Hi Ian
I have spend these 3 days to read lots of documents about Go and
gccgo. And scan many papers about escape analysis.
I plan to use about next 2 days to read more source code of gccgo.
In order to dig more and come to a more detailed and efficient
proposal. I need your suggestion:
-Which codes must I read firstly, and which are the most
important to read very carefully?
-Do you have suggestions on where should I start? What small
implementations can I firstly accomplish?
-What would be the background knowledge needed? As there would
be more requirements regarding this specific idea not now obvious.
-Are there some documentations or papers should I read now?
I really appreciate your help =D
