How to add conditional branch code in tree node of a function?


Hi, guys,

How can I insert the conditional branch code in the function? I want to add
some dummy code before the end of the function, such as epilog, in the
level of tree node. I guess it is in c-del.c and insert some new declarations in the
function tree node list. Is it right? How can I do it? Any of comments and advices
will be highly appriciated!


Thanks!
