2014-06-09fdct8x8_test: add missing avx2 functionsJames Zern
exercises the forward transforms no idct/iht implementations, so the c-code is used Change-Id: I76b4d1712f10225c1ffa5ffb0ed9a551e68b93b4
2014-06-03Re-enable unit test for SSSE3 forward 8x8 2D-DCTJingning Han

2014-06-03Rework unit test for 8x8 transformationJingning Han
This commit reworks the unit test for 8x8 forward/inverse transformation. It adds extreme input value test to detect overflow issues in the intermediate steps. It temporarily disables unit test for the SSSE3 version, which showed overflow failure in the new test conditions. Change-Id: I7caf10bba4b6db031add65d8c0eb99426b38aa42

2013-09-04Added ClearSystemState in a unit testYaowu Xu
There is another unit test that has been failing randomly on win32 build. Investigation has shown that the failure was caused by simd register state is not reset appropriately in the fdct8x8 test. This commit added ClearSystemState() in the teardown of this test, tests showed it resolved the random failure issue for win32 build. Related issue: https://code.google.com/p/webm/issues/detail?id=614 Change-Id: I9381d0c1a6f4b855ccaeef1aca8c417ac8c71ee2
2013-08-08fix unit test failure on win32 vs2008 buildYaowu Xu
The mix use of double type and simd code caused invalid values stored in double variables, further caused unit tests to fail. The failures were only observed on x86-win32-vs9 build with vs2008. Change-Id: If0131754a3bf217a5ace303b7963e8f5162c34b5
