  "message": "Optimizer optimization\n\nOptimizer::optimizeStoresInSingleBasicBlock() was taking an extremely long time due to\nlooping through all the instructions of a single basic block at every iteration. By\ncreating a much smaller list of only load/store operations the first time a single basic\nblock is encountered and reusing that list when the same block is encountered again,\nthis function now runs ~10X faster.\n\nIn my test case:\nout/Default/cc_unittests --gtest_filter\u003dImageBackgroundFilter.BackgroundFilterRotated_GL\nThe sw::optimize function went from taking almost 16s to roughly 1.5s.\n\nBug b/67872293\n\nChange-Id: I7e2e2aa8dc1bf2663988fb59b58d72d9ee986e36\nReviewed-on: https://swiftshader-review.googlesource.com/19408\nTested-by: Alexis Hétu \u003csugoi@google.com\u003e\nReviewed-by: Nicolas Capens \u003cnicolascapens@google.com\u003e\n",
