Copyright (c) 2016 Google, Inc. Copyright (c) 2016 Google, Inc.

To enable SSE support in libpng, apply intel_sse.patch in your build
directory, before running "configure". If you prefer, manually edit
configure.ac and Makefile.am, following the instructions below, then
then follow the instructions in section II of INSTALL in the main libpng
directory.
Then configure libpng with -DPNG_INTEL_SSE in CPPFLAGS. If you only
want to optimize reading 4bpp images, also use -DPNG_NO_INTEL_SSE_3BPP.
If you have moved intel_init.c and filter_sse2_intrinsics.c to a different If you have moved intel_init.c and filter_sse2_intrinsics.c to a different
directory, be sure to update the '#include "../../pngpriv.h"' line in both directory, be sure to update the '#include "../../pngpriv.h"' line in both

with respect to the new location of those files. with respect to the new location of those files.
If you are using a custom makefile instead of a configure-generated To enable SSE support in libpng, follow the instructions in I, II, or III,
makefile, you will have to update it manually to include contrib/intel/*.c below:
and to define PNG_INTEL_SSE and possibly PNG_NO_INTEL_SSE_3BPP.
I. Using patched "configure" scripts:
First, apply intel_sse.patch in your build directory.
patch -i contrib/intel/intel_sse.patch -p1
Then, if you are not building in a new GIT clone, e.g., in a tar
distribution, remove any existing pre-built configure scripts:
./configure --enable-maintainer-mode
make maintainer-clean
./autogen.sh --maintainer --clean
Finally, configure libpng with -DPNG_INTEL_SSE in CPPFLAGS. If you only
want to optimize reading 4bpp images, also use -DPNG_NO_INTEL_SSE_3BPP:
./autogen.sh --maintainer
CPPFLAGS="-DPNG_INTEL_SSE -DPNG_NO_INTEL_SSE_3BPP" ./configure [options]
make
II. Using a custom makefile:
If you are using a custom makefile makefile, you will have to update it
manually to include contrib/intel/*.o in the dependencies, and to define
PNG_INTEL_SSE and possibly PNG_NO_INTEL_SSE_3BPP.
III. Using manually updated "configure" scripts:
If you prefer, manually edit configure.ac and Makefile.am, following the
instructions below, then follow the instructions in section II of INSTALL
in the main libpng directory, then configure libpng with -DPNG_INTEL_SSE
in CPPFLAGS. If you only want to optimize reading 4bpp images, also use
-DPNG_NO_INTEL_SSE_3BPP.
