[PATCH] D107102: [WebAssembly] Add new pass to lower int/ptr conversions of reftypes

[Thomas Lively via Phabricator via llvm-commits]

Oh right, that makes sense. I wonder if a custom DAG combine would be too late, too. At any rate, if you use the @llvm.debugtrap intrinsic in the IR replacement pass, it will lower to `unreachable` without needing to split any basic blocks.
