INFILE must be in human-readable LLVM disassembly form (i.e., as text,
|
|
not binary).
|
|
PATH-TO-JS-ENGINE should be a path to the JavaScript engine used to
|
|
run the compiler (which is in JavaScript itself). You can later use
|
|
the same engine to run the code, or another one, that is a separate
|
|
issue. If you do not provide this parameter, you should define
|
|
JS_ENGINE = ... in a file at ~/.emscripten.
|
|
SETTINGS is an optional set of compiler settings, overriding the defaults.
