2020-06-29Add input JPEG images for djpeg and jpegtran testsJonathan Wright
Upstream unit tests use the output of cjpeg tests as input for djpeg and jpegtran tests. To avoid the coupling of compression and decompression unit tests, this commit adds the input JPEG images for the djpeg and jpegtran unit tests to the testimages directory. These images are generated from the original images in the testimages directory and are distributed under the same license. Bug: 993876 Change-Id: I1c08432f8891f71d081df284ff83bbc021d8cb72
2020-06-24Refactor jpegtran.c to provide test interfaceJonathan Wright
jpegtran.c contains a standalone program to transcode JPEG images. One use of jpegtran is to generate input for libjpeg-turbo unit tests. This commit refactors jpegtran.c to provide an interface to run the jpegtran code programmatically. A gtest wrapper containing JPEG transcoding unit tests will be introduced in a subsequent commit.

2020-06-23Refactor cjpeg.c to provide test interfaceJonathan Wright
cjpeg.c contains a standalone program to encode JPEG images. One use of cjpeg is to generate input for libjpeg-turbo unit tests. This commit refactors cjpeg.c to provide an interface to run the cjpeg code programmatically. A gtest wrapper containing JPEG compression unit tests will be introduced in a subsequent commit.

2020-06-23Write tjunittest output files to sdcard on AndroidJonathan Wright
For tjunittest tests to complete successfully, they need to write output image files to disk. On Android, only some parts of the filesystem are write enabled. This commit sets the write path to /sdcard (which is write enabled) when building libjpeg_turbo_unittests for Android. Bug: 993876 Change-Id: I87bb942311610bff089488d3e4d14dac523bf8aa
2020-06-19Move tbench logs from stdout to stderrJonathan Wright

2020-06-19Add gtest wrapper for tjbench testsJonathan Wright

2020-06-16Reinstate upstream test image data filesJonathan Wright
These images and data will be used by tests added in subsequent commits. Bug: 993876 Change-Id: Ie4612eea6d0d3804789e1ad1eb9242f3c4cc290b
2020-06-16Refactor tjbench.c to provide test interfaceJonathan Wright
tjbench.c contains a program to benchmark encoding and decoding of JPEG images. As such, the code in tjbench.c was designed to run as a stanalone binary. As well as benchmarking code, tjbench is used to produce image data for unit test input. This commit refactors tjbench.c to provide an interface to run the tjbench code programmatically. A gtest wrapper containing unit tests will be introduced in a subsequent commit. All other global symbols in tjbench.c are marked as 'static' to prevent symbol collision.

2020-06-16Add gtest wrapper for tjunittestsJonathan Wright
Adds a gtest wrapper and GN build configuration for the unit tests in tjunittest.c. Bug: 993876 Change-Id: Ic33c6930de0e0005aebb70cb358823640a35c8b7
2020-06-16Refactor tjunittest.c to provide test interfaceJonathan Wright
tjunittest.c contains unit tests for the TurboJPEG API (which in turn test the underlying libjpeg-turbo code.) These tests were designed to run as a standalone binary. This commit refactors tjunittest.c to provide an interface to run all unit tests individually. This is the first step towards running all tests through the gtest framework. The following files are also reinstated from the upstream libjpeg-turbo project as the tests in tjunittest.c rely on an MD5 checksum: * md5/md5.h * md5/md5.c * md5/md5hl.c Bug: 993876 Change-Id: I6380a8f0ca5db02b40a1235e379cb1e5134becca

2020-03-30Fix Mac builds of libjpeg-turboChris Blume
Mac builds were failing because they were exporting symbols and we have tooling to make sure we do not accidentally export symbols. The cause of this was a switch from YASM to NASM and libjpeg-turbo not adding :private_extern to Mach-O symbols when using NASM. The fix for this already landed upstream so I am cherrypicking the patch [1].

2019-12-11Precompute DCT block output pointers in IDCT functionsJonathan Wright
Computes the output pointer values for storing DCT blocks ahead of time so the compiler knows that the storage locations for each row do not overlap and are not changed by storing each successive row of coefficients. The base pointer can be loaded once, rather than being reloaded after storing each row of the DCT block - breaking a memory dependency chain and increasing overall decode performance.
