| The compilation trace lists functions that will be compiled in the core |
| snapshot. It is derived by unioning the output of Dart_SaveCompilationTrace |
| after startup from a few apps. |
| |
| To update this trace. |
| - In //topaz/runtime/flutter_runner/engine.cc, change kCompilationTraceDelayInSeconds to a non-zero value. |

| - Run `fx syslog | dart topaz/runtime/flutter_runner/collect_traces.dart topaz/runtime/flutter_runner/compilation_trace.txt` |
| - Boot and run a few apps, making sure to exercise the interesting paths before the timer set above expires. |
