of costable. The second half
of sintable is negative value of the first half of sintable.
The computation is changed to handle sign of sin values, in
C code and ARM assembly code.

The code originally pre-multiply by 2 the steps, causing the running sum
of the h factors to drift away due to the lack of precision. It quickly
causes an inaccuracy > 0.01.
I tried diverse approaches such as multiply by 2.0 (instead of adding
the value itself) without success.
I'm unable to bench the impact of this change, feel free to compare.
This commit fixes the incoming aacpsdsp tests.

clang now (in the upcoming 5.0 version) is capable of building our
arm assembly without relying on gas-preprocessor, although clang/LLVM
doesn't support .dn register aliases.
The VC1 MC assembly was only built and used if the chosen assembler
supported the .dn directives though. This was supported as long as
gas-preprocessor was used.
This means that VC1 decoding got a speed regression on clang 5.0,
unless the user manually chose using gas-preprocessor again.
By avoiding using the .dn register aliases, we can build the VC1 MC
assembly with the latest clang version.
Support for the .dn/.qn directives in clang/LLVM isn't actively planned,
see https://bugs.llvm.org/show_bug.cgi?id=18199.
This partially reverts 896a5bff64264f4d01ed98eacc97a67260c1e17e.

Instead, hardcode the use of the _arm implementation of add_pixels,
and use the C version for put_pixels (as no arm-optimized version
exists). Since there's separate implementations of idct{,_put,_add}
for neon, this has no practical impact on performance.
|
|
This allows vp9dsp.h to only include the VP9 types header, and not the
decoder skeleton interface which is for hardware decoders (dxva2/vaapi).
|
|
The advantage here is that the internal software decoder interface is
not exposed to the DSP functions or the hardware accelerations.
|
|
The main hevcdsp.c file calls this init function if HAVE_ARM is set,
regardless of whether neon support is available or not.
This fixes builds where neon isn't supported by the build tools at all.
