A command line tool to print out the chunk level structure of
WebP files along with basic integrity checks.
BUG=webp:330
Change-Id: Ic69f646f649abb655b1854621d99afedeed158d7
Uses WebPToSDL() generic function defined in vwebp_sdl.[ch].
This function is not included in the libextras library, because it
would bring in an SDL dependency. Probably too heavy for now.
WebPToSDL() is separate, because it will be called used by the javascript
version of libwebp (through emscripten build rules)

use a compile check on a separate file to avoid assuming using
arm_neon.h is safe to use without flags when just the file itself is
self-contained with GCC target pragmas.

(cherry picked from commit 0104d730bf)

BUG=webp:313
Change-Id: I48f92ae3e6e4a9468ea5b937c80a89ee40b2dcfd
reserve src/ for the code of the main libraries: libwebp, libwebpdemux
and libwebpmux
+ demote this library to internal only; i.e., don't install the header +
lib with make install
Change-Id: I8c9844db8f494be0fa0a2549a5b75b5cebcf666d
configure gets 2 new options:
--enable-neon / --enable-neon-rtcd
the NEON modules are split to their own convenience lib and built with
auto-detected flags if none are given via CFLAGS.
the /proc/cpuinfo check will only be used for armv7 targets whose
toolchain does not enable NEON by default or didn't have NEON forced by
the CFLAGS from the environment.
Change-Id: I2755bc1d065d5d6ee6143b44978c2082f8bef1c5
TEST_AND_ADD_CFLAGS tests flags independently from AM_CFLAGS. The lack
of -Wformat may cause -Wformat-* checks to fail (gcc 4.9), though in the
end they would have succeeded with -Wall present.

and make it the default if available. this limits symbol visibility to
those marked with WEBP_EXTERN.

add -flax-vector-conversions as a workaround when building the
intrinsics files. this was made available in 4.3.x, but may have been
backported. issue observed with:
cc (GCC) 4.2.1 20070831 patched [FreeBSD] (9.3).

+ jenkins fixes for native config (library order)
+ add a missing -lm
+ replace log10 by log, just in case
+ partially reverted configure.ac to remove the C++ part

It can be used to test if given pair of animated images (GIF and/or
WebP) are identical in terms of pixel match and other animation
properties.

Visible speed-up, thanks to pshufb and pabsw and psignw use.
had to tweak configure.ac to make "smmintri.h" presence correctly
detected (we need to set the CPPFLAGS instead of the CFLAGS!)
Change-Id: I2ab99e16a27a64fdf1f09b2b4e30a5e74ccca080
fixes thread support detection in e.g., cross-compiles/mingw installs
without libpthread, the behavior is unchanged in mingw installs with
libpthread. in the latter case although libpthread is detected the
windows api (_beginthreadex) path is being used.
Change-Id: Ie5f39f15f380731a1006a2497496d627f08fa103
defines HAVE_BUILTIN_BSWAP16/32/64
updated endian_inl.h to have a non-configure fallback for gcc and clang
BSwap16() now uses __builtin_bswap16 if available
Change-Id: Ia04ee07b39303c4b247df96d84f298fb8a81f389
possibly other cross-compiles; avoids misusing -mavx2/-msse2 in these
cases by checking the usability of the associated intrinsics header
files.
iosbuild.sh has been broken since at least:
