I start to learn graal recently, as I found few documents publicly
available, I send my questions here.
As for the CFG attached, i am curious about the following questions.
1) why the node "If" is often after a node "%", what functionality does
the node "%" achieve?
2) what is the node "unsafeload"used for, why is it always immediately
after the startnode?
3) How is the framestate used? I see the nodes "begin" and "endnode" in
the CFG, does each pair delimit one framestate?
Thanks a lot for your help.
