  "message": "Std:unordered_map removed from Optimizer for improved performance\n\nThe use of std::unordered_map was the main source of slowdowns in\nthe optimizer code, so it was re-written without any maps. In order\nto do so, the information originally carried by the maps was moved\nto user-defined information stored within Subzero classes. The\noptimizer now manages the memory used to store this information.\n\nBug swiftshader:69\nBug b/67872293\n\nChange-Id: I2757169f0d3d467766317af6e00e149b4317fb9c\nReviewed-on: https://swiftshader-review.googlesource.com/19508\nTested-by: Alexis Hétu \u003csugoi@google.com\u003e\nReviewed-by: Nicolas Capens \u003cnicolascapens@google.com\u003e\n",
