[PATCH] D87149: [InstCombine] erase instructions leading up to unreachable

[stephan.yichao.zhao via Phabricator via llvm-commits]

stephan.yichao.zhao added a comment.

Checked llvm::isGuaranteedToTransferExecutionToSuccessor from https://llvm.org/doxygen/ValueTracking_8cpp_source.html. 
Yes, non-throw and return calls are considered a through instruction. But it does not check volatile specially about whether such an access can abort a program.
