By the way, I'm not sure whether this bug happens on other architectures with xray support. The most straightforward reference I found to emitting conditional tail calls was https://github.com/llvm/llvm-project/blob/c60aa430dc4085d276a630699323068bf36bd9d8/llvm/lib/CodeGen/BranchFolding.cpp#L1536, and `canMakeTailCallConditional()` is only true on x86. I'm not sure if I am missing other places that might generate these though.
