9Description:
10This consists of the components:
11* A partial copy of libjpeg-turbo 1.3.1 (r1219);
12* Revision r1188 cherry-picked from upstream trunk into config.h;
13* Revision r1220 cherry-picked from upstream trunk into jchuff.c;
14* Revisions r1108, r1109, r1333, r1375, r1386, r1389 and r1390 cherry-picked
15  from upstream trunk for Arm64;
16* A build file (libjpeg.gyp), and;
17* Patched header files used by Chromium.
18
19This libjpeg-turbo can replace our libjpeg-6b without any modifications in the
20Chromium code.
21
22Same as our copy of libjpeg-6b, this libjpeg-turbo also added a new file
23jpeglibmangler.h and included it from jpeglib.h that changes the names of all
24externally visible functions to chromium_* so that we can avoid conflicts that
25arise when system libraries attempt to use our libjpeg. Also, we applied the
26following changes which are not merged to upstream:
27
28* Added the 'private_extern' flags on Mac (or the 'hidden' flags on Linux) to
29  all the global symbols in '.asm' files to prevent making them external ones.
30* Supported motion-JPEG frames that do not have DHT markers.
31* Removed .func / .endfunc lines from arm assembly
32  ( https://sourceforge.net/p/libjpeg-turbo/bugs/72/ , landed at
33  https://sourceforge.net/p/libjpeg-turbo/code/1375 ).

35The 'google.patch' file represents our changes from the original
36libjpeg-turbo-1.2.
