The key is whether the tree_code is "MODIFY_EXPR", which is (copied from
tree.def):
/* Assignment expression. Operand 0 is the what to set; 1, the new value.
*/
DEFTREECODE (MODIFY_EXPR, "modify_expr", tcc_expression, 2)
So, I think you should do something like:
enum tree_code code = TREE_CODE (stmt);
switch (code)
{
case MODIFY_EXPR:
...
}
Good luck,
