See #150075 (comment) for the motivation.

@rustbot rustbot added A-LLVM Area: Code generation parts specific to LLVM. Both correctness bugs and optimization-related issues. S-waiting-on-review Status: Awaiting review from the assignee but also interested parties. T-compiler Relevant to the compiler team, which will review and decide on the PR/issue. labels Jul 1, 2026

@bors r-

We shouldn't use the intrinsic on wasm if it's broken, LLVM has had some problems bringing those up. Please don't disable it unconditionally since it's otherwise working and getting tested.

Ah, ok. I'll close this since it isn't the right approach.
