703c69de81 codec: add a new macro for unused functions 
Variables used only for tracing logs can trigger
-Werror=unusef-variable when tracing is disabled.
This macro helps to silent gcc in those casesWIP

72da7f8711 Remove an unused error code 
I don't see this error code being useful - working slowly hardly
would be a reason for the library to return and fail to do what
it was asked to do, so normal functions would never actually return
this code.

3cf52554f7 Backup/restore the xmm6-xmm15 SSE registers within asm functions on win64 
According to the Win64 ABI, these registers need to be preserved,
and compilers are allowed to rely on their content to stay
available - not only for float usage but for any usage, anywhere,
in the calling C++ code.

This adds a macro which pushes the clobbered registers onto the
stack if targeting win64 (and a matching one which restores them).
The parameter to the macro is the number of xmm registers used
(e.g. if using xmm0 - xmm7, the parameter is 8), or in other
words, the number of the highest xmm register used plus one.

This is similar to how the same issue is handled for the NEON
registers q4-q7 with the vpush instruction, except that they needed
to be preserved on all platforms, not only on one particular platform.

This allows removing the XMMREG_PROTECT_* hacks, which can
easily fail if the compiler chooses to use the callee saved
xmm registers in an unexpected spot.

966cc97496 Remove a dubious/unnecessary workaround for an issue in a nonstandard toolchain 
There's no requirement to work with the Intel NDK. The NDK build
files don't even need to create any cpufeatures subdirectory since
all of the cpufeatures library is handled within the normal build
system. Finally, the encoder makefile tried to create a directory
for "welsdecdemo", not anything for "welsencdemo".

Thus, if this really was necessary, it would already have been noticed
that it missed an entry for "welsencdemo". Therefore, remove this
hack/workaround.

c011890764 Push clobbered neon registers on the stack 
According to the calling convention, the registers q4-q7 should be
preserved by functions. The caller (generated by the compiler) could
be using those registers anywhere for any intermediate data.

Functions that use more than 12 of the qX registers must push
the clobbered registers on the stack in order to be able to restore them
afterwards.

In functions that don't use all 16 registers, but clobber some of
the callee saved registers q4-q7, one or more of them are remapped
to reduce the number of registers that have to be saved/restored.

This incurs a very small (around 0.5%) slowdown in the decoder and
encoder.

811c647c0e Remap registers to avoid clobbering the neon registers q4-q7 
According to the calling convention, the registers q4-q7 should be
preserved by functions. The caller (generated by the compiler) could
be using those registers anywhere for any intermediate data.

Functions that use 12 or less of the qX registers can avoid
violating the calling convention by simply using other registers instead
of the callee saved registers q4-q7.

This change only remaps the registers used within functions - therefore
this does not affect performance at all. E.g. in functions using
registers q0-q7, we now use q0-q3 and q8-q11 instead.

5b8ee37162 Merge WelsThreadDestroy into WelsThreadJoin 
Now calling WelsThreadJoin is enough to finish and clean up
the thread on all platforms.

This unifies the thread cleanup code between windows and unix.

Now all of the threading code should use the exact same codepaths
between windows and unix.

11bdebb12c Explicitly enable the UAL syntax when using gnu tools 
Arm assembly has got two variants of the syntax, the old legacy
syntax, and the new modern UAL (unified assembly language) syntax.

Most arm assembly is the same in the both syntaxes, but some
uncommon cases change the order of suffixes - the "subscs"
instruction would be written "subcss" in the old syntax.

The apple tools default to UAL, while the GNU tools (e.g. in
android) require you to specify ".syntax unified" to enable the
new syntax. When enabling the new syntax with the GNU tools, some
cases of "sub r0, r1, lsl #1" needs to be written explicitly as
"sub r0, r0, r1, lsl #1", handled in the previous commit.

This allows using the same, modern syntax for things like subscs,
without needing to have two alternate forms of writing it.

8ba79262bf Rename a function to avoid conflicts between almost duplicate neon functions 
There's a different version of the same function in the encoder,
but they're not identical - the encoder version has got stricter
alignment requirements.

If someone can confirm that it is ok to use the function from the
encoder, pixel_sad_neon.S in processing could be deleted, and the
encoder version moved to codec/common instead.

636df2bebb Use WelsMultipleEventsWaitSingleBlocking within the worker thread on unix as well

events, and later allowing using the encode exit event on unix instead

801da26d1d Use WelsMultipleEventsWaitSingleBlocking with a master event for waiting on finished threads 
This allows using the same codepath for both unix and windows
for distributing new slices to code to threads.

This also improves the performance on unix - instead of waiting
for all the current threads to finish their current slice
before handing out a new slice to each of them (where the threads
that finish first will just wait instead of immediately getting
a new slice to work on), we now use the same logic as on windows.

In one setup, it improves the performance of encoding from ~920 fps
to ~950 fps, and in another setup it goes from ~390 fps to ~660 fps.
(These tests were done with the SM_ROWMB_SLICE mode, which
heavily exercises the code for distributing new slices to the
worker threads.)

The extra WelsEventSignal call on windows where it isn't strictly
necessary doesn't incur any measurable slowdown, so it is kept
without any extra ifdefs to keep the code more readable and unified.

276b585f03 Use the cpu-features NDK library for detecting the number of cores in WelsThreadLib 
On arm, the exact same detection is done in WelsCPUFeatureDetect,
but in the x86 version of that function we use x86 cpuid for getting
the core count, and this is not available on all processors. For the
case when cpuid can't tell the core count, use the NDK function as
higher level API.

The thread lib itself doesn't build properly on android yet, but will
do so soon.

d0a81355b0 Add support for using a separate "master event" in WelsMultipleEventsWait*Blocking 
This allows making the WelsMultipleEventsWaitSingleBlocking
function work properly in unix, without polling. If a master
event is provided, the function first waits for a signal on
that event - once such a signal is received, it is assumed that
one of the individual events in the list have been signalled as
well. Then the function can proceed to check each of the semaphores
in the list using sem_trywait to find the first one of them that
has been signalled. Assuming that the master event is signalled
in pair with the other events, one of the sem_trywait calls
should succeed.

The same master event is also used in
WelsMultipleEventsWaitAllBlocking, to keep the semaphore values
in sync across calls to the both functions.

de32455d87 Remove the timeout parameter from WelsMultipleEventsWaitSingleBlocking
