Bug ID: 25838
Summary: AOSP build fails due to assertion failure at
llvm/include/llvm/Support/BranchProbability.h:183
Product: new-bugs
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org

Failed when building AOSP for shamu with LLVM tip. This only fails with LLVM
tip, not with the prebuilts/clang in AOSP.
