The fix is setting\n`device_supported: false` for libart(d)-simulator module in the .bp\nfile (`m checkbuild` attempted to build it for arm32 and failed).\nOriginal commit message:\n\nVIXL simulator for ART (Stage1)\n\nQuick User Guide: test/README.simulator.md\n\nThis CL enables running ART run-tests in a simulator on host machine.\nSome benefits of using this simulator approach:\n- No need to use a target device at all.\n  Save developers from solving the device troubles: build, flash, usb,\n  adb, etc.\n- Speed up development/debug/test cycle.\n- Allows easy debugging/testing new instruction features without real\n  hardware.\n- Allows using a smaller AOSP Android manifest master-art.\n\nThe Stage1 CL provides support for running 30% of current run-tests.\nThe rest unsupported test cases are kept in knownfailures.json.\n\nFuture work will be supporting proper stack frame layout between\nsimulator and quick entrypoints, so that stack walk,\nQuickArgumentVisitor, deoptimization, etc can be supported.\n\nThis CL adds libart(d)-simulator-container library to the ART APEX. It\nhas caused the following increase of the APEX size (small, about 0.13%\nfor release APEX, measured for target aosp_arm64-userdebug):\n Before:\n   88992 com.android.art.debug.apex\n   51612 com.android.art.release.apex\n  112352 com.android.art.testing.apex\n After:\n   89124 com.android.art.debug.apex\n   51680 com.android.art.release.apex\n  112468 com.android.art.testing.apex\n\nChange-Id: I461c80aa9c4ce0673eef1c0254d2c539f2b6a8d5\nTest: art/test.py --run-test --optimizing --simulate-arm64\nTest: art/test.py --run-test --optimizing --host\nTest: m test-art-host-gtest\n"

For\nblocks that we can and want to schedule:\n1) Build a dependency graph for instructions. It includes data\n   dependencies (inputs/uses), but also environment dependencies and\n   side-effect dependencies.\n2) Schedule the dependency graph. This is a topological sort of the\n   dependency graph, using heuristics to decide what node to schedule\n   first when there are multiple candidates. Currently the heuristics\n   only consider instruction latencies and schedule first the\n   instructions that are on the critical path.\n\nTest: m test-art-host\nTest: m test-art-target\n\nChange-Id: Iec103177d4f059666d7c9626e5770531fbc5ccdc\n"
