| Description: |
| This consists of the components: |
| * A partial copy of libjpeg-turbo 1.3.1 (r1219); |
| * Revision r1188 cherry-picked from upstream trunk into config.h; |
| * Revision r1220 cherry-picked from upstream trunk into jchuff.c; |
| * Revisions r1108, r1109, r1333, r1375, r1386, r1389 and r1390 cherry-picked |
| from upstream trunk for Arm64; |
| * A build file (libjpeg.gyp), and; |
| * Patched header files used by Chromium. |
| |
| This libjpeg-turbo can replace our libjpeg-6b without any modifications in the |
| Chromium code. |
| |
| Same as our copy of libjpeg-6b, this libjpeg-turbo also added a new file |
| jpeglibmangler.h and included it from jpeglib.h that changes the names of all |
| externally visible functions to chromium_* so that we can avoid conflicts that |
| arise when system libraries attempt to use our libjpeg. Also, we applied the |
| following changes which are not merged to upstream: |
| |
| * Added the 'private_extern' flags on Mac (or the 'hidden' flags on Linux) to |
| all the global symbols in '.asm' files to prevent making them external ones. |
| * Supported motion-JPEG frames that do not have DHT markers. |
| * Removed .func / .endfunc lines from arm assembly |
| ( https://sourceforge.net/p/libjpeg-turbo/bugs/72/ , landed at |
| https://sourceforge.net/p/libjpeg-turbo/code/1375 ). |
| * Fix libjpeg_turbo svn r64 libjpeg6b compat issue: make the fast path Huffman |
| decoder fallback to slow decoding if the Huffman decoding bit sentinel > 16, |
| this to match the exact behavior of jpeg_huff_decode(). |

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