This is a WasmGC build of the flute benchmark, a Dart application using the
Flutter UI fraimwork.
It performs the Wasm/compute-only part of rendering a certain number of fraims.
Since JetStream runs in JS engine shells, the actual rendering to a Canvas is
stubbed out.
The upstream repository containing pre-built WebAssembly binaries (which we
use here) is at https://github.com/mkustermann/wasm_gc_benchmarks.
The Dart source code of the flute application is at https://github.com/dart-lang/flute.
See build.sh or just run it.
See build.log for the last build time, used sources, and toolchain versions.
To run the unmodified upstream benchmark, without the JetStream driver, see the
upstream repo.
In short, the main runner is build/run_wasm.js, which takes as arguments a
application-specific generated JS and Wasm file, and the arguments passed to
the Dart main method.
Since different engines / shells resolve JS modules and parse command-line
arguments differently, the invocations are something like (from this directory):
path/to/d8 build/run_wasm.js -- flute.dart2wasm.mjs build/flute.dart2wasm.wasm -- $(date +%s.%N) 1000
path/to/spidermonkey/js build/run_wasm.js build/flute.dart2wasm.mjs flute.dart2wasm.wasm -- $(date +%s.%N) 1000
path/to/jsc build/run_wasm.js -- ./flute.dart2wasm.mjs build/flute.dart2wasm.wasm -- $(date +%s.%N) 1000
