Re: Questions about JVM to Scala.js IR compiler (GSOC project)

Hi, in the last few days I played a little with Scala.js building it and 
understanding the IR format and compilation. I've some new questions:

1) Am I correct to assume that the .sjsir file is structured with an 
"header" (containing things like the Scala.js version ecc. ecc.) and the 
serialization of the IR AST ? This means the GSOC project should parse the 
JVM code and generate the IR AST: then it can use the printers and 
serializers already existing. Obviously the “generate” phase is not this 
straightforward because it seems to me that the IR is much more “high 
level” than the JVM bytecode.
2) I don't really understand why the JS backend needs the .class files. At 
this phase I thought we don't have any dependency to the compiled Scala 
code and, while exploring a .sjsir file with scalajsp, it seems to me that 
all the necessary informations are already present.
3) Any suggestions about anything that I should look at ?
