For -O0 there might be unreachable BBs, which breaks the assumption that all the BBs have an auxiliary data structure. In this patch, we add another interface called findBBInfo() so that a nullptr can be returned for the unreachable BBs (and the callers can ignore those BBs). This fixes the bug reported https://llvm.org/bugs/show_bug.cgi?id=31209 Differential Revision: https://reviews.llvm.org/D27280 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@288528 91177308-0d34-0410-b5e6-96231b3b80d8
