A bunch of hackish fixups for testing of SpiderMonkey support. We should
get rid of these ASAP.
This is meant to be run using BINARYEN_SCRIPTS in emcc, and not standalone.

import emscripten
binaryen_root = os.path.abspath(os.path.dirname(os.path.dirname(__file__)))
js_target = sys.argv[1]
wast_target = sys.argv[2]
wasm_target = wast_target[:-5] + '.wasm'
# convert to binary using spidermonkey
'''
using something like
mozjs -e 'os.file.writeTypedArrayToFile("moz.wasm",
new Uint8Array(wasmTextToBinary(os.file.readFile("a.out.wast"))))'
investigate with
>>> map(chr, map(ord, open('moz.wasm').read()))
or
python -c "print str(map(chr,map(ord,
open('a.out.wasm').read()))).replace(',', '\n')"
