Eli Friedman 05a71b0a6d [ScalarEvolution] Fix overflow in computeBECount. ... The current implementation of computeBECount doesn't account for the possibility that adding "Stride - 1" to Delta might overflow. For almost all loops, it doesn't, but it's not actually proven anywhere. To deal with this, use a variety of tricks to try to prove that the addition doesn't overflow. If the proof is impossible, use an alternate sequence which never overflows. Differential Revision: https://reviews.llvm.org/D105216		2021-07-16 16:15:18 -07:00
