Interface for manipulating the abstract syntax tree

["Ferad Zyulkyarov" <feradz at gmail dot com>]

Hi,

I try to change the front-end tree structure of a c/c++ program as a
side effect of execution of a pragma. The operations that are involved
is to walk through in a tree (i.e "C" block), insertion of a tree
(i.e. statement, block, declaration) in the abstract syntax tree and
deletion of a tree (i.e. statement, block, declaration).

I am quite new to the gcc code and I could only find that the function
add_stmt(tree) inserts a statement.

I suppose that a lot of gcc developers here doing this routinely. I
would appreciate your help and advices a lot.

Thanks in advance,
