<p class="MsoNormal">See <a href="https://reviews.llvm.org/D63036">https://reviews.llvm.org/D63036</a> for the full patch and description. Essentially, the Constant::canTrap API is going away. To make this work, the semantics of division and remainder constant
expressions are changing slightly, so division by zero produces poison, not undefined behavior. (The corresponding instructions still have undefined behavior.) This change should make writing and understanding IR optimizations easier.<o:p></o:p></p>
