[wasm] Custom compression pass for wasm #49222

Open CoffeeFlux opened 3 years ago

CoffeeFlux commented 3 years ago

This will require first rewriting the ModuleSaw decoder in JS or C. By current estimates this gets us about 40k on dotnet.wasm with the interpreter-only config and even more with AOT. Writeup: https://github.com/WebAssembly/design/issues/1180

Interpreter:

  783,558 PM6.wasm.br
  742,510 PM6.msaw.br

AOT example:

10,142,245 calculator.wasm.br
 9,649,060 calculator.msaw.br
