DRC 5a3b4fed 2016-01-06T19:17:54 Regression: Allow co-install of 32-bit/64-bit RPMs Fix a regression introduced in 1.4.1 that prevented 32-bit and 64-bit libjpeg-turbo RPMs from being installed simultaneously on recent Red Hat/Fedora distributions. This was due to the addition of the SIZEOF_SIZE_T macro in jconfig.h, which allows the Huffman codec to determine the word size at compile time. Since that macro differs between 32-bit and 64-bit builds, this caused a conflict between the i386 and x86_64 RPMs (any differing files, other than executables, are not allowed when 32-bit and 64-bit RPMs are installed simultaneously.) Since the macro is used only internally, it has been moved into jconfigint.h.

DRC 3ebcc320 2015-05-15T19:09:44 __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.) git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.4.x@1550 632fc199-4ca6-4c93-a231-07263d6284db

DRC bc56b754 2014-05-16T10:43:44 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. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1308 632fc199-4ca6-4c93-a231-07263d6284db
DRC 52ded876 2014-05-15T20:30:16 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.) git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1307 632fc199-4ca6-4c93-a231-07263d6284db
DRC b7753510 2014-05-11T09:36:25 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.) git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.3.x@1285 632fc199-4ca6-4c93-a231-07263d6284db

DRC bc51580f 2011-04-18T06:52:07 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 git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@590 632fc199-4ca6-4c93-a231-07263d6284db
