[cfe-dev] Clang Control Flow Graph?

[Jordan Rose]

Hi, Masoug. No, I don't think it's safe to make that assumption, even if it's true today. You'll have to use a visited set; llvm::SmallPtrSet should be able to handle it quite well.

Best,
Jordan

I was trying to traverse the CFG but terminators like for loops "trap" me into an infinite loop; the successors have a path back to the predecessor of some blocks. My thinking was that if the block ids were assigned in a specific order, I may be able to use them as a way to avoid running into infinite loops (and stack overflows).
