Q: Is there a way to get a string representation of a tree, particularly a tree that represents a single variable? get_name() does not work for variables like D.####


 Q: Are there functions to change operands of a tree or do we have to build EXPR trees ourselves with some other function?

A: There are some macroes named "build0", "build1", .... in tree.h which can be used to build gimple trees. For changing operands, there are 3 steps: build new operands, remove old operands and place new operands.
