Hi all, I have yet another question that has arisen as i have started testing my code. Basically I am trying to get the type that is being used in throwing an exception.
Is there a simple macro i can use to get the type of an exception from a THROW_EXPR? I think this is a matter of getting the TREE_TYPE for the value passed into the function: except.c: build_throw(tree exp) I have been printing out the TREE_CODE of the node that comes from calling TREE_TYPE(exp) inside that function, and i think from what i can tell this gives the correct value for the type of the exception being thrown (maybe i should also pass it through the prepare_eh_type() function too). The problem is: How do i get a reference to the expression tree passed into the build_throw() method from a THROW_EXPR node or at least its type? OR How do i get a reference to the node with the type of the exception for a THROW_EXPR? Note: I also tried to change the THROW_EXPR node to have 2 operands instead of 1 in (cp-tree.def) and then use build2() with the original exp node instead of the existing build1() and attached the original exp node to it. This had other disastrous consequences which i kind of expected. I was not sure if I could just add an additional operand to the THROW_EXPR node. I figured that all other commands would just use operand 0 and ignore the new operand but it seems to fail with an ICE, so i gave up that line of thinking... Thanks for any help/info on this.
