[Question][Hw5] About node

[nubi12336]

I thought when we run the code, we have to use semantics.transfer_node
for each node in given table (All labels have bottom memories) to get a new table.
Thus, I tried to do above thing but I failed.

In example1.c, there is int x = source(). In my thought, this line is a node, so it is in a given table. Let this node is c.
Then, in transfer_node llctx c memory, match node with Atomic instr and instr is int x = source().
In this instr, there is a first operand x and second operand source(). Therefore, I used utils.is_source instr and I added this new x -> T to memory(It was bottom memory).

Are there something wrong with above statements..?
When I tried to print out new memory, it occurs error Cannot find lhs of declare dso_local i32 @source(...) #2 Fatal error: exception Not_found.
Did I misunderstand about Node or Table?

I think just assignment is not working. int x = 0 also occurs error.

x is not a first operand.

Please see this document. (https://github.com/prosyslab-classroom/llvm-primer/blob/master/data-structure.md)

I see. x is also just instr. Right?

Yes.
