asmjs2wasm

This repository contains the source for asmjs2wasm, a command-line tool that converts asm.js to the WebAssembly text format.

This tool is currently in development and incomplete

Current limitations of the tool:

• The tool only accepts files containing a single top-level asm.js module function definition. To apply this tool to an arbitrary JS file containing an asm.js module, all the surrounding asm.js must be stripped out.
• The tool assumes that the incoming asm.js has already been validated and may crash or generate wrong code otherwise.
• Until the WebAssembly text format is finalized, the tool emits the temporary S-Expression-based text format defined by WebAssembly/spec.
