2020-11-30Update libjpeg-turbo to v2.0.90 (2.1 beta1)Jonathan Wright
Update Chromium's copy of libjpeg-turbo to the latest upstream release (v2.0.90) and re-apply our local changes documented in README.chromium. Cherry-pick two additional changes from upstream to fix bugs found by fuzzers: 1) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/ccaba5d7894ecfb5a8f11e48d3f86e1f14d5a469 2) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/c7ca521bc85b57d41d3ad4963c13fc0100481084 Significant changes provided by this update: 1) A large performance boost to JPEG encoding due to an improved Huffman encoding implementation. 2) The complete removal of Arm Neon assembly code. This allows Arm's control-flow integrity security features (Armv8.3-A Pointer Authentication and Armv8.5-A Branch Target Identification) to be switched on with the appropriate compiler flags. Bug: 922430 Bug: b/135180511 Bug: 919548, 1145581 Change-Id: I319fcdc55b3fd5b219425c07a4e4a03587f4e06d
2019-03-01Update libjpeg-turbo to v2.0.1Chris Blume
In order to apply some performance updates from ARM, we need to update libjpeg-turbo. These performance updates have yielded a 50% speedup on some devices. This CL updates our copy of libjpeg-turbo to v2.0.1 and re-applies our local patches. This patch also deletes some extra files which were not being used locally. Update our local patch that was applied to fix http://crbug.com/398235 (https://codereview.appspot.com/229430043/). The original patch incorrectly removed "& 0xFF" which limited an array index to within that array's bounds (effectively reverting https://github.com/libjpeg-turbo/libjpeg-turbo/commit/fa1d18385d904d530b4aec83ab7757a33397de6e). Restore the mask, making the array access safe and fixing a graphical glitch which would otherwise be introduced by this change. Bug:922430 Change-Id: I3860fdb424deecf7a17818ed09a640e632e71f8d

(Duplicate of https://codereview.chromium.org/1939823002/ for landing.) TBR=noel@chromium.org,thakis@chromium.org BUG=608347, 398235, 591927 Review URL: https://codereview.chromium.org/1953443002 .
2015-08-06Add support for decoding to 565 to libjpeg_turboAaron Gable
It was submitted upstream at libjpeg_turbo as r1295 plus sundry fixes and SIMD optimizations (r1385, r1386, r1398, and r1402). Now cherry pick the change into third_party/libjpeg-turbo. At this time, this new capability is intended for Android devices, not Chrome, and should have no affect on JPEG decode behavior or perf of Chrome. BUG=516761 R=noel@chromium.org Review URL: https://codereview.chromium.org/1270213002 .
2015-08-03Add jpeg_skip_scanlines() API to libjpeg-turboAaron Gable
jpeg_skip_scanlines() API, a subset decoding optimization aimed at Android, was submitted upstream r1582. Pull that change, and sundry fixes, into the Chromium repo. This new API is targetted at Android devices, not Chrome, and should have no affect on JPEG decode behavior or perf of Chrome. Chrome uses suspending data source JPEG decoding, and the new API does not support such sources. Adding support for suspending data sources is a future TODO, should the need arise (refer to skbug.com/4036). BUG=515694 BUG=468914 patch from issue 256280043 at patchset 50001 (http://crrev.com/256280043#ps50001) R=agable@chromium.org Review URL: https://codereview.chromium.org/1271803002 .
2014-04-14Upgrade libjpeg_turbo to 1.3.1 (r1219)noel@chromium.org
Remove google.jdmarker.patch, since the fixes for CVE-2013-6629 and CVE-2013-6630 are upstream most everywhere now [1]. Version number to 1.3.1 (config.h, jconfig.h). README.chromium: "Fixed valgrind error" patch was upstreamed in r839 http://sourceforge.net/p/libjpeg-turbo/code/839. The r1188 cherry-pick was put in config.h, say that.

2012-01-18Update libjpeg-turbo to 1.2.0.hbono@chromium.org
This change applies the upstream changes from 1.1.90 to 1.2.0 (r733). BUG=none TEST=webkit layout_tests Review URL: https://chromiumcodereview.appspot.com/9232002 git-svn-id: http://src.chromium.org/svn/trunk/deps/third_party/libjpeg_turbo@118072 4ff67af0-8c30-449e-8e8b-ad334ec8d88c
2011-08-03Updates libjpeg-turbo to 1.1.90hbono@chromium.org
This change updates our copy of libjpeg-turbo to 1.1.90 (r677), which supports ARM NEON. BUG=none TEST=none Review URL: http://codereview.chromium.org/7554002 git-svn-id: http://src.chromium.org/svn/trunk/deps/third_party/libjpeg_turbo@95196 4ff67af0-8c30-449e-8e8b-ad334ec8d88c
2010-11-22Add build files for libjpeg-turbo.hbono@chromium.org
This change adds a GYP file, header files, and a README file used for building libjpeg-turbo. (This GYP file builds libjpeg-turbo only on Windows and Mac since Linux uses the system libjpeg.) BUG=48789 TEST=build libjpeg-turbo on Windows and Mac.

2010-11-01Adds libjpeg-turbo to our repository.hbono@chromium.org
This change lands the original libjpeg-turbo 1.0.1 (source files only) and NASM 2.09.2 (required for assembling .asm files on Windows) to "deps/third_party". I will send more changes to land its build files and patches to integrate it into Chrome.
