Termination Analysis

Add support to verify the category Termination-MainControlFlow on SV-COMP that contains programs for which termination should be decided.

I suggest you check out the follows paper:

• T2: Temporal Property Verification
• Termination-Checking for LLVM Peephole Optimizations
• Termination Analysis of C Programs Using Compiler Intermediate Languages
