6eb7d3798b5a79347c62825fc4c16f7ce673bdd0 16-Oct-2016 Alex Naidis <alex.naidis@linux.com> libjpeg-turbo: Upgrade to 1.5.1

The changes from 1.4.2 to 1.5.1 include
a big amount of fixes and huge performance improvements.
As highlights there is a full ARM 64-bit (ARMv8) NEON SIMD
implementation which improves compression of full-color JPEGs
by about 2-2.5x on average on Cortex-A53 and Cortex-A57 cores.
Also SIMD acceleration for Huffman encoding on NEON-capable
ARM 32-bit and 64-bit platforms was added.
Performance on x86/x86_64 was also improved by
adding better optimized SSE2 routines.

For the full changelog, please see the ChangeLog.md
file.

Partial decoding optimizations, the security fix
to adress b/27494207 and the fix for the AARCH64
conformance issueare present in the release.
The README.android file was edited to reflect this.

The configuration files were regenerated
and all Android specific changes were applied.

BUG:28268702

3ebcc3206f8aec0517a5840916d9249ca80f2b77 15-May-2015 DRC <dcommander@users.sourceforge.net> __WORDSIZE doesn't seem to be available on platforms other than Mac or Linux, and best practices are for user-level code not to rely on it anyhow, since it's meant to be an internal macro. Fortunately, autoconf already has a way of determining the word size at configure time, so it can be passed into the compiler. This should work on any platform and has been tested on all of the Un*x platforms we support (Linux, Mac, FreeBSD, Solaris.)

bc56b754e1a6a1db9ccadf64d6dda8a74140e1a3 16-May-2014 DRC <dcommander@users.sourceforge.net> Get rid of the HAVE_PROTOTYPES configuration option, as well as the related JMETHOD and JPP macros. libjpeg-turbo has never supported compilers that don't handle prototypes. Doing so requires ansi2knr, which isn't even supported in the IJG code anymore.

52ded8768022ab7e9e7670ddea0ba89e2890b837 15-May-2014 DRC <dcommander@users.sourceforge.net> Remove all of the NEED_SHORT_EXTERNAL_NAMES stuff. There is scant information available as to which linkers ever had a 15-character global symbol name limit. AFAICT, it might have been a VMS and/or a.out BSD thing, but none of those platforms have ever been supported by libjpeg-turbo (nor are such systems supported by other open source libraries of this nature.)

e5eaf37440b8e337ab150c017df7c03faf846c51 09-May-2014 DRC <dcommander@users.sourceforge.net> Convert tabs to spaces in the libjpeg code and the SIMD code (TurboJPEG retains the use of tabs for historical reasons. They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code. In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.)

bc51580f28c8ab2e45147a35aa3553f9de2c1c20 18-Apr-2011 DRC <dcommander@users.sourceforge.net> Re-factor and re-license under the libjpeg BSD-style license. Justification: the accelerated Huffman decoding optimizations in libjpeg-turbo were all developed by me as an independent developer. The structure of the inline Huffman decoding macros was originally borrowed from similar routines in the TurboJPEG/mediaLib codec, which is part of VirtualGL and TurboVNC. Thus, although the code for these macros was not copied verbatim, they were still thought to be a derivative work of TurboJPEG/mediaLib, and I assigned the copyright and license from TurboJPEG/mediaLib to them. I have re-written these routines from first principles by breaking down the libjpeg out-of-line routines. Although the new code bears algorithmic similarities to the TurboJPEG/mediaLib macros, it can now clearly be shown to be derived from the out-of-line routines and thus, in my opinion, it can no longer be considered a derivative of TurboJPEG/mediaLib. -- DRC
