[PATCH] D23723: [SLP] Avoid signed integer overflow

[Michael Kuperstein via llvm-commits]

mkuper added a comment.

Using SaturatingAdd here seems right, but:

a) I'd prefer it if the test did check something beyond "don't crash".
b) It would be better it if one of the language lawyers looked at the SaturatingAdd implementation. In particular, I'm not sure casting an out-of-range unsigned to signed is well-defined.
