In other words you are saying that a simulating termination analyzer
that correctly determines that the above Infinite_Recursion cannot
possibly halt is WRONG BY DEFINITION?
*THESE PEOPLE WOULD DISAGREE*
To prove (non-)termination of a C program, AProVE uses the Clang
compiler [7] to translate it to the intermediate representation
of the LLVM framework [15]. Then AProVE
*symbolically executes the LLVM program* and uses abstraction
to obtain a finite symbolic execution graph (SEG) containing
all possible program runs.
