BUILT_IN usage in tree-nested.c

[Richard Kenner]

    Why would Java need trampolines, isn't that only needed if
    you have nested functions?

You'd think so.

But what about the rest I listed that are used in the middle-end and not
defined by the Java front end?

Isn't it redundant for each front end to have to refine all the builtins?

And isn't it tricky to figure out which of the ons used by the
middle-end are *really* going to be needed?
