The following revision refers to this bug: https://chromium.googlesource.com/v8/v8.git/+/7c64d8837443afd182f9a3d26761091d81ac04fd commit 7c64d8837443afd182f9a3d26761091d81ac04fd Author: Deepti Gandluri <gdeepti@chromium.org> Date: Tue Jan 22 20:11:03 2019 [wasm] Use DefaultLowering for I64Atomic narrow operations Clusterfuzz generated test cases for narrow Load, CmpExchg nodes in which the index is a word64 expression. This was not handled correctly leading to a malformed graph. Use default lowering for all atomic narrow operations, and add reduced test cases in wasm cctests with the same sequence as the ones generated by binaryen for other I64Atomic operations as well.
