|
||||
Copyright (c) 2016 Google, Inc.
|
||||
Written by Mike Klein and Matt Sarett
|
||||
|
||||
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
|
||||
directory, be sure to update the '#include "../../pngpriv.h"' line in both
|
||||
files if necessary to point to the correct relative location of pngpriv.h
|
||||
with respect to the new location of those files.
|
||||
|
||||
If you are using a custom makefile instead of a configure-generated
|
||||
makefile, you will have to update it manually to include contrib/intel/*.c
|
||||
and to define PNG_INTEL_SSE and possibly PNG_NO_INTEL_SSE_3BPP.
|
||||
To enable SSE support in libpng, follow the instructions in I, II, or III,
|
||||
below:
|
||||
|
||||
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.
|
||||
|
||||
