I found main function which locate js/src/shell/js.cpp:5103.
It call Shell(JSContext *cx, OptionParser *op, char **envp).
I understand function flow.

Last call function execute js-operation such as add or sub.
I found js::ion::CanEnter in js::RunScript.
I can't understand how call foldsTo function in js/src/ion/MIR.cpp.
I'd like to know how call foldsTo function from js::ion::CanEnter to fix this
